In the fields of high-end packaging, consumer electronics and automotive decoration, vacuum coating technology is rapidly replacing traditional electroplating with its metallic texture and environmentally friendly characteristics. However, the pain points such as coating shedding, complex pre-treatment and poor weather resistance have long restricted the development of the industry. The T-7130 UV resin for vacuum coating launched by Shenzhen U-Sunny has achieved a breakthrough solution of no pre-treatment and high adhesion through molecular-level structural innovation, becoming the core engine of industry upgrading.
1. Technical pain points and breakthrough innovation
Fatal flaws of traditional processes
Pre-treatment dependence:
Glass requires hydrofluoric acid etching (high pollution)
Metals rely on hexavalent chromium conversion film (carcinogenic risk)
Interface failure:
Coating bonding strength <3 N/cm (falls off after boiling water test)
High acid value resin (>15 mg KOH/g) causes electrochemical corrosion of metals.
2. Performance verification: scientific data supports reliability
1. Environmental tolerance limit challenge
Double 85 test (85℃/85%RH 1000h):
Coating bonding force attenuation <3%
Volume resistivity >3×10¹⁵ Ω·cm (to ensure the signal integrity of electronic components)
Hot and cold shock (-40℃↔85℃ 500 times):
Ultrasonic scanning shows zero delamination (SAT test)
3. Industrial application scenarios
1. High-end packaging vacuum coating
Technology revolution:
Soda-lime glass is directly coated with T-7130 primer, eliminating the hydrofluoric acid etching process
Aluminum plating bonding strength reaches 8.7 N/cm (traditional process is only 3.2 N/cm)
Case:
The yield rate of a wine packaging company increased from 82% to 99%, and the annual emission of chromium-containing wastewater was reduced by 350 tons
2. Consumer electronics decorative coating
Technical advantages:
Vacuum coating of mobile phone middle frame without sandblasting
Sweat resistance test (artificial sweat for 30 days) ΔE＜0.5
3. Metallization of automotive lamps
Reliability breakthrough:
Heat cycle resistance (-30℃↔120℃)＞1000 times
Salt spray test＞500h (ISO 9227) No corrosion
4. Technology extension and future trends
1. Green manufacturing upgrade
Water-based version VOC <10g/L, passed the German Blue Angel certification
Biological monomer replacement rate >30% (carbon footprint reduced by 55%)
2. Functional expansion
Nano-enhanced type: Add 5% ZrO₂, hardness from 2H→4H
Conductive type: Compound PEDOT:PSS, adjustable surface resistance (10³~10¹⁰ Ω/sq)
