Instantly tacky. Sets in minutes - bonds permanently overnight. Economical to use. Special formulation dissolves a thin layer of each surface to be joined. It evaporates quickly and forms a welded joint; one as strong as the surrounding plastic. Apply with a small brush or blunted syringe-type applicator. Capillary action will spread it the length and breadth of the joint for a continuous solid weld. Plastic Weld works on most dissimilar Styrene, Butryrate, ABS and Acrylic applications.
