Product Overview

BRT Optically Brightened Laminating Epoxy is a Super Sap® formulation. This optically brightened, clear laminating system is designed specifically for ultra-white cosmetic applications, such as surfboard laminations over EPS (expanded polystyrene) or PU (polyurethane) foam. Based on Entropy Resins® classic CLR – CLEAR Epoxy Resin, BRT Optically Brightened Laminating Epoxy Resin can be paired with all CLR Clear hardeners.

Available in CLX (Extra Fast), CLF (Fast), and CLS (Slow) cure speeds. Hardener speeds can be combined to customise working times.

CLX Extra-Fast Cure: 18 min pot life, 2 hr tack-free time, recommended Full Cure 7 days @ 25°C.

CLF Fast Cure: 21 min pot life, 4 hr tack-free time, recommended Full Cure 7 days @ 25°C.

CLS Slow Cure: 43 min pot life, 8 hr tack-free time, recommended Full Cure 7 days @ 25°C. Post cure recommended.

Two-part epoxy resin kits are comprised of BRT Epoxy Resin and CLX (EXTRA FAST), CLF (FAST), or CLS (SLOW) Hardener.

For dark colour substrate applications, we recommend our CLR formula.

Best Uses

  • White Surfboards
  • Stand Up Paddle Boards


Application Tips:

    • For best results, measure the two components by weight at the correct mix ratio.
    • Always mix product for at least two minutes, scraping the container to ensure complete mixing.
    • Try to use the product in a controlled temperature environment within the optimal specifications of the product. Avoid high humidity or cold ambient temperatures.
    • For optimal bonding performance, be sure the surface is dry and free of dirt, debris, and oils. Mechanical preparation of the surface from sanding is highly recommended.
    • Build sample coupons using proposed materials and processes to fully understand the curing characteristics of the epoxy in your working environment and compatibility of the epoxy with other materials.
    • Avoid using BRT over dark coloured surfaces as optical brightener could affect appearance.
