Duratec StyroShield Primer

Spray on Styrofoam to Create a Plug

Duratec® StyroShield Primer is a polyester primer that is meant to be applied directly to polystyrene foam (also known as Styrofoam). StyroShield contains microspheres that, when cured, insulate and protect polystyrene foam from the chemicals in polyester-based laminating resins, gel coat, and other Duratec products. With StyroShield, low-cost polystyrene can be substituted for urethane foam in plug, mold, and pattern-building applications.

Spray StyroShield using an HVLP gun with a 2.5 mm or larger nozzle. Apply at least 20 mils of StyroShield to ensure complete coverage and surface protection.

When in storage, the microspheres in StyroShield will float to the top and form a hard crust, so thorough mixing is required prior to use. When possible, store StyroShield Primer container upside down.

Requires 2% MEKP.
