FireSkin™ 2K
Quick Overview
FireSkin 2K super-polymer is an insulating microcellular polymeric material that will withstand direct flame contact. It emits low smoke and flame spread during flame exposure making it a valuable resource for diverse fire protection enclosure applications.
It has been specially designed to coat polyurethane and polystyrene foams for fire protection. Other uses include protecting buildings, humans, animals and all nature against the destructive force of fire. Uses include deployable fire barrier systems, mobile structures, hazardous containers and specialily shielding systems for schools and apartments.
Please call or email our Technical Support Group for any questions regarding material, application or prospective uses.
Technical Application Data
FireSkin 2K is a two component 100% solids spray formulation which does not contain VOCs. This material may require the use of a primer to obtain proper adhesion. All surfaces must be clean and free of contaminates. Application temperature ranges from 20°F to 120°F. Gel Time is 8-10 sec at 75°F with full cure in 24 hours. Use standard 1:1 high pressure plural component spray machine such as Graco EXP2. Functional operation temperature ranges from -40°F to 300°F. Application spray thickness may be continuous build. Foam coverage at 60 mils thickness is 33 sq. ft./ mixed gal.

Substrate Surface Preparation
Preparation of substrate surface prior to the application of SuperSkinSystem is extremely important as durability is only as good as the weakest link in the coating system. A typical concrete substrate cleaning method is described herein.
Concrete must be fully cured and should be prepared with a sandblasting, shot blasting, diamond grinding or machine sanding depending on the severity of the concrete surface condition. Always power clean substrate with mild detergent or grease wax remover prior to any sanding or grinding operation. Similar preparation must be performed for metals to eliminate corrosion and provide a surface propfile acceptable for bonding prior to priming. Call TechSupport Group for assistance with using a SSS application system. Also read the Application Page on this website. If patching concrete, use our mineral filled fast-set Acrylic Modified Epoxy applied by trowel. For expansion joints, use Joist Seal applied by hand cartridge dispensing gun. It is always best to perform a test area section of the SSS application system prior to full scale engagement.
