Formulated for Strong Interlaminar Bonds

Our #1099 High Viscosity Epoxy Surface Coat is a white, thickened epoxy material used to create the durable surface coat on room temperature epoxy molds. This surface coat can be brushed on, but spreading with a squeegee is recommended. Due to its higher viscosity, it can be applied in thicker films without developing runs or sags. It is specially formulated to provide strong inter-laminar bonds with the reinforcing materials, even if it is left unsupported overnight. #1099 resists chipping and cracking, and retains its high gloss.

• It is often chosen for broad, flat tooling surfaces where it can be applied quickly.

  • Mix Ratio (by weight) – 100:11
  • Pot Life – 20-25 minutes
  • Color – White

High Viscosity Epoxy Surface Coat quart (#1099-A) and quart case (#1099-B) kits can be shipped via standard ground service without hazard charges within the 48 contiguous United States. Both kit sizes of #1099 will be subject to a hazard charge if shipped by air. Please see our Hazardous Shipping Chart for more information about hazard fees. We will consolidate items whenever possible to minimize these fees.
