Application of Silicone Top Coat
Read Rhino Silicone Top Coat container labels, MSDS and application instructions prior to mixing. Mix 55 gallon drums and 5 gallon pails with a variable speed drill utilizing a jiffy mixer to suspend any settled pigment and attain a uniform color. Time will vary depending on temperature conditions.
Silicone Over Spray Polyurethane Foam
Rhino Silicone Top Coat should be applied to polyurethane foam surfaces between 24 and 72 hours following final application. The polyurethane foam and adjacent surfaces to be coated must be free of any degraded foam, grease, oil, dirt or other contaminants that will interfere with proper adhesion. The polyurethane foam must be completely dry and frost-free before coating. Any physical damage to the polyurethane foam must be repaired prior to any application of Rhino Silicone Top Coat. Any oxidized polyurethane foam must be repaired or replaced. Do not coat directly over polyurethane foam that has been mechanically scarified or sanded.
