A-315: HD Solution

A-315 Silicone Fluid (Hexamethyldisiloxane, 0.65 cSt)

A-315 is an ultra-low viscosity, volatile silicone fluid (hexamethyldisiloxane) designed to reduce surface tension and improve flow and leveling in silicone elastomer systems. This clear, essentially odorless fluid evaporates rapidly, leaving no residue behind.

Its unique properties make it ideal for enhancing surface finish, minimizing defects, and improving material handling during processing.

Product Features

• Very low viscosity (0.65 cSt) for maximum flow enhancement

• Volatile fluid that evaporates cleanly with no residue

• Reduces surface tension for improved leveling

• Promotes smooth, defect-free surfaces

• Compatible with platinum and tin-cure silicone systems

Typical Applications

• Additive for improving flow and surface finish in silicone elastomers

• Surface treatment to aid release and leveling

• Used as a wipe or mist prior to pouring silicone

• General use where fast evaporation and clean finish are required

Processing Notes

• Use in small quantities (typically ≤ 1%) when blending

• Can be applied directly to surfaces before casting

• Evaporates rapidly, leaving no residue

• Avoid high concentrations in curing systems to prevent cure inhibition
