In the field of industrial coating and electronic printing, applications with a single film thickness of more than 3mm pose severe challenges to material performance. The FM-350B thick film printing monomer launched by Shenzhen U-Sunny is specially designed for ultra-thick film layer processes. It provides a reliable solution for high thickness requirements through optimized rheological properties and curing stability.
Technical Challenges: The core pain points of >3mm thick film printing
Traditional monomers often face three major bottlenecks in ultra-thick film layer (>3mm) printing:
Insufficient leveling - easily leads to surface unevenness
High curing shrinkage - causes cracking or internal stress
Low drying efficiency - extends production cycle
FM-350B optimizes these key performance parameters through molecular structure innovation.
Core technical advantages of FM-350B
1. Precise rheological control
Thixotropic index adjusted to 0.85-0.92
Achieve uniform spreading under high viscosity
Support single printing thickness of 3.2-3.5mm (actual measured data)
2. Low shrinkage curing system
Crosslinking density gradient control technology
Volume shrinkage <5% (ASTM D2566 standard)
Avoid interlayer peeling risk
3. Deep curing guarantee
Transmittance increased to 88%@400nm
Ensure UV energy penetration at 3mm thickness
Shorten curing time by more than 30%
