Product Overview

SUPER SAP® CLR Epoxy Resin is our flagship, high-performance clear coating epoxy resin system.  The CLR system is a water clear, UV stabilized epoxy system for applications that require a low color, low yellowing epoxy resin such as high color applications.  This system features a quick air-release and world-class UV resistance package. SUPER SAP® CLR works with multiple hardeners to match your working parameters.  It has an ideal viscosity for a wide range of applications that use hand layup techniques with fast room temperature cures.

Available in FAST and SLOW cure speed – Hardener speeds can be combined to customize working times.

Fast Cure: 21 min pot life, 4 HR tack free time

Slow Cure: 43 min pot life, 8 HR tack free time
