Formulation Notes
Acrylic/silicone hybrid sealant for 3–6 month durability with UV protection.
Method: Add hybrid emulsion to water with gentle stirring. Add silica dispersion and UV absorber (pre-dissolved). Add surfactant and glycol ether. Add preservative. Properties: pH 7.0–8.5, translucent liquid, viscosity 200–500 cP. The acrylic/silicone hybrid binder combines the adhesion and gloss of acrylics with the hydrophobicity and flexibility of polydimethylsiloxane . Silica nanoparticles (20–50 nm) create micro-roughness on the cured film that enhances water beading (contact angle > 110°). UV absorber at 1.0% provides equivalent protection to SPF 30+ sunscreens, preventing clear-coat oxidation and fading . Application: spray and wipe; allow 24 hours for full cure before exposure to water.
