Coating classification: polyurethane intermediate coating

Core tip: polyurethane intermediate paint is mainly used as intermediate paint or flat varnish to protect steel structure or concrete in corrosive environment, such as special steel structure and engineering machinery Advantages of polyurethane intermediate coating: 1 High film thickness, high performance 2 Double filling polyurethane coating, micaceous iron in painting, iron red in painting or other colors 3 It can also cure rapidly at low temperature 4 The film is resistant to salt spray and medium acid, alkali, salt and solvent technical parameter About 60% solids Dry film thickness 50-100 μ M Theoretical Coverage Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support!
