AI Technical Summary
Technical Problem
Silicone-based compounds enhance leveling properties but increase liquid repellency, leading to decreased recoatability of coating films, making it difficult to perform overcoating.
Method used
A silicone-based copolymer containing a silicone unit and a hydrophilic unit, with a fluorine content of 1% by mass or less, is developed to impart both leveling and recoatability to coating films.
Benefits of technology
The copolymer provides a cured film with excellent smoothness and recoatability, allowing for effective lamination without repelling liquid, while being fluorine-free to avoid environmental issues.
