Product Details

This is a water thin, non-flammable, very fast-setting solvent cement for gluing or bonding acrylic. It will also bond with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), PETG (polyethylene terephthalate glycol) and polycarbonate to themselves. It will not bond to cross linked acrylics and does not work on mirrored acrylics. The technical term to describe it would be an acrylic adhesive but commonly it might be referred to as an acrylic glue. Please note that this is the same as IPS Weld-On 3.

Directions for use:

GENERAL: Surfaces to be joined must be clean, dry, and fit intimately 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 contact for a few seconds to allow the cement to soften the
dry surfaces, then press parts together in firm contact. Initial bonds form very quickly. 65 – 80% of the ultimate bond strength will be obtained within
24 hours. Strength will continue to increase for several weeks.

CAPILLARY METHOD: Parts are placed lightly together and cement is applied to the edge of the joint with syringe or eyedropper. By capillary action,
the cement will flow a considerable distance, approximately 0.25 inch (0.64 cm), between two such surfaces. Allow a few seconds for the cement to
soften the surfaces. Press parts firmly together.

SOAK METHOD: Vertically dip surfaces until softened (approximately 2 to 5 minutes), then join pieces firmly together.
• 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.
