High-energy curing UV resin (800-1000mj/cm²) has become a key material in the field of industrial manufacturing and 3D printing due to its fast curing, high precision and environmental protection characteristics. This resin achieves efficient polymerization through high-power ultraviolet light sources (such as UVA band 315-400nm) and is suitable for complex process scenarios. Leading companies such as Shenzhen U-Sunny Technology have promoted the widespread application of UV resin in the fields of automobiles, electronics, handicrafts, etc. with innovative technologies.
Core advantages of high-energy UV resin
Fast curing and efficient production
Within the energy range of 800-1000mj/cm², UV resin can be cured within seconds to minutes, significantly improving production efficiency. For example, Shenzhen Youyang's Uyracure series initiators support free radical double bond polymerization and cationic curing, which are suitable for high-precision industrial spraying and 3D printing.
Excellent physical properties
High hardness and scratch resistance: After curing, the hardness can reach 85-90 Shore D (such as high-precision resin), which is suitable for scenes that require wear resistance such as car dashboards and home appliance nameplates.
Low shrinkage: The shrinkage rate is less than 2%, ensuring the dimensional stability of precision parts, such as 3D printed figures and industrial molds.
Resistant to chemicals and high temperatures: Some resins have a thermal deformation temperature of 70-80℃, and have anti-fouling and anti-yellowing properties, suitable for harsh environments.
Environmental protection and safety
High-energy UV resin does not contain VOC (volatile organic compounds) and meets environmental protection standards.
Application scenarios and industry cases
Industrial spraying and coatings
Automobiles and home appliances: UV FLX series coatings are suitable for PC/PET substrates, with a curing condition of 800-1000mJ/cm², providing excellent concealment and overprint adaptability, and are widely used in automotive interiors and home appliance panels.
Metal substrate treatment: After matching with water-based primer, high-energy UV resin can be sprayed on the metal surface to enhance adhesion and corrosion resistance.
3D printing and precision manufacturing
Jewelry and figures: Jewelry high wax casting resin supports 180-600℃ mold-turning process, has no ash and high precision after curing, and is suitable for complex jewelry design.
Functional prototypes: Such as PRIMACREATOR series resins, which have both high toughness (fracture elongation 130%) and fast layered curing (4-12 seconds/layer), are used for wearable device prototypes.
Optics and electronics
CrystalCoat™ UV MS-HR800 and other products provide wear-resistant coatings suitable for lens and electronic component protection. The cured film thickness is 6.5-7.5 microns, taking into account both light transmittance and hardness.
