Very Fast-Setting Solvent Cement for Bonding
WELD-ON 3 is a water-thin, non-flammable cement formulated to quickly
develop high strength, clear bonds to many thermoplastic substrates,
particularly acrylic. The bond is achieved by first softening the surfaces to be
joined and then fusing them together with dissipation of the solvent. The
initial bond forms within a few minutes and quickly increases in strength.
Substantial strength will be obtained within only a few hours. Under certain
conditions, especially with high humidity, a white mark on the plastic (commonly
called blushing) may sometimes be encountered. Where a more blush resistant
cement and longer open time is required,
WELD-ON 4 is recommended.
Weld-On 3 Acrylic Adhesive is a water thin, very fast set, solvent type adhesive
for acrylics. It also bonds other plastics such as styrene, butyrate, and
polycarbonates to themselves.
Does not bond to cross-linked acrylics.
WELD-ON® 3™ is formulated for cementing acrylic (poly-methyl methacrylate)
plastic to itself. It will also form strong bonds with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), PETG (polyethylene terephthalate glycol) and polycarbonate to themselves. It is not recommended for cross-linked acrylic.
SUGGESTED BONDING APPLICATIONS AND RECOMMENDATIONS:
WELD-ON 3 is used
extensively in sign fabrication. Strong butt joints are made with fat sheets by
using the soak method for
such applications as cementing letters to acrylic panels. Butyrate trim-capping
of acrylics is another highly recommended use for WELD-ON 3. It is also widely used in the POP industry (e.g. display), and in the
fabrication and bonding of plastic containers,
housewares, bottles and many other applications using the capillary method.
