There are several kinds of glues that are suitable for gluing plastic. What is the best glue for plastic? The type you need depends on what you want to glue. One of the most popular and effective types are weld-on glues for plastics.
J-B Weld and UV Plastic bonder are two types of welding glues. Before you start gluing any type of plastic whether it is hard plastic on your car or the plastic of a child’s toy, you should learn what type of plastic it is and choose the right glue. Each type of glue has instructions for the correct application and curing time. If you do not follow the instructions accurately, you will not get the results you want.
The most popular plastics used for commercial and residential use are polystyrene, PVC, Plexiglas, and polycarbonate. It is easy to bond the same kind of plastic together with the right adhesive, but it may be difficult or impossible to bond different types of plastic no matter what glue is used.
