Tech Specs
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.

Instructions
Parts to be joined should be clean and fit without forcing. Apply cement with syringe eyedropper or brush.Assemble while parts are still wet. If cement is applied to one surface let the two surfaces be in gentle contactfor a few seconds to allow the cement to soften the dry surfaces then press parts together in firm contact.For capillary method parts are placed lightly together and cement is applied to the edge of the joint with syringeor eyedropper. By capillary action the cement will flow a considerable distance (approx. ”) between two suchsurfaces. Allow a few seconds for the cement to soften the surfaces. Press parts firmly together.For soak method vertically dip surfaces until softened (approx. 2 to 5 minutes) then join pieces firmly together.Initial bonds form very quickly. Bond strength continues to develop very rapidly reaching high strength in 24 to48 hours. Thereafter strength will continue to increase gradually for some weeks.In many cases this cement dries too fast to apply by brush to the parts before they are joined.If crazing is a problem we suggest you consider annealing before cementing.
