Can I use Penloc® to bond any substrate?
Penloc® will bond just about any material combination with the exception of low surface energy materials such as polypropylene and polyethylene. It is suitable for bonding most metals, plastics, Acrylic, carbon fibre, modern composites, GRP, wood, glass, stone, marble, Corian® and so much more. Bond strength testing achieve 276kg/cm² on steel to steel substrates.
Can I use Penloc® for indoor as well as outdoor applications?
Yes, Penloc will tolerate usual weathering and temperatures from -55°C to +200° depending on the grade used. For more specific information please refer to individual product technical datasheets.
Does the adhesive smell?
Standard Penloc 1:1 does have an odour. However, Penloc 1:1R is non odour and is ideal for working in areas with limited ventilation or on-site work where an odour is not desirable.
Can I use it to bond metals that require powder coating afterwards?
Penloc® HP is designed specifically for bonding metals that require powder coating afterwards. It will tolerate 180°C and increases in strength at this temperature. Penloc® VT Plus is a thicker, longer curing adhesive that offers good gap fill properties and can also be used to bond metals that require powder coating after bonding.
How do I prepare the surfaces that I want to bond together?
All surfaces that require bonding should first be cleaned using Eurobond Surface Cleaning Wipes (isopropyl impregnated) to remove any oil, grease or dirt, then lightly abraded and then cleaned again to remove any dust or debris. Do not use meths, white spirits or aromatic cleaners as these will leave a microscopic film on the substrate which will contaminate the bond line and act as a barrier preventing the adhesive from adhering properly to the surface. We also recommend using Protective Nitrile Gloves when handing adhesives.
Do I need to use a mixer nozzle with the adhesive?
For critical bonding we would recommend using a Minimixer nozzle fitted to the 12ml & 50ml cartridges. This mixes the adhesive to its optimum 1:1 ratio and will give the best adhesive performance. However for non-critical bonding you can apply the adhesive direct from the cartridge bead on bead. This is where one component flows on top of the other and starts to flow/merge into each other. When you clamp the bonded parts together this further mixes the adhesive and it will cure. However, some of its performance will be reduced.
Please note; 50ml Penloc VT Plus cartridges and 400ml cartridges take different mixer nozzles. Always check the individual product to confirm correct nozzle required.
How many mixer nozzles will I need?
This depends on each application. It is best to prepare all the surfaces first. This way you will minimise stop start production which is where you will find you use more nozzles. Depending on the grade you use, it takes about 1-2 minutes for the mixed adhesive to thicken in the nozzle and it will have to be replaced with a new one. Penloc® VT Plus will take about 10 minutes to thicken in the mixer nozzle before it has to be replaced.
How do I prepare the surfaces that I want to bond together?
All surfaces that require bonding should first be cleaned using Eurobond Surface Cleaning Wipes to remove any oil, grease or dirt, then lightly abraded and then cleaned again to remove any dust or debris. Do not use meths, white spirits or aromatic cleaners as these will leave a microscopic film on the substrate which will contaminate the bond line and act as a barrier preventing the adhesive tape from bonding properly to the surface.
How much pressure should be applied when applying acrylic foam tape?
The aim of applying pressure is to achieve 100% wet-out of the adhesive. To achieve good wet out and ultimately a good bond, it is essential to ensure that the pressure is firm and even. As a rule a minimum of 15psi or 100kpa should be used for rigid materials. More flexible substrates may need less pressure. The size, shape of components being bonded and tape placement will also need to be considered in determining how much pressure should be applied.
Why does acrylic foam tape not feel very sticky to the touch?
Whilst acrylic adhesives tend to be firm and dry to the touch, this is not an indication of their final bonding properties. An acrylic foam tapes adhesion builds over a 72hour period to form an unsurpassable bond. Adhesives such as rubbers and hot melts, whilst feeling very tacky, do not have the same physical properties from a temperature, plasticiser or solvent resistance point of view. Certain acrylic adhesives are modified by adding tackifiers to increase initial adhesion, but this is generally at the expense of a lessening of performance.
How much tape to I need to support a given weight?
Typically when using our 3 series, 4 series and 6 series range of tapes for non-critical indoor applications allow for 25cm² per kg of weight.
For critical indoor or outdoor applications using our 3 series, 4 series and 6 series range of tapes allow for 60cm² per kg or weight.
When using double coated foam tape (EB808F, EB810P, EB815P) for indoor applications, allow for 100cm² to support 1kg of weight.
These figures represent the maximum levels which include a high safety margin. They can potentially be reduced where less surface area is available. This has to be determined by the customer through suitable testing.
What is the purpose of having varying thicknesses of tape?
The thickness of an acrylic foam tape allows it to compensate for mismatch between two surfaces. By choosing a tape that accommodates mismatch, the tape is allowed to achieve optimum coverage of the surfaces that is bonding. The greater the surface coverage achieved, the more effective the bond will be. For rigid materials the general rule of thumb is the tape should be twice the thickness of the material mismatch. Acrylic foam tapes are designed to provide stress relaxation properties. Its acrylic foam core allows the tape to elongate and relax when stressed. This means the stress is distributed through the foam core and not concentrated in the adhesive bond line, which is often the case of adhesive failure. Acrylic foam tape can stretch up to three times its thickness to accommodate thermal expansion between different materials.

Vitralit® UV Curing Adhesives
How do UV adhesives work?
UV Adhesives are transparent adhesives that will bond plastics, glass and some metals. They remain in a liquid state until they are exposed to high intensity UV light.
What type of UV Light do I need?
