• Excellent adhesion (3M tape test shows no peeling), excellent yellowing resistance, withstands water immersion for 72 hours, resistant to cutting fluids, boil-resistant for 2 hours, withstands 5% NaOH solution, good acid resistance, hardness ≥1H (this product's special feature is its one-time UV mercury lamp curing for water immersion and boiling resistance).
• After UV curing, can be further cured by infrared heating to promote adhesion, or baked at 180 degrees Celsius for 30 minutes for better results.
• Number of functional groups: 2, curing energy: 2500-3500 mJ/cm², soluble in ketones, esters, and aromatic solvents.
• Molecular weight (Mw): 2500-3000.

Test formula: (using a 30µm wire rod)

• 2215: 90g
• 184: 0.5g
• TPO: 0.5g (can be replaced with other initiators as needed)
• NPGDA: 9g/100g (can be replaced with other monomers and resins as needed)

Note: Greater curing energy results in better water resistance. Recommended usage and storage temperature is below 25 degrees Celsius. During processing, try to avoid prolonged exposure to air or processing temperatures exceeding 40°C. Seal immediately after use for better water resistance. The less initiator used, the better the water resistance. Dissolve the initiator in monomers and cool before adding. When adding colorants, it is recommended to adjust them with monomers before adding. Prolonged exposure to air or high temperatures may reduce adhesion of this resin. The cured coating shows better water resistance after prolonged storage.
