Ips weld-on # 4 solvent acrylic cement glue 1 pint 16OZ
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.
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, fish tanks and pre-forms, and in the manufacture of numerous solvent welded
structures and subassemblies using the capillary method.
WELD-ON 4 is a water-thin 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-ON 4 may be preferred by some plastic fabricators because it
is less likely to leave white marks (commonly called blushing).
