WELDON3X - Overview

SciGrip Weld-On 3 is a water-thin, non-flammable cement formulated to bond to many thermoplastic substrates, primarily acrylic. The bond is achieved by fusing the materials together with dissipation of the solvent. The initial bond forms within a few minutes and quickly increases in strength within only a few hours.

Under extreme conditions (primarily high humidity), a white mark on the plastic may appear, called "blushing." Where a more blush resistant cement and longer open time is required, SciGrip Weld-On 4 is recommended.

SciGrip 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.
