Product Description

SUPER SAP® CLR Clear Laminating Epoxy 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 colour, low yellowing epoxy resin such as high colour 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 EXTRA FAST (CLX Extra Fast Hardener), FAST (CLF Clear Fast Hardener), and SLOW (CLS Clear Slow Hardener) cure speeds. Hardener speeds can be combined to custom working times.

Extra Fast Cure: 18 min pot life, 2 HR tack-free time.

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

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

2 Part Epoxy Kits are comprised of:
Super Sap CLR Epoxy and

For white substrate applications, we recommend our BRT formula.


Best Uses

Entropy Resins’ coating and laminating epoxies are SUPER SAP® Formulations. Designed for versatility, they can be used in a wide range of applications from laminating fiber-reinforced composites to thin film coatings. Featuring simple 2:1 mix ratios and a variety of cure speeds, they are engineered for ease of use. Superior strength, excellent adhesion to many surfaces, industry-leading clarity, and UV epoxy stability make these epoxies the right choice for coating and laminating projects.

    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 small test samples before starting a larger scale project.
    • Read our Entropy Resins Care and Handling instructions for the best tips on storage.

    Heat is your friend, that is the mantra for using resin. Read more about how to save crystallized resin here.

    Although our room temp cure systems are designed not to need a post-cure, all epoxies will benefit from the addition of heat as a post-cure. Read more about why post-curing is important.

    CCR resin states it’s Water clear. Water clear is a reference to opacity, not "colour". Meaning our resin is as transparent as water, however, it might have a slight red hue to it.

    Colour has to deal with the resin imparting a colour over the substrate. In the case of white surfboards, you don't want any colour. In the case of woods, sometimes a bit of colour helps. An example is ONE over wood where a lot of users think the wood looks richer with the colour of ONE.

    There is no such thing as NO VOCs! All epoxies, resins and polyesters emit VOCs. Read more about VOCs here.
