Acrylic series synthetic materials have good aging and water resistance properties. The water emulsion building sealant formulated with acrylic emulsion is convenient to construct and has no atmospheric pollution. It is a mid-range waterproof construction seal material urgently needed for large-scale wallboard and various light-board buildings. . The Ministry of Metallurgical Construction Research Institute and other units have been developing and applying acrylic building sealant since 1983 and passed the ministerial appraisal in October 1985. Acrylic sealing paste has excellent physical and mechanical properties, and its main technical indicators have reached the DAP standard of the United States. Now its performance, construction and engineering applications are described as follows: First, the physical and mechanical properties Acrylic sealing paste has a good construction extrusion performance, can be made of non-sagging sealant, suitable for vertical seams
