摘要： A coating agent for a rubber-coated cylinder head gasket contains a lubricant and a urethane resin. The lubricant is unsintered polytetrafluoroethylene resin particles having an average primary particle size of 1 μm or less. The amount of the unsintered polytetrafluoroethylene resin particles in a solid content is 30 to 80% by volume. The present invention provides a coating agent for a rubber-coated cylinder head gasket that can form a coat that is highly wear-resistant under high contact pressure and high temperature conditions and with which a rubber layer is less likely to stick to the seal face of the cylinder block or the cylinder head after the use under high contact pressure and high temperature conditions, and a cylinder head gasket obtained using the coating agent.
