1. The scientific working principle of silane
The general formula of silane coupling agent is Y-R-Si(OR')₃, which achieves interface strengthening through triple action:
Chemical bonding
Silanol (-SiOH) generated by hydrolysis condenses with hydroxyl groups on the surface of glass/metal/filler
Organic functional group (Y) forms covalent bond with resin (epoxy/amino/acrylate, etc.)
Directed arrangement of interface
Silane molecules migrate to the interface and self-assemble into a dense film layer (contact angle reduced by 15-30°)
Stress buffering
Flexible R group absorbs thermal stress and improves tolerance to cold and hot cycles
2. Field Application and U-Sunny Solutions
Innovative Applications in the Coating Industry
Key Technologies in the Ink Industry
Glass/ceramic inks: Using U-Sunny vinyl silane series, the adhesion reaches level 0 after UV curing (3M tape test)
PET/PP film printing: aminosilane pretreatment liquid increases the ink peeling force by 80% (dyne value>44mN/m)
Water-based inkjet: Special silane additives enable direct printing on ceramic surfaces, saving the primer process
Adhesive reinforcement solutions
Epoxy structural adhesive: Adding 3% aminosilane, the carbon fiber bonding strength is increased by 65%
Polyurethane sealant: Epoxy silane solves concrete interface failure, primer-free construction
Silicone adhesive: Special coupling agent improves the durability of anodized aluminum.
