Industry application status and technical advantages
Water-Resistant UV Adhesive for Metal/Glass is a high-performance adhesive that cures quickly through ultraviolet rays and is widely used in the automotive, electronics, aerospace and construction fields. Its core advantages are fast curing (a few seconds to a few minutes), resistance to extreme environments (-25°C to 120°C) and strong chemical resistance (acid, solvent and salt spray resistance). For example, in the automotive industry, UV glue is used to bond window glass to metal frames, significantly improving production efficiency and bonding strength (shear strength of 17.7 N/mm²). In electronic products, UV glue can achieve seamless bonding of acrylic (PMMA) and stainless steel, meeting the aesthetic requirements of precision equipment.
Waterproof and weather-resistant breakthroughs
For humid environments, products such as FIXGLASS UV 629 solve the long-term water seepage problem of glass/metal joints through high viscosity formula and multi-curing mechanism (UV light + heat activation), with water absorption rate <1.5%, suitable for bathroom equipment and underwater sensor packaging. In addition, some UV glues can maintain bonding stability for more than 5,000 hours in an environment of 85°C/85%RH, meeting the durability requirements of outdoor equipment.
U-Sunny T-7770 UV Resin: High Temperature and High Hardness Solution
Among many UV adhesive products, U-Sunny T-7770 UV Resin stands out with its unique formula. This product is designed for difficult-to-bond materials such as glass, oxidized metals and copper foil, and has the following characteristics:
High temperature resistance: It can withstand high temperatures of 150°C for a long time without powdering or cracking, and is suitable for electronic circuit board inks and automotive engine compartment components.
High surface hardness: Shore D hardness reaches 60-70, providing excellent scratch resistance, suitable for optical lens protective coating.
Environmentally friendly: Solvent-free formula, RoHS compliant, VOC emissions close to zero.
T-7770 performs well in industrial coatings and high-temperature adhesives. For example, when used for metal can printing inks, its adhesion is ≥15MPa and passes the 1000-hour salt spray test.
Innovative applications in the field of inks and pressure-sensitive adhesives
UV-curable inks: high efficiency and environmental compatibility
UV inks achieve high-precision printing on metal/glass substrates through low-energy curing technology (such as Thiol-80 formula). Taking U-Sunny's Thiol-80 as an example, it uses a 365nm UV LED light source, which consumes 40% less energy than traditional mercury lamps, and has a curing time of only 5-8 seconds, while maintaining a viscosity of 150-300cP, suitable for gravure and flexographic printing.
Pressure-sensitive adhesives: fast curing and multifunctional bonding
UV pressure-sensitive adhesives combine instant initial adhesion and long-lasting adhesion. For example, the LB-3732 model has a tack time of >24 hours at 70°C and a peel strength of >30N, suitable for aluminum foil tape and flexible circuit board fixing. Its oxygen-free curing properties (secondary curing through transparent substrates) further expand its application in sealing scenarios such as medical device packaging.
Water-Resistant UV Adhesive for Metal/Glass is driving the manufacturing industry to upgrade towards high efficiency and environmental protection. U-Sunny's innovative products such as T-7770 provide reliable solutions for industrial bonding through high temperature resistance, high hardness and wide adaptability. Whether it is precision electronics or heavy machinery, choosing the right UV adhesive will be the key to improving product competitiveness.
