WELD-ON 16 Fast Set Acrylic Solvent Cement

A very high strength, clear, medium bodied, fast curing, bodied solvent-type acrylic cement.


WELD-ON 16 is a very high strength, clear, medium bodied, fast curing, bodied solvent-type acrylic cement. Applied to cast, molded or extruded acrylics, it will effect initial bonds within minutes and form strong joints within hours.This product may be thinned with WELD-ON 3 by approximately 10%. Initial bond forms very quickly so some parts may be handled within a few minutes of application. Bond strength continues to develop very rapidly. reaching a substantial level within hours. Joints are water and weather resistant and will generally have similar physical and chemical properties to acrylic plastic.


Parts to be joined should be clean and fit without forcing. Apply WELD-ON 16 to one or both surfaces with brush, polyethylene squeeze bottle or gun. If cement is applied to one surface, bring the two surfaces in gentle contact for several seconds to allow the dry surfaces to be softened. Assemble with firm pressure while parts are still wet. Hold or clamp assembled parts firmly until initial set. Joint strength will increase greatly in 24 hours. Thereafter, strength will continue to increase gradually for some weeks.
