Hydropel® H034-A is a thixotropic, prepromoted, modified vinyl ester resin. Maximum resistance to osmotic blistering when used for the skin coat or the complete composite. Excellent strength and toughness of the finished composite part. Provides improved resistance to cracking caused by the flexural failure of the laminate even when used only for the skin coat. Good surface profile, with reduced post cure on finished parts. Provides the toughness and resistance to heat needed to make durable tooling that will require minimal maintenance. Meets MACT requirements for low hap resins in the marine industry.
