Duratec® StyroShield™ Primer

Duratec® StyroShield™ Primer is an air-cured polyester primer designed to be applied directly to polystyrene foam (Styrofoam™). StyroShield™ contains microspheres that, when cured, forms a barrier that protects polystyrene foam from the chemicals in polyester-based laminating resins, gel coats, tooling resins, and other Duratec® products. With StyroShield™, low-cost polystyrene can be substituted for urethane foam in plug, mold, and pattern-building applications, making prototype molds, and sealing forms for cast concrete. Duratec® StyroShield™ Primer is the perfect choice for: Making patterns from low cost polystyrene foam Making prototype molds or mold-direct construction Anchoring decorative paints onto polystyrene foam Sealing forms for cast concrete Sealing architectural fixtures 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. Thorough mixing is required prior to use. Use a drill-driven mixer or paint shaker. The crust can be mixed back into the primer. When possible, store StyroShield Primer container upside down. Requires 2% MEKP. Duratec® is a registered trademark of DURA TECHNOLOGIES INC.
