WB5057 Siloxane impregnation agent

GRASi® WB5057 is a high effective moisture proof protection agent for natural wood , as pretreatment protective agent before painting on woodwork. New generation nano technology is used to produce a waterproof treatment that inhibits water absorption into the substrate. It boosts excellent water repellency. The active ingredients which is nano-size, ensuring good penetration for durability of beading effect. Prevent wood from deformation, blackening, decay etc. because of longterm damp. It also prolong wood lifespan under adverse circumstances.
