Penloc 1:1 is the original ‘pink & green’ ultimate fast curing (5 mins) 2-part toughened acrylic structural adhesive. Many have tried to copy this adhesive and all have failed to match its unrivalled high performance and amazing quality. Penloc 1:1 structural adhesive will bond almost any material combination giving an extremely high strength join. It will tolerate -55°C to +125°C. Penloc 1:1 can be applied without the use of a mixer nozzle. The adhesive components should be pressed out one on top of the other (Bead on Bead). When the two substrates are clamped together this further mixes the adhesive. This is fine for non critical bonding applications. However for best performance and adhesive integrity we recommend using a mixer nozzle to ensure the adhesive has mixed in a 1:1 ratio.
