Colorcom Group developed a new type of coating: Silicon-based coating, which is composed of silicone and acrylic copolymer. Silicon-based coating is a new kind of art coating with a certain texture by using silicone reinforced emulsion as the core film forming substance and high purity silica as the core body pigment.
1. Composition
Silicone emulsion, Silicon dioxide,
Silicone emulsion:
Acrylic acid as a high-quality raw material for coating production, has a wide range of application scenarios, silicone reinforced emulsion is based on acrylic emulsion, the use of silicone modified a kind of high strength emulsion, is a scheme to improve the comprehensive performance of coatings.
Silicon dioxide:
Silicon dioxide is a high-quality physical pigment, with strong wear resistance, high hardness, strong weather resistance characteristics, but the silica ratio is large, easy to precipitate, so the general addition amount in the coating formulation system is not too much. The amount of silica added in silicon-based coatings has been greatly increased, and its silica content can be 5 to 10 times that of ordinary coatings.
2. Technical principles
Silicone strengthening technology
The polymerization reaction of acrylic resin produces high-quality paint emulsion. Pure acrylic resin has a higher environmental protection rating, but has shortcomings such as poor water resistance, poor adhesion, high temperature tackiness, and low hardness. In order to overcome the shortcomings of acrylate, research has shown that by replacing the carbon element in the C=O double bond in acrylate with silicon element, a silicone reinforced emulsion can be obtained. Since the bond energy of the Si=O double bond is higher, the emulsion is more stable, and its weather resistance, water resistance, and adhesion can be greatly improved.
3. Advantages
Medium texture
Silicon-based coatings generally have a medium texture, visual and hand touch are obviously different from ordinary latex paint, is classified as a kind of art paint, because silicon-based paint body pigments contain a large number of inorganic mineral pigment particles, so silicon-based coatings generally have a certain metallic texture.
Clean taste and environmental protection
Since silicone-based coatings use silicone-modified and strengthened emulsions as the core film-forming substance, very little additives are used in the later coating production process, so they have a high environmental protection level and are one of the latest high-end coating varieties. Real silicone-based paint can be moved in within 4 hours after painting, and basically does not emit harmful substances into the space.
High hardness
Silicon-based coating uses silica as the core pigment, so the overall hardness of the coating film is high, the wear resistance is good, the service life of the coating film is long;
4. Construction methods
Silicon-based coating is suitable for spraying construction, because silicon-based coating has a certain granular texture, in order to ensure smooth discharge, it is appropriate to use a spray gun designed for material path and gas path separation.
5. Scope of application
Silicone-based paint is an artistic paint with a micro-texture, which is suitable for indoor space wall decoration with high environmental protection and high-grade requirements. It is especially suitable for light luxury wall decoration.
6. Industry prospects
Silicone strengthening technology belongs to the important research field of coating modification technology. At present, the application scenario is becoming more and more mature. Silicon-based coatings have the characteristics of environmental protection, clean taste, long service life, dense coating film, dirt resistance and high wear resistance, which are suitable for all kinds of home space. Through continuous technological research and development and innovation, silicon-based coatings will become one of the development focuses of the future coating market.
