Unisil Fiber Bulking Agent
Unisil Fiber Bulking Agent can be used to thicken silicone coatings into brushable mastics.
Thicker materials allow for fabrication of cants and filling around irregular surfaces. Excellent for flashing details, metal roof seams, inside and outside flashing details, round stacks, pipe legs, pitch pockets, conduit pipes, expansion joints, etc.
Unisil Fiber Bulking Agent is a soft, flexible high-tensile polyethylene fiber used as a general thickener to increase tensile strength and reduce sag for Unisil or Unisil HS silicone coatings.
