4901 LamLight Fast Cure

There are other ways to make hatches, and then there’s the better way. Arjay’s Lam Light compound is used by some of country’s more innovative boat builders as that better way. It not only reduces weight and labor, but also reduces the need for extensive cosmetic work post-mold.

Better Part Cosmetics in Less Time

Lightweight LamLight cures fast and stays cool for better hatch and small part cosmetics and reduced labor costs

4901 LamLight Fast Cure Compound is formulated with premium polyester resins and advanced fillers.  It can be used as the primary laminating resin in two part compression applications for producing small parts.  The controlled exotherm and fast curing results in rapid part turnover and premium cosmetic finishes which are superior to parts made with other materials and processes.

Performance Benefits

  • Formulated with premium resins
  • Controlled exotherm and shrinkage
  • Low Styrene content
  • Very low air entrapment
  • Excellent durability
  • Can be poured, infused or sprayed

Simplify Your Process: Why LamLight is Better

Introducing Lam Light into open molds greatly reduces problems with pressure and flow when compared to RTM. This reason alone can result in lower cost, and higher quality.
