Document Type and Number:
Japanese Patent JP7216426
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide an anti-foaming agent which has excellent anti-foaming properties and does not cause cissing even when applied to a coating composition to form a thin coating film. The present invention pertains to an anti-foaming agent characterized by containing an oxidized polyethylene wax (A) and a hydrocarbon oil (B) having a kinematic viscosity (40°C) of 20-40 mm2/s. On the basis of the total weight of the oxidized polyethylene wax (A) and the hydrocarbon oil (B), the content of the oxidized polyethylene wax (A) and the content of the hydrocarbon oil (B) are preferably 1-10 wt% and 90-99 wt%, respectively. The acid value of the oxidized polyethylene wax (A) is preferably 6-20 mgKOH/g.
