Epoxy Polyacrylates for Low Temperature Cure

EPON™ epoxy polyacrylate resins provide both epoxy and polyacrylate reactive groups. As a result, these resins are robust and react readily at low temperatures (below 50°F) and very rapidly at ambient temperatures, as compared to standard epoxy resins. Key features of Westlake Epoxy's epoxy polyacrylate resins include:

Low to moderate viscosities
High reactivity at ambient and low temperatures
Reactivity relatively independent of mass
Superior wetting characteristics leading to improved adhesive properties as compared to standard epoxy resins
Good physical strength and toughness
Enhanced resistance to amine blush

Typically combined with EPIKURE™ aliphatic and cycloaliphatic amine curing agents, epoxy polyacrylate resins are tough and easy to work with and may be used for applications such as:

Product	Resin Type	Viscocity at 25^oC, cP	Eq. Weight⁽²⁾ g./eq.	Description	Coatings	Construction	Composites	All Others⁽¹⁾
EPON Resin 8021	Epoxy Polyacrylate	85 – 115	150	Very low viscosity epoxy diacrylate resin that imparts high reactivity and superior wetting. 13 minute gel time with TETA.
EPON Resin 8111	Epoxy Polyacrylate	800 – 1100	140	Low viscosity epoxy triacrylate resin that gives rapid reaction and low temperature cure. 2.5 minute gel time with TETA.
EPON Resin 8161	Epoxy Polyacrylate	1800 – 2400	177	Moderate viscosity epoxy diacrylate resin with performance similar to EPON Resin 828. 27 minute gel time with TETA.

HIGHLY RECOMMENDED:

¹ Other applications include adhesives, electrical castings, electrical laminates and fibers

² Based on reaction with active amine hydrogen. The reaction occurs with epoxy- and acrylate-groups.
