Pur adhesive is a resilient, flexible and durable manufactured material that can take the place of paint, cotton, rubber, metal or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber or sticky like glue. So there was polyurethane glue.
Polyurethane glue is type of adhesive used in a variety of commercial industries, as well as in hobbies and crafts. Although this adhesive bears the descriptive term “polyurethane,” it has little in common with like-named finishes. However, some polyurethane glue formulations can perform as a sealant. For instance, the gel form is the type frequently used in boat and light aircraft building and repair. Other polyurethane adhesive uses include woodworking, metalwork, and masonry. Construction grade polyurethane adhesives can be used with composite decking, flooring, and concrete.
There are several advantages to using polyurethane glue over other adhesives. For one thing, it is suitable for indoor or outdoor use and is highly durable. On the other hand, the stability of polyurethane adhesive adhesive is relatively strong, and the drying speed is faster. Because the advantages of polyurethane adhesive adhesive is obvious, its application areas are also expanding, it can be used in automotive, wood, construction, packaging, book binding and so on.
Like other glues, polyurethane glue has a limited shelf life, generally six months to one year. However, it will last longer if refrigerated. It’s also worth remembering that since this type of glue reacts with moisture, it will also react to the moisture on skin. Therefore, it’s a good idea to wear gloves when working with it.
One more safety caveat: Polyurethane glue should be kept out of reach of pets and children. As with skin, the moisture-activating properties of this glue means that it can swell and cause intestinal blockage if ingested.
