Product Description

Entropy Resins’ SUPER SAP® 305 Compression Molding Epoxy is a versatile system designed specifically for the compression molding processes of composite parts. 305 system delivers a high bio-content, excellent fiber wetting qualities, and thixotropic characteristics to limit sag in high-temperature cure applications. A high modulus, combined with excellent elongation properties, enable durable yet lightweight composite parts. 305 is a SUPER SAP® Formulation.

Available in SLOW cure speed.

Slow Cure: 50 min pot life, recommended full cure time of 40 min at 180 degrees F / 82 degrees C.

2 Part Epoxy Kits are comprised of:
Super Sap 305 Epoxy Resin and
--CPF (FAST) or CPS (SLOW) Hardener


Best Uses

Our compression molding epoxies are SUPER SAP® Formulations for press-molding applications that utilize heat in the curing process to accelerate cycle times. Excellent elongation and adhesion to a variety of substrates along with a predictable response to heated processes make these epoxies ideally suited for press-molded composite parts such as sporting goods.

  • Skis and Snowboards
  • Skateboards
  • Press Molding Composites
  • Wood Laminates

Application Tips

  • For best results, measure the two components by weight within 5% of the recommended mix ratio.
  • Always mix the 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 you are unfamiliar with the product, create small test samples before starting a larger scale project.


Technical & Safety Data
Resin FAQ


Entropy Resins sustainable epoxies are not just made better, they’re made responsibly.


Super Sap technology reduces the impact of Entropy Resins on the environment without compromising performance.


We know that even biobased epoxy resins cause environmental impact. That's why our partner Entropy Resins conducted life cycle assessments.

More often than not, you can use heat to troubleshoot issues with 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 benefit from the addition of heat as a post-cure. Read more about why post-curing is important here.

CCR resin states it’s “water clear”, which is a reference to opacity, not "colour". That means our resin is as transparent as water, but it might have a slightly red hue.

It’s important to note that a water clear resin can impart a subtle colour over the substrate. In the case of white surfboards, you wouldn’t want any colour, so water clear may not be the best choice. However, in the case of certain wooden substrates, sometimes a bit of colour is desirable. For example, many users believe their wood looks richer after they apply ONE.

Unfortunately, there is no such thing as a resin with NO VOCs. In fact, all epoxies, resins, and polyesters emit VOCs. Read more about VOCs here.

(BC) Bio-Content is the term used to describe the level of biobased content in Entropy Resins before they are mixed with a hardener. Resin has a higher bio-content than hardener so the ratio goes down once mixed.

(MBBC) Mixed Biobased Carbon Content is the term used to describe the level of biobased content in Entropy Resins once you have mixed resin with the hardener.

Read about these two terms and our commitment to carrying more environmentally responsible products.

Entropy Resins’ Super Sap Technology replaces perto-chemical with renewable, biobased material. Entropy Resins’ is better for the planet but, we do not recommend eating directly from epoxy resin materials.

In order for epoxy (or any material for that matter) to be recommended for food contact it must be certified by the FDA. Entropy Resins is not FDA certified so we can't recommend use for food contact applications.

However when used properly Entropy Resins’ products are inert and it is possible to have your end product certified for food safety and contact. NSF certification is one such example and we've had customers' end product certified for food based applications though that method.

We used to ship 5-gallon jugs but have found that the 1-gallon jug is a better solution. Read about why we chose 1-gallon jugs here.

For live edge resins, choose CCR with CCF for pours 1” and under. Or else opt for CCR with CCS for pours 1” and over.
