ChemSkin™ Polyurea
Quick Overview
ChemSkin is an extremely tough, 100% solids, super-polymer formulations which stands up to high heat and provides excellent chemical resistance. ChemSkin provides excellent bonding performance, low surface friction, toughness and abrasion resistance. This unique super-polymer is designed to be applied as a fast-set spray with gel time of approximately 5-10 seconds. ChemSkin is available with flame retardants upon request. ChemSkin is a naturally caramel colored translucent coating which can be color tinted to produce translucent or opaque colors. This aromatic super-polymer is not UV stable and must be top coated with an aliphatic UV stable coating.
Technical Application Data
ChemSkin is a 100% solids mixture with no VOC’s. Application temperature ranges from 40°F – 100°F. Functional operation temperature ranges from -40° to 250°F. ChemSkin can be applied using a standard 2-component, high pressure spray machine. Substrate surfaces must be clean, dry and free of contaminates and dust. Substrates must be free of loose rust, paint, moisture, dirt oils, etc. If application surface exhibits extensive corrosion, spalling and/or weak deteriorating substrate, normal forms of media or shot blasting is recommended to create a secure surface preparation. For conditions which may only require liquid washing and cleaning with detergents, acids, bio-enzymes, etc. or conditions involving processes of scrubbing, rinsing and drying, the finish surface must not retain any residual cleaner unless specified by Superskinsystems, Inc. Concrete must be fully cured and should be prepared with shot blasting, diamond grinding or machine sanding depending on the severity of the concrete surface condition. Similar proper preparation must be performed for metal surfaces. Primers are recommended for proper preparation. Always power clean using mild detergent prior to sanding, etc. Spray coverage at 16 mils is 100 sq. ft./ mixed gallon.

Substrate Surface Preparation
Preparation of substrate surface prior to the application of a SuperSkinSystem is extremely important to achieve proper system bonding.
Concrete must be fully cured and should be prepared with shot blasting, diamond grinding or machine sanding depending on the severity of the concrete surface condition. Similar proper preparation must be performed for metal surfaces. Primers are recommended for proper preparation. Always power clean using mild detergent prior to sanding, etc. Spray coverage at 16 mils is 100 sq. ft./ mixed gallon.
