ProvectuPel® 791
Advanced Polymer · ProvectuPel®
ProvectuPel® 791 is a reactive silane/siloxane emulsion containing M, D, T, and Q units, developed as a high-performance hydrophobic additive for waterborne paints, stains, primers, and coatings. It imparts durable water repellency, prevents water staining, and provides wear resistance while maintaining color stability with non-yellowing performance. Highly compatible with waterborne resins, it ensures recoatability and vapor permeability, making it ideal for long-lasting protection. In addition to use as an additive, ProvectuPel® 791 can also be applied as a standalone sealer for wood, composites, masonry, stucco, and concrete surfaces.
