A concentrated spray sealant designed for wet application on paint, glass, and plastic surfaces using foam or pump sprayer systems. Koch-Chemie Hydro Foam Sealant S0.03 ranks #1 for value among 72 spray sealants based on effective price per ounce after dilution.
Key Chemistry
pH
4.5
Active Mechanism
silicone polymer film formation
Surfactants
4 (cationic, nonionic)
Expert Analysis
The disclosed components include a methoxy-terminated siloxane polymer that forms the protective sealant film, combined with cationic and nonionic surfactants for foam generation and surface wetting. The acidic pH of 4.5 may aid in surface preparation and polymer adhesion during the wet application process.
Key Differentiators
- •Wide dilution flexibility (1:50 to 1:150) allows customization for different foam gun setups and protection levels
- •Wet application system designed to work on freshly washed, still-wet surfaces without requiring drying first
