LumiSet Resins™ LSR-241

1 of 3 products in this brand

LumiSet™ LSR-241 is a hydrophobic urethane methacrylate resin designed for use in top coat applications for hybrid and long-wear nail lacquers. Synthesized using building blocks from nail gel chemistries, LSR-241 is a solvent-borne film-forming resin that can offer nail lacquer formulators the benefits of impact resistance, gloss, and durability from nail gels while also achieving a tack-free finish without the need for UV or LED lamps. The combination of toughness, gloss, and hydrophobicity offers formulators an alternative to reachable plasticizers or potentially toxic gloss enhancers. Top coats formulated with LSR-241 should be paired with an adhesion-promoting base coat or base/color coat combo to ensure proper adhesion to the nail bed. LSR-241 is INCI registered and can be formulated to cure with sunlight exposure using appropriate INCI-registered photoinitiators.
