Product Details
A-318 Silicone Fluid (750 cPs Thinning Agent, 16 oz)
A-318 is a reactive dimethylpolysiloxane fluid with hydroxyl end groups, designed for use as a thinning agent in silicone elastomer systems. It effectively reduces viscosity, improving flow, workability, and processing of silicone materials.
For best performance, it is recommended not to exceed 20% by weight when blending with silicone elastomers.
