4:1 High Hardness Epoxy Resin for Composite Material
Model: 6992AB Mixing Ratio: 4:1 by weight
6992AB is a 4:1 high hardness composite epoxy resin designed for fiberglass laminating, carbon fiber laminating, LED potting, mold filling and selected craft applications. The formula focuses on firm cured strength where reinforced structures or filled parts need higher hardness after curing. Its mixing ratio supports stable processing for composite layers and rigid encapsulation work. Good adhesion helps resin connect with fiber surfaces, mold cavities and coated parts. This product suits applications that require stronger cured structure, clean filling behavior and dependable hardness across composite and potting use.
