Epoxypro EPR-800 Ultra-Clear Low Viscosity Epoxy Resin
EpoxyPro EPR-800 Epoxy Resin
Low-Viscosity Blend of Bis-A / Bis-F Epoxy Resin — High-Performance Universal Part A
EpoxyPro EPR-800 is a low-viscosity blended Bisphenol-A / Bisphenol-F epoxy resin engineered as a universal, high-performance Part A suitable for virtually all epoxy applications.
With a controlled viscosity of 800–1100 mPa @ 25°C, EPR-800 offers excellent flow, deep penetration, strong wetting of timber and fibreglass, and highly reliable mechanical bonding across a wide variety of substrates.
As the primary backbone resin in the EpoxyPro UNI-SYSTEM™, EPR-800 represents over 90% of all Part A usage due to its consistent handling, broad application range and compatibility with all EpoxyPro hardener options.
