Product Overview

CLR Clear Laminating Epoxy is our flagship, high-performance, clear-coating epoxy system. A Super Sap® Formulation, the CLR system is a water-clear, UV-stabilized epoxy system for applications that require a low-color, low-yellowing epoxy such as high-color applications. This system features a quick air-release and world-class UV resistance package. 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.

Two-part epoxy resin kits are comprised of CLR Clear Laminating Epoxy Resin and CLF (FAST) or CLS (SLOW) Hardener.

For white substrate applications, we recommend our BRT Optically Brightened Laminating Epoxy Resin formula.

Instructions

Application Tips:

  • For best results, measure the two components by weight within 5% of the recommended mix ratio.
  • Always mix product for at least two minutes, scraping the container to ensure complete mixing.
  • Use products in a controlled environment. Avoid high humidity and cold temperatures.
  • Amine blush, a by-product of the curing process, appears as a wax-like film cured epoxy and is more noticeable in cool, moist conditions. It can clog sandpaper and inhibit subsequent bonding. Blush is water-soluble and easily removed with clean water (not solvent) and an abrasive pad.
  • For good adhesion, epoxy bonding surfaces should be clean, dry, and sanded.
  • If unfamiliar with the product, create smaller test samples before starting a larger-scale project.
