WACKER Presents New Silicone Resin for Water-Repellent Wood Coatings
WACKER is premiering a silicone resin emulsion for wood protection coatings at Stand 1-510. Its superior impregnating effect enables long-term protection against moisture. Marketed as SILRES® WH, the product is so flexible that it even bonds to wood surfaces and thus retains the hydrophobic properties typical for silicones for many years. Long-term tests with impregnated wood show that the moisture- and damp-resistant properties of SILRES WH are fully intact after 15 years. Silicone resin additives, which have been successfully used on mineral substrates for decades, can now provide wood with lasting outdoor protection.
The 50-percent emulsion is based on a functional silicone resin and is suitable as a wood impregnant or as an additive for formulating film-forming, pigmented wood stains. Due to its hydrophobic properties, SILRES WH significantly reduces the water uptake of wood and, as a result, its moisture content. Thus, wood is better protected against typical damage caused, for example, by fungi, mold and insects or by cracks due to shrinkage and swelling. It is possible to reduce the use of biocides in formulations significantly. In wood stains and coatings, even low amounts of SILRES WH provide a long-lasting hydrophobic effect.
