Abstract

A protective coating is provided. The protective coating comprises a synthetic resin solid content (A); and a mixture of (B-1) at least one member selected from an acetylene glycol represented by the following general formula (1): an ethylene oxide - propylene oxide block adduct of an acetylene glycol represented by the following general formula (2): and an ethylene oxide - propylene oxide random adduct of an acetylene glycol represented by the following general formula (3): (B-2) at least one member selected from a polyoxyalkylene alkyl ether having an HLB of 8 to 18 represented by the following general formula (4): - R 7 O(C 3 H 6 O) v (C 2 H 4 O) w (C 3 H 6 O) x (C 2 H 4 O) y (C 2 H 4 O) z H (4) ; and sulfur-containing surfactants represented by the following general formula (5): or general formula (6): and (B-3) water and / or a water soluble organic solvent.

Description

technical field [0001] The present invention relates to protective coatings containing acetylenic compounds, and more particularly, to protective coatings that are effective and exhibit excellent adhesion and water resistance when used in applications such as building materials, building exterior materials, and motor vehicles . Background technique [0002] Coatings are claimed to have various properties depending on the intended application of the coating. For example, protective coatings used as building materials or building exterior materials are required to exhibit good adhesion and corrosion resistance, and in some cases, high heat resistance and ability to adhere to other substrates. [0003] The building materials industry is currently undergoing a shift from conservation materials using organic solvents to conservation materials using water due to reduced use of volatile organic compounds (VOCs). [0004] However, a protective coating formed by using an aqueous re...
