LumiSet Resins™ LSR-141

1 of 3 products in this brand
LumiSet TM LSR-141 is a urethane methacrylate polymeric resin designed for use in base and color coat applications for hybrid and long-wear nail lacquers. Synthesized using building blocks from nail gel chemistries, LSR-141 is a solvent-borne film-forming resin that can offer nail lacquer formulators the benefits of adhesion and durability from nail gels while also achieving a tack-free finish without the need for UV or LED lamps. The combination of excellent adhesion, flexibility, and toughness offers formulators an alternative to other leachable plasticizers or potentially toxic adhesion promoters. The excellent adhesion of LSR-141 allows for the combination of color and base coats into one step. Base and color coats formulated with LSR-141 should also be paired with a hydrophobic top coat due to the hydrophilic nature of LSR-141. LSR-141 is INCI registered, and can be formulated to cure with sunlight exposure using appropriate INCI-registered photoinitiators. A non-reactive alternative version of LSR-141 is available as LSR-141N.
