RJ-WP11(E) is a silane/siloxane emulsion water repellent that is synthesized by a special process with a high-efficiency emulsifier. It is the latest generation of patented emulsion products developed by RUISIL. This product has strong permeability, which can greatly reduce the surface tension of the substrate when coated on the surface of the substrate. This product does not contain any catalyst and can be suitable for the waterproof treatment of neutral substrates such as wood.
