Plastic Welder™ SD (sandable) adhesive is ideal for bonding PPO, PVC, and various polyesters, polycarbonates, styrenics, and composites where filler material must be sanded to a smooth, nonporous finish. Its low-exotherm formula exhibits no expansion or foaming. Its low odor and ease of application make it a good choice for many OEM assembly operations. A structural methacrylate adhesive that requires little or no surface preparation, Plastic Welder SD also fills gaps, bonds to "green" fiberglass without sagging, and can be used to join engineered plastics to dissimilar substrates such as metals, ceramics, and wood.
