Weld-On #3 Cement, DCM & TCE Free Formula, Gallon and Weld-On Applicator Bottle with Needle (Pack of 4)

Weld-On #3 is a fast-acting, water-thin solvent cement designed specifically for bonding acrylic (plexiglass) and other compatible thermoplastics with clean, nearly invisible seams. Formulated without DCM or TCE , this safer alternative delivers strong capillary bonds while meeting modern environmental and workplace safety standards — making it a preferred choice for fabricators who want performance without the harsh chemistry. The natural, low-viscosity formula flows effortlessly into joints through capillary action, creating a solvent weld that becomes part of the material itself. This pack of four gallons, each paired with an applicator bottle and needle, is ideal for high-volume shops, production environments, and busy fabrication studios working with acrylic displays, signage, aquariums, retail fixtures, optical components, and architectural glazing. The applicator bottle and needle tip offer precise, controlled application — minimizing waste and keeping work surfaces clean. Industries ranging from point-of-purchase display manufacturing to museum case construction rely on Weld-On #3 for its consistent, professional results on straight butt joints, mitered edges, and laminated assemblies. For high-performance results, ensure mating surfaces are cleanly cut, polished, and free of dust or oils before applying. Capillary bonding works high-performance when parts are held in position first, with the solvent introduced along the joint line to draw inward naturally. Allow adequate cure time before handling or stress-loading the bond. Stocked and ships from West Nyack, NY.
