Polyurea spraying is a new development in recent years. When applied to any type of foam, the coating provides a plastic-like look and feel. The coating is hard and durable, providing a rugged enclosure for any foam cutting project and protecting it from damage or weather.
The coating can be applied to any foam item, including logos, letters, logos, props and crown shapes. Polyurea coatings combine high flexibility and durability with high hardness, as well as fast drying coatings. Due to its chemical nature, it can be cured even at very low temperatures and does not require the use of a catalyst. Once covered, the foam can be sanded to a smooth or textured surface according to the customer's needs. It can also be applied to any type of coating, including water based latex, oil based coatings, and automotive coatings. This coating dries in a few minutes, providing a tough chemical and wear resistant coating with no blisters. Since polyurea dries very quickly, efficient mixing and spraying techniques are required, preferably using a spray gun.
There are other types of coatings that can be sprayed or brushed onto foams, including adhesives, waterborne resins, epoxy coatings, fiberglass, vinyl and polystyrene. However, the polyurea has a strength of about 100 times. The use of polyurea not only protects any foam project from damage; it also frees any company from buying expensive coaters worth tens of thousands of dollars.
This material is non-toxic and completely safe to use. Any type of foam can be sprayed, including rigid foams and flexible polyurethane foams. When spraying, apply a smooth and textured finish. In addition, it has many advantages, some of which include high curing speed [even at low temperatures], water resistance, moisture resistance, heat resistance, cold and sun protection, extreme wear resistance, thermal shock resistance, chemical resistance, little or no Odor, good adhesion to sprayed materials, unlimited coating thickness.
Due to the unique physical and chemical properties of polyurea, especially hard and capable of being used for isolation, many industries have recently used it extensively. Some of them include the concrete industry, flooring, roofing, bedding, tunnels, pipes, bridge coatings, can coatings and linings, ships, decorative and architectural designs. Polyurea is more than just a coating. It is also a lining and sealant with endless applications.
