PlasticWeld? is a hand-mixable, fast-setting epoxy putty that forms a durable bond to most major plastic types. After mixing, it forms a polymer compound that can be molded or used to build up and repair just about anything made from plastic. When cured, it can be sawed, drilled, carved, sanded, and painted. PlasticWeld? has a 20-25 minute work life; functional cure occurs in 2-3 hours. PlasticWeld? cures to an off-white color and is rated at a tensile strength of 700 PSI. Does not adhere to polyethylene, polypropylene, or some other plastics. Test for adhesion first.
