AI Technical Summary

⚠Technical Problem

Existing UV-curable coatings suffer from decreased transparency when improving hydrophobicity and use petroleum-based raw materials, resulting in environmental pollution. There is a lack of hydrophobic and antifouling coatings with high light transmittance and low pollution.

⚗Method used

By utilizing the synergistic effect of cashew phenol and fluorinated acrylic acid, cashew phenol-based UV-curable monomers, fluorinated hydroxyl acrylate polymers, and cashew phenol-based polyurethane acrylic coatings are prepared. These are then cured under UV irradiation using a photoinitiator to form a hydrophobic and antifouling coating.

🎯Benefits of technology

The prepared coating has good light transmittance, hydrophobicity and self-cleaning properties, which reduces environmental pollution and reduces costs by utilizing the renewable resource cashew phenol.
