As we all know, “foam caulking agent” is a product invented in Germany and is mainly used In the field of building doors and windows. Shanghai Weigu Chemical Products Co., Ltd. was invested and established by a German-funded enterprise. It established a factory in Shanghai, China in 1996 and became a domestic manufacturer of foam caulking agents. It introduced foam caulking agent production technology into the country and promoted it. Many domestic construction companies had not used foam caulking agents before Weigu entered the Chinese market. Weigu led the engineering and construction industry in using foam caulking products because this product is aNew, environmentally friendly, energy-saving building materials, has good sealing, sound insulation, waterproof and other properties, Therefore, many buildings have begun to use foam caulking products.
However, before2004, there was no domestic product standard for foam caulking agents, and product quality was uneven. Therefore, in 2004, Henan Building Materials Research Institute and Shanghai Jianke The institute took the lead in formulating the industry standard “JC 936-2004 One-component polyurethane foam caulking agent” with reference to Weigu’s corporate standards. The products produced by Weigu using European technology not only comply with “JC 936-2004 One-component polyurethane foam caulking agent”, but also meet the more demanding German DIN 4102 German construction industry standards. Weigu’s high requirements for product quality are gradually being replaced by high-end Engineering manufacturers are especially recognized for landmark buildings. Landmark buildings pay more attention to product quality when using foam caulks and are more likely to specify the WAG brand.
