In the process of continuous upgrading of radiation-curing coatings, inks, and varnishes towards higher speed and performance, additives that possess functions of leveling promotion, degassing and defoaming, and anti-rebonding are becoming key elements for ensuring coating quality and production efficiency. Our company's product, acrylic-modified silicone oil 2032, as a modified poly siloxane with acrylic ester groups, demonstrates significant industrial application value in areas such as flat printing inks, UV-curing inks, and screen printing inks due to its excellent flow promotion, degassing effect, and anti-rebonding properties. It provides an efficient and multi-functional additive option for the UV curing system.


I. Core Physical and Chemical Properties of the Product


Product acrylic-modified silicone oil 2032 is a grayish-green transparent liquid with an active substance content greater than 99%. At 25 degrees Celsius, its refractive index ranges from 1.4013 to 1.4106, and its viscosity is 60 to 150 centipoises. This product is a modified poly siloxane with side chains introducing acrylic ester groups, enabling it to participate in crosslinking reactions during radiation curing and being fixed in the coating network, fundamentally reducing the common migration and precipitation risks of traditional non-reactive silicone oils.


II. Core Performance Advantages


Product acrylic-modified silicone oil 2032, with its unique reactive molecular structure, exhibits the following core performance advantages in the radiation curing system:


Excellent flow promotion. It can effectively improve the flow and spreadability of coatings and inks on the substrate surface, making the coating more uniform and flat, and reducing appearance defects such as streaks and uneven coating.


Significant degassing effect. It can effectively reduce the surface tension of the system, facilitating the rapid escape of bubbles mixed during processing, reducing surface defects such as pinholes and shrinkage cavities, and improving the consistency and density of the finished product appearance.


Anti-rebonding effect. It can form a stable film on the material surface, effectively reducing surface stickiness and preventing the mutual adhesion of printed products or coatings during stacking and storage.


Crosslinkability and anti-scratch and anti-stain performance. The acrylic ester groups enable it to participate in radiation curing crosslinking reactions, effectively improving the coating's scratch resistance and marker pen resistance, and slightly increasing surface smoothness.


III. Wide Application Areas and Recommended Addition Amounts


Product acrylic-modified silicone oil 2032, with its multi-functional performance combination, can play a key role in the following radiation curing application areas:


1. Flat printing inks. It can improve ink flowability and scratch resistance, with a recommended addition amount of 0.1% to 1.5% of the total formulation.


2. UV-curing printing inks and varnishes. It can promote uniform curing, reduce bubble defects, improve flowability and degassing effect, with a recommended addition amount of 0.1% to 1.0%.


3. Screen printing inks. It can enhance membrane layer toughness and anti-rebonding performance, with a recommended addition amount of 0.1% to 2.0%.


4. Color paint and clear coat formulations. It is suitable for radiation curing color paints and clear coat systems, helping to enhance coating surface gloss and scratch resistance.


IV. Usage Guidelines and Process Recommendations


Mix thoroughly before use. The product can be added to the coating as the original form or pre-diluted form. Using the recommended solvent for pre-dilution can simplify the mixing operation. This product is suitable for addition during the grinding stage. For the lower part or when adding to clear coats, high shear conditions or pre-dilution treatment should be adopted to ensure uniform dispersion in the system.


V. Packaging Specifications and Storage Conditions


Product acrylic-modified silicone oil 2032 is packaged in 25-kilogram iron drums. It should be sealed and stored at room temperature. The shelf life is six months.


VI. Quality Assurance and Application Value


Product acrylic-modified silicone oil 2032 has established a strict quality control system during the production process. Key indicators such as product appearance, active substance content, refractive index, and viscosity are comprehensively tested throughout the process to ensure consistency and reliability between batches. With the widespread application of UV curing technology in printing, packaging, and functional coating fields, the demand for additives with multiple functions such as leveling, degassing, anti-sticking, and anti-abrasion is continuously increasing. This product, thanks to its cross-linking characteristics and comprehensive performance advantages conferred by acrylic modification, is becoming an important additive option for radiation curing inks and coatings, providing strong raw material support for promoting the improvement of product quality and process optimization in related industries.
