Paint knowledge | what is inorganic zinc rich primer? Construction technology of inorganic zinc rich primer

Core tip: inorganic zinc rich primer is suitable for heavy-duty anti-corrosion primer with thick steel plate as the base material It can also be used alone, recoated and high temperature resistant Inorganic zinc rich primer can be used for long-term corrosion and rust prevention of oil tank, oil tank, cargo tank, high transmission tower, marine steel structure with harsh environmental conditions and large steel roof truss, chimney, offshore platform, chemical equipment, etc Inorganic zinc rich primer can be divided into water-based inorganic zinc rich primer and alcohol soluble inorganic zinc rich primer 1、 What is inorganic zinc rich primer? It is suitable for heavy-duty anti-corrosion primer with thick steel structure as the base material It can also be used alone, can be recoated and high temperature resistant Inorganic zinc rich primer can be used for oil tank, oil tank, cargo tank 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! All construction coatings have passed ISO9001 Home of coatings: inorganic zinc rich primer is suitable for heavy-duty anti-corrosion primer with thick steel plate as the base material It can also be used alone, can be recoated, high temperature resistant Inorganic zinc rich primer can be used for long-term corrosion and rust prevention of oil tank, oil tank, cargo tank, high transmission tower, marine steel structure with harsh environmental conditions and large steel roof truss, chimney, offshore platform, chemical equipment, etc Inorganic zinc rich primer can be divided into water-based inorganic zinc rich primer and alcohol soluble inorganic zinc rich primer 1、 What is inorganic zinc rich primer?
