SCIGRIP® Weld-On 3 Acrylic Cement 1 Pint

Weld-On 3 is a very fast, clear, water thin, non-flammable, high strength, solvent-type acrylic cement. The bond is
affected by softening the surfaces to be joined and fusing them together. An initial bond will be formed within a
few minutes and its strength will increase rapidly. Substantial strength will be obtained within a few hours. Under
certain conditions, especially with high humidity, this cement may leave a white mark on the plastic (commonly
called blushing). For a more blush resistant, but somewhat slower acrylic cement, we suggest you try Weld-On 4
or 5.

SUBSTRATE RECOMMENDATIONS

WELD-ON 3 is formulated for cementing acrylic plastic to itself. It will also form strong bonds with other plastics
such as styrene, butyrate and polycarbonate to themselves. It will not bond to certain cross-linked acrylics.

BONDING RECOMMENDATIONS

WELD-ON 3 is being used by sign companies for cementing letters to acrylic panels. Strong butt joints are made
with flat sheets by using the soak method. Butyrate capping is cemented to cutout acrylic letters. It is being used
in industries for display items, plastic containers, housewares, bottles, etc.
