Polycarbonate to Polycarbonate
Dissimilar materials: Acrylic, Styrene, Vinyl, and PVC
Good joint strength
SC-325 is the simplest method of joining polycarbonate to itself or some other dissimilar materials. SC-325 polycarbonate cement has an anti-blush agent in it, but you may still experience blushing under certain conditions such as high humidity. Because of its water-thin and fast-setting characteristics, it is excellent for joining molded parts.
Preparation of the joints:
The surface to be cemented should fit accurately without forcing. The edges should be true and matched.
Capillary cementing performs best when the parts can be assembled in a jig(s). The cement is introduced into the joint by the means of an eye dropper or syringe. The joining surfaces are held under light pressure until the joint sets.
The success of a cementing job often depends in the design of the jig(s). The jig should keep the two parts firmly together, but should not force them out of shape. If the part is flexed or forced out of shape, local areas will be stressed and may cause joint failure. The pressure should be great enough to (a) Squeeze all air bubbles from the joint, (b) avoid stress concentrated at any one point, and (c) compensate for shrinkage that takes place in the joint during setting or hardening. For most joints, a uniform pressure of approximately 1 to 10 psi is satisfactory.
