ChemSkin™ Silicone Polyurea (CSP)

Available in stock

Quick Overview

CSP is a patented 100% solid silicone modified polyurea. The silicone modification increases chemical resistance, lowers water absorption, improves UV resistance and has higher HDT. The CSP also meets the NSF-61 requirement for potable water.

US Patent #: 9,714,363

Technical Application Data

ChemSkin Polyurea (CSP) does not contain VOC’s. Application temperature ranges from 40°F – 100°F. Functional operation temperature ranges from -40° to 250°F. CSP may be applied by 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.


A geotextile material is soaked with water and then sprayed with CSP. The CSP displaces the water and sets up as if it was never wet.

Water pipe using CSP with NSF-61 approval.
