When coating UV resin on glass surface, low shrinkage is the key indicator to ensure the flatness and durability of the coating. This article combines industry technical data and cutting-edge product features to deeply analyze the core advantages, application scenarios and recommended products of low shrinkage UV resin to help you accurately select efficient solutions.
Core advantages of low shrinkage UV resin
Extremely low shrinkage: UV resin with a shrinkage rate of less than 3% can effectively reduce the volume change of the coating during curing, avoiding cracks or warping on the glass surface.
High transparency and yellowing resistance: UV resin with added antioxidants and 1.5 times high refractive index materials can maintain the transparency of the glass coating for a long time, avoiding yellowing problems, and is suitable for delicate scenes such as jewelry and crystal crafts.
Fast curing and strong adhesion: Some resins are designed with bifunctional polyurethane acrylates, and perform well on substrates such as glass and metal. The hardness after curing reaches more than 90D, and it is resistant to boiling water and chemical corrosion.
Application scenarios of glass coating
Decoration and crafts: High viscosity UV resin (5000-6000cps) is suitable for 3D modeling such as glass spheres and water drop effects. After curing, it forms a high gloss surface and is often used in lighting, ornaments, etc.
Industrial bonding and sealing: With its low coefficient of thermal expansion (CTE <65ppm/K) and high temperature resistance (-40°C to 150°C), the product can be used for protective coating of electronic components or industrial welding scenarios.
Jewelry and small molds: Low viscosity resin (2000cps) is easy to operate and can be used to make glass inlaid jewelry or miniature landscapes. The curing time only takes 5-10 seconds, which improves production efficiency.
Low shrinkage UV resin has become the preferred material in the field of glass coating due to its efficient curing, environmental safety and excellent performance. Whether it is Shenzhen Youyang's industrial-grade solution or U-Sunny's innovative application, the viscosity, shrinkage rate and scene requirements must be considered comprehensively when choosing. Through the products and technical parameters recommended in this article, we hope to provide scientific reference and decision-making support for your project.
