As the manufacturing industry's requirements for material performance increase, polypropylene (PP) electroplating technology is favored in the automotive, electronics and packaging fields due to its lightweight and corrosion-resistant properties. However, the shortcomings of traditional materials in terms of adhesion and flexibility have given rise to the demand for innovation in flexible UV resins. The T-7050 UV resin launched by Shenzhen U-Sunny is becoming a core solution in the fields of PP electroplating, inks, adhesives, etc. due to its excellent adaptability.
1. Challenges of PP electroplating and breakthroughs of flexible UV resin
PP materials have low surface energy and strong chemical inertness, which makes the electroplating layer easy to fall off. Traditional resins have high rigidity after curing and are difficult to adapt to complex shapes or dynamic environments. T-7050 flexible UV resin solves the problem through the following characteristics:
Super strong adhesion: The molecular structure design is optimized to form a chemical bond with the PP substrate, and the peeling force of the electroplating layer is increased by more than 50%.
Dynamic flexibility: The elastic modulus is adjustable after curing to adapt to deformation requirements such as bending and stretching.
Fast curing efficiency: The UV light initiation system achieves surface drying within 3 seconds, and the production line efficiency is increased by 30%.
Chemical resistance guarantee: Passes salt spray and acid-base tests to meet the harsh environmental requirements of automotive parts.
2. Multi-scenario application of T-7050 in ink, adhesive and pressure-sensitive adhesive
2.1. High-performance UV ink
The low shrinkage and high transparency of T-7050 make it an ideal choice for PP substrate printing ink. For example:
Metallic texture ink: combined with electroplating process to achieve mirror effect, used for high-end cosmetic packaging.
Friction-resistant label: the surface hardness reaches 3H after curing, and the scratch resistance is excellent.
2.2. Environmentally friendly adhesive
PP composite bonding: replace solvent-based glue, used for seamless bonding of automotive interior PP and fabric, VOCs emission tends to zero.
High temperature resistant structural adhesive: shear strength retention rate is >90% at 80℃.
2.3. Functional pressure-sensitive adhesive
Removable design: by adjusting the cross-linking degree of the resin, repeated pasting without residual glue can be achieved, which is suitable for protective film of electronic products.
Low temperature resistance: still maintains viscosity at -20℃, and cold chain packaging labels are widely used.
