EPON 815C
Low Viscosity Liquid Bisphenol A Based Epoxy Resin Containing A Commercial Grade of n-butyl glycidyl Ether, Allows For Easy Pumping And Wetting of Pigments And Fillers
EPON 815C is a low viscosity liquid bisphenol A based epoxy resin containing a commercial grade of n-butyl glycidyl ether. EPON Resin 815C is functionally equivalent to EPON Resin 815, and is suitable as a replacement for EPON Resin 815 in most applications.
EPON 815C Application Areas/Suggested Uses
- Adhesives
- Electrical casting and encapsulation
- Contact and vacuum bag laminating
- Solventless coatings
- Floor topping and grouting compositions
- Tooling
EPON liquid epoxy resins when properly formulated and cured provide an inert end-product with a unique combination of properties. They are suitable for use in high performance applications such as coatings, adhesives, civil engineering, electronic and electrical insulation, composites and fiber sizing. Cured EPON resins are generally regarded as being high strength materials, since many commonly used systems provide tensile strengths greater than 10,000 psi and modulus values greater than 400,000 psi. One of the most widely recognized applications of cured EPON Resin 815C is strong adhesion to a broad range of substrates. Such systems exhibit shear strength of up to 6,000 psi (41 Mpa). One factor which contributes to this property is the low shrinkage shown by these systems during cure. Compared to other polymers, epoxy resins have low internal stresses resulting in strong and durable finished products.
Benefits
- Low viscosity, allows for easy pumping and wetting of pigments and fillers
- 100% reactive. Reacts with a full range of curing agents
- Provides minimal reduction of performance properties
