Product 170 Acrylic Modified Silicone Oil Enhances Curing Ink and Coating Upgrade


As the coating and printing ink industry rapidly evolves towards higher glossiness, scratch resistance, long-lasting anti-stain properties, and green curing, UV light curing and radiation curing systems, with their efficient and environmentally friendly characteristics and rapid curing speed, have become the mainstream in the high-end coating and printing markets. However, curing systems generally have issues such as uneven leveling, blistering of the coating, post-curing re-adhesion, poor scratch resistance, and susceptibility to marker pen stains, which seriously affect the appearance quality and service life of the finished products. Our company has launched Product 170 Side-Chain Acrylic Modified Silicone Oil, relying on the exclusive side-chain modified poly siloxane structure, it combines the characteristics of cross-linking, excellent leveling and degassing, anti-re-adhesion and anti-stain and anti-abrasion capabilities. It is a multi-functional and efficient additive suitable for radiation curing systems, various color paints, and printing inks.


Product 170 Side-Chain Acrylic Modified Silicone Oil has a grayish-green transparent liquid appearance, with an active substance content of up to 100%, no solvent addition, and pure and stable active ingredients. Its physical and chemical parameters are precisely controllable. At 25°C, the refractive index is stable within 1.4013-1.4106, the viscosity range is 60-150 cp, and the system has strong compatibility. It can be compatible with various acrylic resins, light curing resins, and color paint systems, without any adverse phenomena such as precipitation, stratification, or shrinkage. Compared to ordinary silicone oil additives, this product adopts a side-chain acrylic ester modified structure, featuring unique cross-linking reaction activity, which can participate in the cross-linking reaction of the curing system and firmly bond with the paint film, providing long-lasting and persistent performance, and will not deteriorate, migrate, or fall off with the passage of time, completely solving the drawbacks of short-term effectiveness and later failure of ordinary additives.


 1. Core Product Performance Advantages


1. Excellent leveling and degassing, eliminating coating defects
This product has excellent flow promotion and degassing effects. When added to the coating and ink systems, it can quickly reduce the surface tension of the system, help the coating and ink evenly spread on the substrate surface, eliminate brush marks, orange peel, uneven thickness, etc., and eliminate appearance defects such as pinholes and air bubble cavities. At the same time, it quickly releases the air inside the system and efficiently degases and deflates, eliminating problems such as pinholes and air bubble cavities in the coating, significantly improving the flatness and glossiness of the coating, and adapting to high-end high-gloss coating and fine printing requirements.
2. Powerful anti-re-adhesion, enhancing product stability
Ordinary cured coatings are prone to re-adhesion, sticking, and peeling in stacking, laminating, and sealed storage environments, seriously affecting the qualification rate of finished products. Product 170 has excellent anti-re-adhesion performance. After curing and forming, it can form a stable protective structure on the coating surface, effectively preventing inter-layer adhesion of the coating layer, improving the stability of finished products in stacking and storage, and adapting to large-scale industrial continuous production.
3. Cross-linkable and weather-resistant, strengthening paint film physical properties
As a reactive modified silicone oil, this product can participate in radiation curing cross-linking reactions, integrating with the resin system, significantly improving the anti-abrasion and wear resistance of the coating, reducing scratches and wear caused by daily friction and impact. At the same time, it endows the coating with excellent resistance to marker pens and graffiti, allowing surface stains and pen marks to be easily wiped without leaving traces, significantly enhancing the product's anti-stain and self-cleaning performance.
4. Optimized surface feel, adapting to high-end texture requirements
Adding this product can slightly enhance the smoothness of the coating film, making the coating surface smooth and fine, without affecting the transparency, adhesion, and subsequent processing performance of the coating film, balancing appearance texture and practical performance, and adapting to the texture upgrade requirements of high-end cultural products, electronics, and packaging printing products.


 2. Multi-Field Application Scenarios


1. Flat Printing Ink Field
Suitable for various flat printing color paints and inks, the recommended addition amount is 0.1 - 1.5%. It can effectively improve the ink leveling property, avoid uneven thickness and non-realistic dots in printing graphics, has excellent degassing and defoaming effect, eliminates printing pinhole defects, and simultaneously enhances the wear resistance and stain resistance of the printing layer, ensuring the high-definition and flatness of the printed products.
2. In the field of UV and EB radiation curing inks and topcoat oil systems, the recommended addition amount is 0.1 - 1.0%, suitable for high-speed UV curing production lines. It can solve the problems of brittle cracking, easy scratching, and easy dust adhesion of the cured coating, improve the transparency and luster of the topcoat layer, strengthen the coating structure, and extend the service life of the coated products.
3. In the field of screen printing inks
Suitable for various screen printing color inks and functional inks, the recommended addition amount is 0.1 - 2.0%. The wide addition range is suitable for different color matching and different thickness screen printing layers. It can effectively improve the leveling and spreading effect of screen printing inks, solve the problems of ink accumulation, bubbles, and back adhesion of dry plates, and improve the clarity of screen printing patterns and the qualification rate of printed products.


 Three. Scientific Use and Storage Specifications


In terms of usage process, this product only needs to be fully mixed before use, and can be directly added in the original liquid form, or pre-diluted with compatible solvents before adding to the system. To ensure uniform mixing and stable performance, it can be added during the coating grinding stage; if it needs to be added in the later clear coat stage, it is recommended to use high-speed shearing stirring or pre-dilution in advance to avoid uneven dispersion and affect the usage effect.


In terms of packaging and storage, the 170 side-chain acrylic ester modified silicone oil adopts 25kg iron drums as the standard packaging, with regular specifications, which is convenient for industrial-scale batch purchase and warehouse management. The product should be stored in a sealed state at room temperature, avoiding high temperatures, direct sunlight, and humid environments. Under standard storage conditions, the storage period can reach 6 months, with good storage stability, which can meet the regular inventory and production turnover needs of enterprises.


Currently, the domestic coating and ink industry is accelerating towards high-end, refined, and long-lasting upgrades. The radiation curing process has been fully popularized, and the market's requirements for the cross-linking stability, film formation effect, and long-term protective performance of functional additives continue to increase. The 170 side-chain acrylic ester modified silicone oil, with 100% active content, cross-linking characteristics, and multi-functional enhancing advantages, solves multiple pain points such as ink leveling differences, foaming, back adhesion, weak scratch resistance, and easy staining of ink and coatings, is compatible with mainstream printing and curing coating systems, and has outstanding cost-effectiveness and practicality. In the future, this multi-functional modified silicone oil will continue to help the printing and coating industries improve efficiency and quality, providing core raw material support for the innovative upgrade of high-end inks and environmentally friendly curing coatings.
