Technical datasheet 01/01/2007 RESOLTECH 3050C Hardener 3054C Structural Epoxy Adhesive Structural epoxy adhesive for demanding applications requiring rigid adhesion films. Long pot life for large surface applications. Ambient temperature curing. 1/1 mixing ration in volume. The Resoltech 3050C epoxy adhesive is a rubber toughened, high performance adhesive that will enable bondings with very high mechanical resistance (310 kg/cm2). It’s curing at ambient temperature and 1/1 mixing ratio in volume makes of the 3050C an easy product to work with. It will enables the bonding of materials of different dilatations coefficient and will resist in a large range of operating temperatures from -50°C to +80°C, with a maximum service temperature of 140°C. It is a solvent less adhesive with no contraction upon curing.
