ALSAN® COATING SIL 402 SKU: L-SILWH5

 

ALSAN Coating SIL 402 is a VOC compliant, high solids, single component, silicone roof coating and protective barrier for a variety of low slope roof surfaces and substrates. Upon cure, ALSAN Coating SIL 402 forms a durable, weatherproof coating that is highly resistant to degradation from UV and natural weathering. ALSAN Coating SIL 402 may be applied as a maintenance coating over sound and dry single ply (TPO, PVC, EPDM, and CSPE), modified bitumen, BUR, metal roofing and/or other approved existing coatings.

  • Technology Silicone

Installation

ALSAN Coating SIL 402 can be applied using a single component airless spray equipment, a roller or a brush. Prior to starting the application, perform an adhesion test on each surface type to ensure adequate bond can be achieved or if a primer or other specific surface preparation is required. Assure ambient and substrate temperatures remain 40°F (4.4°C) or above, to assure proper application and curing.

NOTE: ALSAN Coating SIL 402 reacts with atmospheric moisture to cure. Once containers are open and exposed to the atmosphere, a skin will form on the material over time, which must be removed from the bulk material before use. Coverage rates are based on a maximum 2:12 slope if applying ALSAN Coating SIL 402 on a higher slope, it will be applied in multiple thinner coats to achieve same desired coverage rate.

Please refer to the SOPREMA Roof Coatings Technical Manual for additional application guidelines.