Depending on the particular product you will need a UV light system that emits high intensity (minimum 40mW/cm²) UV(A) at either 365nm or 405nm. Please refer the product technical datasheet.
What type of UV Light System do I need?
This really depends on your application. If you have a high speed production process then you could integrate a PLC controlled UV light system such as the Honle or for large surface area bonding you may want to use the Honle.
If you are an artisan craftsman working on small handmade pieces then consider a high power LED Torch, LED Laser Pen or an LED hand/flood lamp. For laboratory work or bonding multiple parts you may want to consider a UV Curing Chamber.
Is using UV Adhesives and UV light sources harmful?
We always recommend wearing protective gloves when using adhesives and of course wear UV resistant protective glasses when using a UV lamp. Never look directly at the UV light source and always use the UV light in a protected area. For example in a workshop use black partitions or screens to screen off the UV bonding area. On a high speed production line consider using polycarbonate UV resistant UV light guards in front of the light source. Ensure you read the adhesive safety datasheet before using the glue. Always read the operator safety instructions when using high intensity UV light
Can UV adhesives be used as a coating?
Yes, we can supply dome coating adhesives and conformal coating adhesives.
Are UV adhesives suitable for medical applications?
We supply a large range of USP Class VI and ISO 10993 medical grade UV adhesives used to bond many different applications including, plastic tube/bag combinations, tube/cannula sets, syringe needle bonding, blood filters and much more.
Do I need to treat the materials I want to bond before using the adhesive?
All substrates need to be clean and free of grease, dirt or moisture. Surfaces can be cleaned with Eurobond Adhesives Surface Cleaning Wipes or liquid Isopropyl alcohol. Some plastic such as PP, PE or SAN may need pre-treatment using plasma or corona discharge. Refer the the adhesive technical datasheet for its suitability to certain substrates. Or call our technical team to discuss your specific application.
Elecolit® Conductive Adhesives
How do I prepare the surfaces that I want to bond together?
All surfaces that require bonding should first be cleaned using Eurobond (isopropyl impregnated) Surface Cleaning Wipes to remove any oil, grease or dirt, then lightly abraded and then cleaned again to remove any dust or debris. Do not use meths, white spirits or aromatic cleaners as these will leave a microscopic film on the substrate which will contaminate the bond line and act as a barrier preventing the adhesive from adhering properly to the surface.
Can I use conductive adhesives to replacer solder?
Electrically conductive adhesives are often used as a more effective alternative to conventional soldering. They are particularly suitable for making electrical contacts on temperature-sensitive substrates, as their curing temperature lies clearly below soldering temperature. In addition the adhesives are much more flexible than solder and are therefore better able to withstand vibrations. A further advantage over soldering is that conductive adhesives are lead- and solvent-free.
What conductive medium is used in Elecolit® conductive adhesives?
All Elecolit® conductive adhesives use silver flakes as the conductive medium.
What are the main differences between a one or two component conductive adhesive?
Typically one component electrically conductive adhesives require heat to accelerate their curing profile and are solvent based and effectively air dry when the adhesive is applied as a coating and exposed to the atmosphere. Two component conductive adhesives will only start to cure when part A is mixed with part B. This means they are less wasteful as you will only mix and use the quantity required.
I need conductivity in one direction.
Anisotropic conductive adhesives (ACA) contain special conductive particles in the µm range, which conduct electricity only in one direction. These adhesives are used, for example, in many sensitive structures on circuit boards, such as LCD connections or contacting flexible PCBs, or for bonding antenna structures on RFIDs.
I need conductivity in all direction.
Isotropic conductive adhesives (ICA) are electrically conductive in all directions. They are used in applications such as chip contacting and bonding electrically conductive SMDs.
How do I apply the adhesive?
Single-component adhesives can be applied with dispensers, or jet- or screen-printed. Two component adhesives can be applied by hand or screen printed.
Eurobond Flexible MS Polymer Adhesives
Do I need to prepare the surfaces prior to bonding?
We would always recommend that you lightly abrade and clean all surfaces that require bonding. Eurobond Surface Cleaning Wipes are best suited for this. Do not use Meths, White Spirits or aromatic cleaners as they will leave a microscopic film on the surface which acts as a barrier and contaminant which will prevent the adhesive from bonding properly to the substrate. Bricks, timber and plasterboard need to be clean and free from any dust or dirt.
Do I need to prime the surfaces prior to bonding?
MS Polymers are designed for primerless adhesion to most surfaces.
How long will the adhesive take to cure?
MS Polymers cure by the absorption and reaction with surface and atmospheric moisture. Typically at room temperature and 50%RH an MS Polymer will cure up to 3mm thickness in 24hrs. Eurobond Solo, has a very fast and strong initial grab meaning your parts will self-support after just 10 minutes and will continue to cure over 24hours. Eurobond QuickFix is a unique 2-part flexible MS Polymer which will fully cure in just 4 hours.
Can I apply an MS Polymer adhesive in any temperature?
We recommend applying this adhesive in temperatures between 5°C and 35°C. The adhesive will not cure when it’s applied in temperatures below 5°C.
Can I apply the adhesive in the wet?
Yes, MS Polymers can be applied directly to damp surfaces.
Can I use an MS Polymer for sealing or bonding against fire?
Eurobond SAFE FIX®FR300 is a fire resistant MS Polymer adhesive and is designed to bond and seal construction and many other joints against fire.
Can I use an MS Polymer adhesive in a food contact area?
Eurobond ClearFix is a Food Safe adhesive and can be used to bond materials together that may be in direct contact with food.
