Bomar Oligomers® BR-551M

1 of 88 products in this brand

Bomar BR-551M is an oligomer that provides excellent acetone removability when used in gel polish applications. Low heat generation occurs during cure with UV/LED lamps that are typically used in nail gel polish applications. The resultant coating also has high gloss, and has low APHA color impact. Furthermore, this oligomer was designed to meet regulatory expectations for salon applications and LED curing nail polish.
