Qingdao Polyswell Technology Co., Ltd, high performance and durable polyurea manufacture
As we all know, spraying polyurea requires that the moisture content of the concrete substrate should be lower than 8%, and there should be no visible water. Why? One reason is that the adhesion of the general primer in the wet substrate is not good, even if use of wet substrate matching primer, there is a problem is that the moisture of the substrate if it is sealed inside can not come out, later due to the high temperature of the sun, water will heat into vapor, because of the volume expansion, will cause polyurea surface bulge, result in engineering quality problems.
Therefore, when we spray polyurea, we must strictly comply with the construction process requirements, and only after the base material test meets the standard can we start application, so as to ensure the quality of polyurea project.
Qingdao Polyswell is focusing on the research and development, production and sales of polyurea technology. We will always hold your back. If you have any questions about polyurea technology, please feel free to contact us.
