Repairing Plastics with Insta-Weld Adhesives

Our line of Insta-Weld adhesives is specially formulated to provide maximum adhesion on a wide variety of common automotive plastics. Because Insta-Weld forms rigid bonds, it works best with rigid plastics like ABS, polycarbonate, and SMC. It may also be used to tack parts together while performing a weld repair.

Fixing Cracks Quickly and Easily

• Prior to assembling parts, lightly spray area to be bonded with 2303 Insta-Weld Activator.
• Assemble and align parts. Use clamps or 6481 Aluminum Body Tape to hold parts together while bonding.
• Apply a small amount of 2200 Insta-Weld 1 thin adhesive to the joint or crack. Optimum results are obtained with the minimum quantity of adhesive needed to fill the joint. The adhesive is thin enough to allow it to be wicked down into the crack. Use 2250 Insta-Weld 2 thick gap-filling adhesive for parts that do not fit together perfectly.
• Spray on additional 2303 Insta-Weld Activator to complete the cure. Additional Insta-Weld Activator and Insta-Weld 2 may be applied to fill any small remaining gaps.

Filling Gaps, Holes, and Gouges

• Use Aluminum Body Tape as a back-up under the hole.
• Rough sand and v-groove area around the hole and blow dust free.
• Spray a light coat of 2303 Insta-Weld Activator in and around hole.
• Fill hole with 2300 Weld Compound and saturate with a few drops of 2200-1 Insta-Weld 1. Smooth and saturate the Weld Compound with Insta-Weld using a disposable tool if desired. Wait 5 or 10 seconds and apply another light coat of 2303 Activator. The repair may be sanded or drilled immediately.
