Gelcoat resin is a special resin in unsaturated polyester resin industry, which can improve the appearance quality of glass fiber and reinforced unsaturated polyester resin-based glass fiber reinforced plastic products, and protect the material of the structural layer from external environmental media. In recent years, gel coat resins have received increasing attention and played an increasingly important role.
The variety of gel coat resins in my country continues to expand, and the industry is booming. The continuous improvement in the variety and performance of gel coat resins has expanded its application fields. In sanitary ware such as shower trays, bathtubs, countertops, etc., the shipbuilding industry such as yachts, lifeboats, patrol boats, etc. and transportation, construction, billboards, telephone booths and security booths have been applied.
Currently domestic gelcoat resins can be divided into o-benzene type, o-benzene (neopentylene glycol type, m-benzene type, m-benzene) neopentyl glycol type and vinyl ester type according to the matrix resin type. From the appearance color is divided into natural gel coat and color gel coat. In the production process of products, the color gel coat is required in most cases. Therefore, the color gel coat is the main force in the current gel coat resin industry. The color gel coat has stable quality, good process performance and quality assurance of the produced products. It has brand-new characteristics and is a solution in a certain sense. However, there are many processes for manufacturing color gelcoat resins, many influencing factors, and great technical difficulties, which often cause problems such as color unevenness, floating color, blooming, and inconsistency between batches.
In recent years, the annual sales of gel coats of various enterprises have been increasing by 10-30%, and the growth momentum is not decreasing. It shows that the gel coat market has great potential. As the market grows, competition pressure is also increasing. In the future, color gel coat resin is the development trend of the industry. For enterprises, it is very necessary to develop low-styrene emission gel coat resin, and it has important practical significance. Enterprises should improve the appearance quality of products and produce Color-coated gel coat
