Product Details

West Systems 4062 Colloidal Silica is a versatile thickening additive designed to control epoxy viscosity and prevent runoff on vertical and overhead surfaces. This fine powder creates a smooth, gap-filling mixture when combined with epoxy resin, making it ideal for structural bonding, filleting, and general laminating applications.

Key Features:

  • Thickens epoxy to prevent sagging on vertical and overhead joints
  • Creates very strong, easy-to-sand fillets and bonds
  • Produces smooth, non-textured mixtures for professional results
  • Most versatile filler in the West Systems product line
  • Mixes easily with 105 Resin and hardeners
  • Ideal for filleting, bonding, and fairing applications

Colloidal silica is the go-to thickener for boat builders, woodworkers, and composite fabricators who need a high-strength adhesive with controlled viscosity. Add gradually to mixed epoxy until desired consistency is achieved. Compatible with all West Systems epoxy hardeners. 1.9 oz container provides ample material for multiple small to medium-sized projects.
