Dow introduced three new-generation performance additives based on silicone chemistry  to support high durability, longer-lasting, more sustainable waterborne wood coatings.

“The most sustainable recoat is the one you don’t need,” says Isabelle Riff, Marketing Manager for Silicone Coating Additives at Dow. “Today we introduce three silicone additives that help coating formulators combine key performances required to protect and preserve the aesthetics of wood over a longer time, while meeting increasingly stringent regulatory requirements. As consumers continue to vote in wood as a sustainable, comfortable and aesthetic material for construction, furniture and interiors, the demand for innovative, high-performance and sustainable wood coating formulations continues to grow around the world.”

DOWSIL 211S Additive is a novel low-cyclic, ultra-high molecular weight silicone delivered in a waterborne system that enhances mar resistance, slip and block resistance performance. It also offers high compatibility, solvent dilution, and performs at very low dosage, Dow says.

DOWSIL 107F Additive is a low-cyclic silicone foam control agent with high effectiveness in waterborne acrylic clear wood coating varnishes, and acrylic, styrene acrylic and VAE emulsion paint for architectural wall coatings. It reduces defects and microbubbles in the coating film, thereby enhancing the durability of the substrate protection provided by the coating. Dow says it also has an excellent environmental and health profile.

DOWSIL 402LS Additive is a silicone additive which reduces the coefficient of friction of wood coatings, and offers blocking resistance, while improving the flow and levelling properties for the formulation. It performs at very low levels and exhibits a favorable environmental and health profile with no solvent, benzene, toluene, or xylene.
