Product Details

Entropy Clear Laminating Epoxy Resin (CLR) is the base component of the Clear (CLR) low-viscosity, low-color, UV-stable system for composites, coatings & adhesive applications.

It's optimized for hand layup, room temperature processes, or infusion laminating of wood, fiberglass, carbon, or Kevlar. Its air release and UV protection create clearer cured laminates with excellent color stability.

CLR resin forms a hard plastic surface when cured with Entropy hardeners: CLS slow hardener offers long pot life, CLF fast hardener offers shorter pot life and faster curing, and CLX hardener has the fastest tack-free time. The CLR system has a bio-content greater than 30% & can be modified with epoxy-compatible colorants & fillers.

NOTE: For white cosmetic applications, use Entropy Optically Brightened Epoxy Resin (BRT) (uses the same hardeners as the CLR system).

Info & Guides

Why Use Clear Super Sap®? Laminating Epoxy Resin

Super Sap formulations, as opposed to traditional epoxies that are composed primarily of petroleum-based materials, contain renewable, biobased materials sourced as co-products or from the waste streams of other industrial processes, such as bio-fuels and wood pulp production. The benefits of these natural components are exceptionally high adhesion properties and excellent elongation.

Three Easy Ways to Measure Clear Laminating Epoxy Resin and Hardener

By Volume: 2 parts resin to 1 part hardener.
By Weight: Varies. Check Technical Data Sheets for specific ratio.
By Pumps: The calibrated Entropy Pump Set (sold separately) measures the exact 2:1 ratio by volume with no mess or guessing about correct measurements, so you get a proper cure every time. Pumps can be used with the 2:1 High Bio-Based Laminating Epoxy Resin (ONE), Clear Laminating Epoxy Resin (CLR), Optically Brightened Laminating Epoxy Resin (BRT), Compression Molding Epoxy Resin (CPM), and Clear Casting Epoxy Resin (CCR) systems.

Measuring & Mixing Notes: For best results, use a scale to measure the two components by weight (within 5% of the recommended mix ratio). Always mix product thoroughly for at least two minutes. To ensure complete mixing, scrape all surfaces of the container.

IMPORTANT: Clear Laminating Epoxy Resin (CLR) works better in low-humidity environments, especially when it's used outside of the recommended optimal temperature range. See specific temperature ranges in Application Tips.

Safety and Handling Information

Despite the natural derivation of Entropy resin products, exposure to these materials represents hazards typical of all epoxy resins. Exposure should be minimized and avoided through the use of proper personal protective clothing & equipment, and appropriate manufacturing controls. All persons who use, store, or transport these materials should understand proper handling precautions and recommendations, as stated in the SDS (safety data sheets).
