In the process of continuously upgrading radiation-cured coatings, wood paints, and printing inks towards higher transparency and better surface quality, high compatibility additives that possess both flow-promoting properties and anti-bubble formation capabilities are becoming the key elements for ensuring the consistency of coating appearance and re-coating performance. Our company's product, acrylic-modified silicone oil 2031, as a modified polyorganosiloxane with acrylic ester groups, demonstrates significant industrial application value in wood coatings, printing inks, plastic coatings, and varnish systems due to its excellent flow-promoting properties, high transparency in varnish, and outstanding anti-bubble formation effect. It provides a highly compatible and multi-functional additive option for UV curing systems.


I. Core Physical and Chemical Properties of the Product


Product acrylic-modified silicone oil 2031 is a light green transparent liquid with an active substance content greater than 99%. At 25 degrees Celsius, its refractive index ranges from 1.4178 to 1.4236, and its viscosity is 60 to 150 centipoises. This product belongs to a modified polyorganosiloxane and, by introducing acrylic ester groups, enables it to participate in crosslinking reactions during radiation curing. The high transparency feature makes it particularly suitable for formulation systems with strict requirements for varnish appearance.


II. Core Performance Advantages


Product acrylic-modified silicone oil 2031, with its unique reactive molecular structure and high compatibility, exhibits the following core performance advantages in radiation curing systems:


Excellent flow-promoting properties and anti-bubble formation effect. It can effectively improve the flowability and spreadability of the coating on the substrate surface, reducing bubble formation and fish-eye defects caused by uneven surface tension.


Excellent transparency in varnish. This product maintains high transparency in the varnish system, without affecting the transparency and gloss of the coating, and is particularly suitable for wood varnish and topcoats with strict optical appearance requirements.


Crosslinkability and re-coating performance. The acrylic ester groups enable it to participate in radiation curing crosslinking reactions, slightly increasing slipperiness, while having good re-coating and reprinting properties without affecting the adhesion in subsequent processes.


Non-stick property and defoaming effect. The product gives the coating surface a non-stick characteristic, preventing the printing or coating from sticking together during stacking, and also has defoaming properties.


III. Wide Application Areas and Recommended Addition Amounts


Product acrylic-modified silicone oil 2031, with its high compatibility and multi-functional performance combination, can play a key role in the following radiation curing application areas:


1. Wood coatings. It can effectively improve the leveling of varnish, reduce bubble defects, and is recommended with an addition amount of 0.05% to 0.4%.


2. Printing inks and surface varnishes. It can improve the flowability and anti-bubble formation performance of the ink, and is recommended with an addition amount of 0.1% to 1.0%.


3. General coatings and varnish systems. It can improve the uniformity and gloss of the coating surface, and is recommended with an addition amount of 0.05% to 0.3%.


4. Plastic coatings. It can improve the wetting property of the coating on plastic substrates and anti-bubble formation performance, and is recommended with an addition amount of 0.05% to 0.6%.


IV. Usage Guidelines and Process Recommendations


The product can be added to the coating as the original form or pre-diluted form. Pre-dilution with the recommended solvent simplifies the mixing operation. It is recommended to fully stir before use to ensure uniform dispersion.


V. Packaging Specifications and Storage Conditions


Product acrylic-modified silicone oil 2031 is packaged in 25-kilogram iron drums and should be stored in a sealed environment at room temperature. The shelf life is six months.


VI. Quality Assurance and Application Value


Product acrylic-modified silicone oil 2031 has established a strict quality control system during production, conducting full-process testing of key indicators such as appearance, active substance content, refractive index, and viscosity to ensure consistency and reliability between batches. With the wide application of UV curing technology in wood coating, printing and plastic coating and other fields, the demand for functional additives that possess high compatibility, excellent transparency and flow-promoting properties continues to increase. This product, thanks to its cross-linking property imparted by acrylate modification, high transparency in the varnish system and good re-coating performance, is becoming an important additive option in radiation-cured wood coatings, printing inks and plastic coatings, providing strong raw material support for promoting the product quality improvement and process optimization in related industries.
