Epoxypro EPR-900 Ultra-Clear High Viscosity Epoxy Resin
EpoxyPro ERP-900 Epoxy Resin
High-Viscosity Bis-A Epoxy Resin, Structural, Filling & Industrial Repair Grade
EpoxyPro ERP-900 is a high-viscosity Bisphenol-A epoxy resin (Part A) engineered for applications requiring increased body, reduced flow, and enhanced stability on vertical or uneven surfaces.
With a controlled viscosity of 11,000–15,000 mPa @ 25°C, ERP-900 offers excellent gap-filling performance, strong mechanical bonding and outstanding compatibility with fillers, aggregates and reinforcing materials.
As a high-bodied resin in the EpoxyPro UNI-SYSTEM™, ERP-900 is ideal for structural bonding, industrial repair, grouting, flooring patching and any application where controlled flow is required.
