Bomar Specialties LLC Tack-Free Top Coat Oligomer

Tack-free gel polish top coats are highly desired in the nail coating industry because they provide a durable, high-gloss finish to a manicure without an IPA wipe step. Removing this step from the process saves time and allows the coating to exhibit its natural gloss. Like all nail coatings, tack-free top coats require a gloss finish, superior hardness, and most importantly, low yellowing properties. Bomar has developed a model formula using a new oligomer which provides exceptionally low colop in a tack-free top coat. The model formula requires this new oligomer, a trifunctional methacrylate monomer, a difunctional methacrylate monomer, and photoinitiatop. The formula performed exceptionally well when compared to competitor top coats in areas of yellowness, viscosity, and hardness.
