CONDENSATION CURABLE COMPOSITION
20230127458 · 2023-04-27 ·

A moisture-curable composition is shown and described herein. The moisture-curable composition comprises a moisture-curable resin and a moisture scavenger selected from a cyanoalkylalkoxysilane. The inclusion of the cyanoalkylalkoxysilane in the moisture-curable composition has been found to effectively scavenge moisture and control the rate of curing and viscosity increase in the composition.

Coating compositions and coatings with improved soiling resistance and (self-)cleaning properties are disclosed. The coating compositions and coatings may be nonaqueous coating compositions and may include at least one hydroxyl group-containing compound, at least one isocyanate group-containing compound having free or blocked isocyanate and silane groups, at least one catalyst for the crosslinking of the silane groups, and at least one alkoxysilyl-functional siloxane.

Polysiloxane resin composition

A composition which provides a coating film having excellent foul releasing property is disclosed. The composition comprises, based on the solid contents of the composition: (A) 20 to 80 weight % of a resin which has a polydialkylsiloxane unit and an epoxy resin unit within its structure; (B) 0.1 to 5 weight % of an amino silane; (C) 0.5 to 5 weight % of a hydrophilic additive; and (D) 0.1 to 5 weight % of a catalyst. A coating, e.g. a coating film, formed from the composition generally has an amphiphilic surface. Thus, the composition is suitable for coatings which prevent both hydrophobic and hydrophilic fouling.
