In the process of continuous upgrading of UV-curable coatings, inks and adhesives towards high-performance and functionalization, functional additives with both reactive properties and excellent silicone characteristics are becoming the key elements for achieving breakthroughs in coating performance. Our company's product, acrylic silicone oil 2220, as a compound of polydimethylsiloxane with acrylate groups as the terminal functional groups, demonstrates significant industrial application value in UV-curable coatings, inks, and the modification of high-performance resins, providing an efficient organic silicone modification solution for the development of UV-curable materials.


I. Core Structural Characteristics and Physical Properties


Product acrylic silicone oil 2220 is a yellow viscous liquid with an active ingredient content of up to 99.9%. It offers two specifications with molecular weights of approximately 2000 and 4000. This product uses acrylate groups as the terminal functional groups, with both ends of the molecular chain carrying acrylate reactive groups, belonging to a typical dual-end (dual-functional) reactive silicone material. The dual-end structure means that it can simultaneously participate in crosslinking reactions in two directions under UV light initiation, making the silicone-oxygen-silane chain segments truly become part of the resin network rather than merely being grafted on the outside of the network. Its main chain is a flexible polydimethylsiloxane structure, possessing the low surface energy, weather resistance, and flexibility of organic silicon.


II. Core Reaction Characteristics and Performance Advantages


The application value of product acrylic silicone oil 2220 is rooted in its crosslinking reaction mechanism in the UV-curable system. The essential difference brought by the dual-end structure mainly lies in stronger network stability, lower migration risk, and more significant durability improvement. In terms of performance, it shows outstanding performance in multiple dimensions: significantly improving the surface smoothness and gloss of the coating film, with long-lasting effects and no re-adhesion; within a 2% to 6% addition range, it can effectively reduce surface energy, reducing fingerprints, dust, and pollutant adhesion; the silicone-oxygen-silane chain segments have excellent UV resistance and oxidation resistance, significantly extending the coating service life; the flexible structure of the PDMS main chain enables the coating to maintain good extensibility and crack resistance in low-temperature environments.


III. Main Application Areas and Dosage Reference


Product acrylic silicone oil 2220, with its precise crosslinking modification ability, can play an important role in the following key application areas:


1. UV-curable coating system. In UV plastic paints, UV wood coatings, and UV metal coatings, this product can be used as a reactive organic silicone crosslinking modifier. Under UV light initiation, it quickly participates in polymerization, and the silicone-oxygen-silane chain segments are permanently fixed in the crosslinked network, forming a stable and durable silicone-modified coating on the surface. The recommended dosage is 0.2% to 1% for durability feel, 2% to 6% for anti-stain, and 1% to 6% for resin modification.


2. UV-curable ink. In UV printing inks and screen printing inks, this product can improve the smoothness, scratch resistance, and anti-stain properties of the ink film, improving the surface quality of printed products.


3. High-performance UV resin modification. This product can be used for the modification of UV resins such as polyester acrylate, polyurethane acrylate, and epoxy acrylate, introducing organic silicone chain segments into the resin network to improve the resin's weather resistance, durability feel, and low-temperature resistance. The specification with a molecular weight of approximately 2000 is more suitable for coating systems emphasizing leveling, surface touch, and smoothness; the specification with a molecular weight of approximately 4000 is more suitable for high-performance coating systems emphasizing durability, anti-stain, and weather resistance.


IV. Packaging Specifications and Storage Conditions


Product acrylic silicone oil 2220 is packaged in 25-kilogram plastic drums or 200-kilogram iron drums, placed in clean and dry containers, and stored in a ventilated and dry warehouse. This product is transported as a non-hazardous item. Under the conditions of proper storage and without being opened, the shelf life is one year.


V. Quality Assurance and Application Value


During the production process, the acrylic silicone oil 2220 has established a strict quality control system. Key indicators such as product appearance, active ingredients, and molecular weight are comprehensively tested throughout the process to ensure consistency and reliability between batches. As UV light curing technology continues to develop towards higher performance and functionality, the demand for dual-terminal acrylic ester functional additives that possess both reactive properties and the excellent performance of organic silicon is steadily increasing. This product, thanks to its dual functional groups, network construction ability, precise molecular weight specification design, and wide adaptability to UV systems, is becoming an important raw material option in UV curing coatings, inks, and the modification of high-performance resins. It provides strong raw material support for promoting product innovation and technological upgrading in the field of UV curing materials.
