Sinocure Chemical Group proudly introduces AgeSin®AP-L3168 – a custom-engineered, high-performance adhesion promoter,As a specialized silane oligomer, AgeSin®AP-L3168 sets a new benchmark in coating adhesion technology, delivering superior performance across diverse applications while solving critical limitations of conventional silane-based additives.
Traditional silane coupling agents (e.g., KH-560) suffer from poor storage stability and suboptimal adhesion efficiency. AgeSin®AP-L3168 overcomes these challenges through its unique molecular design:
| Storage Stability | Poor (hydrolyzes rapidly) | Excellent (enhanced hydrolytic stability) |
| Adhesion Efficiency | Low (limited bonding sites) | High (multiple Si-O-Si bonds) |
| Compatibility | Limited resin integration | Superior (epoxy/hydroxyl groups enable seamless resin grafting) |
| Application Versatility | Narrow scope | Broad (water-based, solvent-based, plastics, glass, metals) |
Molecular Advantage:
AgeSin®AP-L3168 is a hydrolyzed silane oligomer (Si-O-Si backbone) with:
✅ Reduced reactivity (controlled methoxy group activity)
✅ Maximized bonding sites (multiple Si-O-Si bonds → higher coupling efficiency)
✅ Enhanced resin integration (terminal hydroxyl + opened epoxy groups)
AgeSin®AP-L3168 operates through a synergistic hydrolysis-anchoring-grafting mechanism:
Hydrolysis: Forms silanol groups (Si-OH) upon contact with moisture.
Anchoring: Bonds to inorganic substrates (glass, metals, pigments) via Si-O-M (M = metal/oxide).
Grafting: Integrates into organic resin matrices via epoxy/hydroxyl reactions → creates a molecular bridge.
This process ensures unmatched interfacial cohesion – critical for long-term durability in demanding environments.
*Tested: Neutral Salt Spray (ASTM B117), Impact Resistance (ISO 1518)
| Base Formula (No Additive) | 200 | 30 |
| +1% AgeSin®AP-L3168 | 500 | 50 |
*Result: 2.5× longer corrosion resistance and 67% higher impact strength vs. baseline.
*Tested: Drying Time, Hardness, Clarity, Shelf Stability
| Base Formula | 4h | 3.2 | Clear | 12 months |
| CX-100 | 3h | 4.1 | Slight haze | 2 weeks |
| AgeSin®AP-L3168 | 3.5h | 3.8 | Clear | 18 months |
*Result: Superior balance – faster drying than base, better hardness than CX-100, no shelf-life compromise.
*Tested: Adhesion on Glass (ISO 2409), Anti-Powdering on Silver-Containing Paints
| Glass | Base | 0 (Peel) | – |
| +1.5% AgeSin®AP-L3168 | 5 (No Peel) | Excellent | |
| Plastic | Base | 1 (Peel) | – |
| +1.5% AgeSin®AP-L3168 | 5 (No Peel) | No Silver Loss |
*Result: 100% adhesion improvement on glass; prevents silver flaking in metallic coatings.
