Scalecoat Probond professional liquid plastic welder is designed for use with plastic models. This solvent-type cement uses capillary action to weld styrene, acrylic, butyrate and ABS plastic. To apply, place the parts together and then put a drop on the seam. Hold for 10 seconds. In that amount of time, Probond bonds and starts to cure. This method is far superior to thicker plastic cement which is messy, harder to control and can damage expensive model kits. Probond comes in a two fluid ounce bottle and includes an applicator brush built into the bottle cap.
