RT 3000 Toughened Cyanoacrylate with Extended Heat Resistance

 

RT 3000 is a toughened cyanoacrylate with improved impact and peel strength for maximum flexibility.

Its increased temperature resistance make RT 3000 suitable for a wide range of applications.

It bonds to a variety of surfaces including aluminium, steel (including zinc plated )

RT 3000 is excellent for bonding metal to rubber in all combinations.
