Tužidlo H 512

Hardener H 512 is a liquid low-viscosity hardener for epoxy resins. The hardener is based on cyclic diamine. It is suitable for all types of laminations at temperatures above 15°C and where high thermal resistance is required. For proper curing, post-curing at a minimum of 50°C for at least 3 hours is necessary after solidification. Higher thermal resistance of the cured resin can be achieved by post-curing the system at elevated temperatures of 90-100°C. The working time is 150 to 180 minutes. Ratio to resin LH 160 : H 512 = 100 : 23(g) Ratio to resin LH 260 : H 512 = 100 : 23(g)
