(October 22, 2026) Continuous progress has been made in the research and development of domestic silicone functional materials. Acrylic silicon oil (modified acrylic silicon oil) has seen a steady increase in applications across various fields such as light-cured coatings, electronic protection, and coating materials for new energy technologies, making it a highly significant product category within the new material industry.

Acrylic silicon oil is a grafted-modified silicone material. It contains reactive double bonds on the polysiloxane backbone, combining the advantages of both silicone and acrylic materials. Traditional silicone oils can only be used as additives; they cannot participate in the cross-linking process of paint films, resulting in problems such as insufficient adhesion between layers. In contrast, acrylic silicon oil possesses photo-curable reaction groups that allow it to form copolymer cross-links with resin systems. This ensures that the excellent weather resistance, low surface energy, smoothness, and hydrophobic properties of silicone materials are retained, while also providing the good adhesion and film-forming capabilities of acrylic resins. As a result, the flowability of paint films is improved, defects such as orange peel and pores are reduced, internal stress during curing is lowered, and the flexibility and anti-aging properties of the coating are enhanced.

In terms of application scenarios, this material can be used in various formulations including solvent-based, water-based, and solvent-free systems. In the field of UV curing, it is widely used as a fluidizing and smoothing agent in paints for wood products, plastics, and PCB circuit board inks. In high-end manufacturing applications, it can be used in photosensitive resins for 3D printing, pressure-sensitive adhesives, and optical adhesives. It helps to regulate interfacial stress and improve material compatibility. The demand in the new energy and electronics industries is particularly high; UV-wetness dual-curing three-layer protective coatings can be prepared for use in 5G communication components and battery management systems, maintaining stable insulation and moisture resistance under wide temperature ranges. Additionally, it can be used in release coatings, non-fluorinated waterproof treatments for textiles, and high-end industrial anti-corrosion protections.

With the continuous tightening of environmental policies in China, low-VOC and low-emission materials have become essential requirements in the industry, thereby increasing the market demand for environmentally friendly acrylic silicon oils. In recent years, Chinese companies have increased their research and development efforts, overcoming challenges related to high purity, low yellowing, and customized functional grades, gradually narrowing the gap with overseas high-quality products. Some domestic products have already replaced imported ones in high-reliability applications such as new energy and precision electronics. Industry data shows that the market for silicone-modified acrylic materials in China continues to grow steadily. The development of downstream sectors such as new energy vehicles, photovoltaics, and electronics manufacturing continues to drive the expansion of upstream functional silicone materials.

Technical experts in the industry indicate that current research focuses on dual-curing systems, control of nano-phase structures, and the development of low-smoke water-based acrylic silicon oils. The goal is to further enhance the thermal and humidity resistance, as well as heat shock resistance, of coatings, enabling them to meet the demands of more demanding outdoor and vehicle applications. In the future, as the support system for the silicone industry chain in China becomes more complete, customized acrylic silicon oil products will become more diverse, contributing to the upgrading of light-cured coatings, electronic packaging, and new energy protective materials in China.
