Silicone sealant is a moisture cured product. Strictly controlling the moisture content of the material and isolating it from contact with the atmosphere during production are key factors in ensuring product quality. High load vacuum double axis mixer, vacuum kneading machine, gantry extruder, continuous automatic filling machine, and supporting synthesis, drying, and homogenization devices are the basic equipment of the production line. These devices were originally all imported, but now they can be domestically produced. The closed packaging of products has adopted domestically produced hard plastic tube automatic filling machines and aluminum-plastic composite film soft packaging machines. The manual glue injection gun, pneumatic glue injection gun, and two-component sealant automatic mixing glue injection machine used for sealing construction can be matched domestically, and the full plastic and paper plastic composite packaging materials industry can also be produced and supplied domestically. In addition, the continuous automated production line for sealant has been put into trial operation, and the world's advanced multi-component automatic metering static turbulent mixing color homogenization equipment for sealant has been put into operation on the silicone sealant production line, greatly improving production capacity, efficiency, and product quality. At present, there are at least five enterprises with production equipment capacity of over 4000 tons, which will ensure the demand for silicone sealant in construction. In addition, it is now known that multiple domestic enterprises have sold their products abroad and are beginning to explore overseas markets.

Acidic silicone sealant has excellent adhesion to glass, but it is not suitable for use in concrete, stone, and metal joints. As people's understanding deepens, its application scope will be limited. At present, neutral sealants such as alcohol and oxime removal are developing rapidly, and the functional varieties and production are constantly expanding. Among them, the market share of silicone structural sealants and glass joint weather resistant sealants has shown significant growth. New functional products such as neutral building stone sealants, anti mold sealants, fireproof sealants, metal roof and pipeline sealants have been put into the market. In addition, modified organosilicon products have begun to move from research and development to industrial production, including moisture cured sealants (POP) based on terminated siloxane alkyl polyether polymers and polyether urethane organosilicon modified sealants (sPu) terminated with siloxane. At present, the total amount of neutral sealants, including structural sealants, has exceeded 10000 tons, and the market proportion of acidic silicone sealants has begun to change.

With the development of product and building application technology, national standards and industry standards related to silicone sealant are constantly being formulated and gradually improved. In 2001, the State Administration for Technical Supervision and Inspection of China issued six product standards, including "Building Concrete Joint Sealing Adhesive", "Glass Joint Silicone Sealing Adhesive", "Stone Joint Sealing Adhesive", "Metal Color Plate Joint Sealing Adhesive", "Building Anti Mold Sealing Adhesive" and "Hollow Glass Elastic Sealing Adhesive" (JC/T 881-, JC/T 882-, JC/T 883-, JC/T 884-, JC/T 885- and JC/T 485-2001). In 2001, the National Standard Revision Plan for GB 16776 "Building Silicone Structural Sealing Adhesive" was also issued, which highlighted the functional requirements of the sealing adhesive and used indicators such as the ability to withstand joint displacement, modulus and elastic recovery rate as the technical basis for dividing product grades and uses. This will change“ Universal glue” The development of silicone sealant towards functionalization is driven by the mode .
