At present, the domestic and foreign solid buoyancy material water barrier layer mostly uses spraying polyurea elastomer as water barrier layer, spraying polyurea elastomer technology is a foreign nearly ten years, in order to meet the needs of environmental protection and development of a new solvless, pollution-free green coating technology, compared with the traditional low (or no) pollution coating and spraying polyurethane technology, SPUA technology has the following advantages.
① The material itself has excellent physical properties, the hardness is adjustable at will, and the feel is from soft rubber (Shao A30) to hard elastomer (SHAO D65) to meet the needs of different occasions.
② Curing fast. It can be continuously sprayed on any curved surface, vertical plane and top surface without producing flow hanging phenomenon, and the thickness requirements can be reached in one construction, which overcomes many inconveniences in multiple construction and greatly shortens the construction period. It is not sensitive to moisture and moisture, and the construction is not affected by ambient temperature and humidity.
④100% solid content, does not contain any organic volatiles, non-toxic effect, in line with environmental requirements.
⑤ Good reproduction of the base material, continuous coating, no seams, beautiful and durable.
⑥ Good weather resistance. UV resistance, cold and heat shock resistance, wind and frost rain and snow resistance, long-term use in the outdoor no powder, no cracking, no falling off.
⑦ Good adhesion. With steel, aluminum, concrete, wood and other common substrates have excellent adhesion, even if the gel time is only 3s fast system.
⑧ Has good thermal stability, can be used at 150℃ for a long time; It can withstand short-term thermal shock of 350℃.
