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.
