  • TWO-LIQUID-TYPE EPOXY-BASED COATING COMPOSITION AND AEROSOL-TYPE EPOXY-BASED COATING COMPOSITION FOR INITIAL FIRE EXTINCTION USING CAPSULE-TYPE FIRE EXTINGUISHING AGENT
    Publication number: 20220106489
    Abstract: Proposed is a two-component-type epoxy-based coating composition and aerosol-type epoxy-based coating composition for initial fire extinction, using a capsule-type fire extinguishing agent. The two-liquid-type epoxy-based coating composition using a capsule-type fire extinguishing agent for initial fire extinction includes a main agent and a curing agent. The main agent includes 10 to 50 parts by weight of an epoxy binder, 10 to 60 parts by weight of a solvent, 10 to 50 parts by weight of a capsule-type fire extinguishing agent, 5 to 40 parts by weight of a pigment, and 0.01 to 10 parts by weight of an additive. The curing agent includes 30 to 80 parts by weight of a curing agent binder, 10 to 60 parts by weight of a solvent, and 0.01 to 10 parts by weight of an additive. The main agent and the curing agent are mixed in a volume ratio that falls within a range of 1:1 to 10:1.
