This is a flexible structural adhesive with especially good adhesion to a wide range of industrial materials including metals and reinforced plastics.
The performance characteristics of this product are similar to the slower curing 3M Scotch-Weld DP190 which has found widespread acceptance in industrial bonding applications. After application from the cartridge, the product has a useful work life before contact with the second surface of approximately 25 minutes which makes it suitable for medium to large constructions; while still giving the benefit of rapid handling strength (approximately 2.5 hours). Performance is characterised by a combination of high Peel and Shear strength.
