Abstract: Both thin and super thin fire retardant coatings are new fire retardant coatings developed in recent years. Such coatings are composed of organic resin, aerating powder, fire retardant, carbonization agent and so on. The advantages of such coatings are light weight, thin coating, and convenient construction. As a new type of fire retardant coatings, they are not yet widely used in petrochemical projects. Thin fire retardant coatings was adopted on the steel structure of CNOOC Huizhou Petrochemicals project (phase II). Combining with the construction application experiences, this paper introduces the mechanism, technical requirements and matters that need attention during construction process, aiming to provide experience and reference for similar petrochemical projects.

Key words: thin fire retardant coating, limited fire-endurance, hydrocarbon heating curve, cohesive strength
