The technology of grafting acrylate modification of UV resin is becoming a research hotspot in the field of industrial coatings and materials science. Through grafting modification, UV resin has achieved breakthroughs in adhesion, wear resistance and environmental protection performance, and is particularly suitable for high value-added fields such as consumer electronics and 3D printing. This article deeply analyzes the principle of this technology, and combines Shenzhen U-Sunny and industry benchmark products to explore its practical application value.
Technical principle: How does grafting modification improve performance?
Grafting modification introduces acrylate functional groups into the main chain of UV resin through chemical bonding to optimize the molecular structure. For example, the synergistic effect of fluorosilicone molecules can significantly improve the anti-fingerprint and wear resistance of the coating (such as the super hydrophobic coating in patent CN 109749619 A), while urethane modification enhances flexibility and adhesion (refer to the high elasticity of RU-6120B-1). During the preparation process, the reaction conditions, such as the dripping rate and temperature of isophorone diisocyanate and silicone oil, need to be precisely controlled to ensure the stable performance of the product.
Application fields: Which scenarios require graft-modified UV resin?
Consumer electronics: matte touch coating
SIOResin® UV-5052 is modified with polyurethane acrylate to achieve low gloss and skin-like texture, suitable for mobile phone housing, display protection, etc.
Shenzhen Youyang's similar products can customize pH value (8-9), adapt to spraying or dipping process, and take into account production efficiency and coating uniformity.
3D printing and mold manufacturing
Standard Resin has become the first choice for mass production models due to its low shrinkage (hardness 80-85 Shore D after curing) and high precision.
The modified UV resin can further enhance the interlayer bonding, reduce the residual support structure, and optimize the post-processing process.
Optical film and industrial coatings
Epoxy soybean oil acrylate modified resin is widely used in optical film and paper coating due to its low cost and good environmental protection.
Shenzhen Youyang's UV halogen-free primer resin performs well in vacuum plating, and combined with grafting technology, it can enhance the adhesion of metal substrates.
