SNK-9203(Polyester Acrylate)
UV Metal Adhesion Resin(Polyester acrylate) SNK-9203
Product Description:
Main applications: This product is suitable for glass, metal, and etching ink (alkaline wash) applications. It can perform alkaline washing with a 5% NaOH solution at 30°C for no more than 5 minutes. It can also be used for cover plate ink, as well as for bonding between glass or between glass and aluminum alloy.
Process: Screen printing, roller coating, spraying, adhesives, etc. It is miscible with conventional UV monomers and resins.
Typical performance characteristics:
- Excellent adhesion (3M tape test shows no peeling), good water resistance, high cost-performance ratio, excellent yellowing resistance, resistant to cutting fluid for ≥0.5 hours, hardness ≥1H.
- Alkaline washing speed and water resistance can be adjusted with trifunctional or higher monomers or resins. UV curing can be followed by infrared heating to enhance adhesion.
- Number of functional groups: bifunctional, curing energy: 500-800 mJ/cm², soluble in ketones, esters, and aromatic solvents.
- Molecular weight (Mw): 1500-2000.
