Polyurea spray coating is a new development in recent years. This coating provides a plastic-like look and feel when sprayed over any type of foam. The coating is hard yet durable, providing a strong cover for any foam cutting project and protecting it from breakage or weather damage.
This coating can be applied to any foam project including signs, lettering, logos, accessories, and crown molding. Polyurea coating combines high flexibility and durability with high hardness, and is a fast-drying type of coating. It can be cured even at very low temperatures due to its chemical properties, and it is not necessary to use a catalyst. After being coated, the foam can be sanded to a smooth or textured finish, depending on customer needs. It can also be painted with any type of paint, including water-based paint such as latex, or oil-based paint, as well as automotive paint. This coating dries in minutes, providing a coating resistant to abrasion and harsh chemicals, without blisters. Since polyurea dries very quickly, it requires efficient mixing and spraying techniques, preferably using a spray gun.
There are other types of coatings that can be sprayed or brushed onto foam, including adhesive glue, aqueous resin, epoxy coating, fiberglass, vinyl, and polystyrene. However, polyurea is about 100 times stronger. Using polyurea will not only make any foam project tear resistant; It will also save any business from having to purchase an expensive coating machine costing tens of thousands of dollars.
This material is non-toxic and completely safe for use. Any type of foam can be sprayed, including rigid foam and soft polyurethane foam. Spraying can apply both a smooth and textured finish. In addition, it has many advantages, some of them include high curing speed (even at low temperatures), water resistance, protection against humid, hot, cold and sunny conditions, extreme abrasion resistance, thermal shock resistance, chemical resistance. , little or no odour, good adherence to the material on which it is projected and unlimited application thickness.
Due to the unique physical and chemical properties of polyurea, especially being tough and capable of serving as insulation, there are many industries that have recently made great use of it. Some of them include the concrete industry, floors, roofs, bedliners, tunnels, pipes, bridge lining, tank lining and lining, marine, decorative and architectural designs, among others. Polyurea is much more than a simple coating. It is also a coating and a sealer with endless applications.
