AI Technical Summary
Technical Problem
Existing antifouling paint compositions using silicone copolymers in organic solvents pose environmental and health risks due to solvent vaporization, and they lack long-term durability.
Method used
A water-dispersible resin combined with hydrophobic and hydrophilic silicone oils, where the hydrophobic silicone oil has an HLB of less than 0.5 and the hydrophilic silicone oil has an HLB of 0.5 or more, forming a coating that is environmentally friendly and long-lasting.
Benefits of technology
The composition provides excellent long-lasting antifouling properties without adverse environmental or health effects, promoting stability and uniform film formation.
