The complex composition of plastic makes it very difficult to find the right type of plastic glue for it. Currently in the market today there are various types of glues available that can be used on plastic materials. The common varieties are plastic resin glue, epoxy, and super glue and hot melt glue. Below we have discussed these different varieties of glues in detail.
• Plastic Resin Glue
The common name for this poplar Plastic Glue is urea resin glue. This type of glue is widely used in wood work factories. This glue is available both in powder and liquid format. When in liquid form these glues come with a catalyst substance, while in the powdered form the glue is already formulated and can be directly mixed with water. When the powdered glue is mixed with water, the quantity of the water should be around 60% of the weight of the powdered glue. When mixing, the water should be slowly added, until a good consistency is created and the glue becomes smooth in nature. The shelf life of powdered glue is around a year and the shelf life can be decreased if the glue is stored in high temperatures or has large amount of humidity in the environment. This type of glue can be used for cold and hot press. This type of plastic resin glue has long open time which means the time taken to apply the glue on the wooden product and the time to press it. Other glues have much shorter open time. This glue can be refrigerated and is used for different types of lamination work.
This is very high strength glue and is sold to the customer in two containers. Epoxy is made when both the substances are mixed in an accurate manner. This Plastic Glue is used in automobile and airplane manufacturing industry, because it is strong and very durable. Epoxy can be used when the plastic material is heavy and has suffered great wear and tear. Epoxy also has great quality of being waterproof and is resistant to chemicals and heat. When making epoxy you need to be careful as the glue sets quickly.
• Super Glue
The other name for super glue is Cyanoacrlate. This glue works on most surfaces and only a small quantity of this glue is needed to stick the pieces of plastics. It also works on non plastic materials too. One of the best features of this super glue is that it dries very quickly and should be used to glue small pieces other than large areas. This plastic glue can be used at home when there is large amount of sticking to be done for your kids project work. But this glue should be used under supervision for your kids.
• Hot Melt Glue
This glue is used for many craft works that your children undertake. This glue is inexpensive and can be found in most stationary shops. This glue comes with a hot glue gun that melts it and makes it ready for use. Once hot the glue can be applied on a plastic layer and this would stick immediately. This hot melt glue follows the method of gluing the plastic and melts a portion of the plastic too. This creates a strong bond and the plastic gets glued. Like the super glue this hot melt glue is best suited for fixing small pieces of plastic and not over a large plastic area.
What is the process of selecting glue for your plastic?
The basic steps involved are:
• Before choosing plastic glue it becomes essential that you identify the plastic type like polycarbonate or acrylic.
• Find the accurate temperature in which the plastic can be glued. This would be between 70 degree F to 75 degree F.
• Some glue dissolves a portion of the plastic when sticking it. Thus this feature in the glue should be checked.
• Before sticking the portions of plastic, the edges could be cleaned. This would help the plastic glue better.
• Always read and follow the manufacturing instruction. Some plastic glue can be stored while other cannot.
With these essential data, you can choose your glues wisely, when you need it for your kids craft project.
