In response to the EPA ban on Methylene Chloride, Weld-On® products formerly containing DCM and TCE have been re-formulated; Weld-On® 3, 4 and 16. Lab testing validates that the new DCM and TCE FREE products perform as well or better across all significant product characteristics, including bond strength and curing time. Your shipment may contain one or both formulations as we roll through old inventory. Thank you for understanding.

SUBSTRATE RECOMMENDATIONS:
WELD-ON 4 is formulated as a blush-resistant cement for bonding acrylic (poly-methyl methacrylate) to itself. It will also form strong bonds with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), and polycarbonate to themselves. It is not recommended for cross-linked acrylic.

BONDING RECOMMENDATIONS:
WELD-ON 4 is used extensively in sign fabrication for cementing acrylic letters to flat acrylic presentation panels and trim-capping of cut out acrylic letters. Strong butt joints are made with flat sheets by using the soak method. WELD-ON 4 is also widely used in many applications e.g. fabrication of display and presentation cases, medical equipment assembly, the bonding of plastic containers and pre-forms, and in the manufacture of numerous solvent welded structures and subassemblies using the capillary method.

GENERAL DESCRIPTION:
Weld-On 4 is a water-thin, somewhat flammable cement formulated to quickly develop very clear and high strength bonds for many thermoplastic substrates. The bond is achieved by first softening the surfaces to be joined and then fusing them together with the dissipation of the solvent.The initial bond forms within a matter of minutes and is followed by a significant and continual increase in bond strength over the next several hours. WELD-OON 4 may be preferred by some plastic fabricators because it is less likely to leave white marks (ccommonly called blushing).. For similar applications but faster setting cement, WELD-ON3 is recommended.
