Spraying Polyurea for Truck Bed Liners wear resistant/anticorrossion
Descriptions
a 100% solid, fast set, spray-applied, two component aromatic polyurea elastomer. The system consists of the A component, a quasi-prepolymer rich of free NCO, and the B component, a mixture of polyetheramine, amine extenders and other additives. The unique polyurea chemistry allows this material to be tolerant of moisture and lower temperatures during application. This means that high humidity and hidden moisture in concrete has minimal effect on the application of this product.
Application
Designed for use as a smooth seamless waterproof lining coating system for interior and a roof and wall coating system for exterior applications. Ideally suitable for use in areas including:Metal, concrete, wood and foam roofing.
The polyurea elastomer coating now has many advantages over the earlier developed polyurethane, polyurethane \ polyurea technology:
1. Curing speed, in the vertical plane will not produce sagging, cross-linking speed of 2-6 s, 6-9s can reach the level of non-stick hand, 30s can walk on it. 30min to put into use.
2 is not sensitive to temperature and humidity, high humidity and low temperature on the polyurea elastomer coating performance is quite small.
3 100% solid content, two-component coating, single coating system, spray coating can reach a fairly thick 2000UM above, without solvent, zero VOC.
4. Outstanding physical properties, tensile strength 14-21MPA, stretching 2% - 520% between.
5, heat resistance, thermal stability of 177 degrees, (350T)
6. Compatibility with the pigment is very good, you can adjust the color.
7. Adjustable formula, from soft to hard polymer coating.
8. Can be enhanced, in the spraying process can be added to enhance the glass fiber.
