Document Type and Number:

Japanese Patent JP2004359857

Kind Code:

A

Abstract:

To obtain a lacquer type water-repellent coating composition free from problem in adhesiveness to a base material.

This water-repellent lacquer composition comprises a silicone-acryl block polymer obtained by polymerizing a monomer mixture having ≤5 reactive functional group value in the presence of an azo group-containing silicone macro initiator, an acrylic polymer having a hydroxyl group and/or tetrahydrofurfuryl group and a silicone oil and optionally further hydrophobic silica having 1-10 μm average particle diameter and being aggregate of primary particles having several ten nm average particle diameter and polytetrafluoroethylene particles having 0.2-5 μm average particle diameter. A coating film having ultra-water repellency can be obtained from the lacquer composition.
