Coating type (baking phenolic resin coating)


1. P-403L baking phenolic resin coating


Recommended applications: Heresite P-403L coating has good chemical anticorrosion properties and is widely used in tankers, oil tank trailers and storage tanks that come into contact with chemicals with a PH of less than 9. 


Comply with FDA: 21 CFR 175.300 is concerned with requests for direct contact with food. 


Corrosion resistance sescription: Under 49 ℃, the coating has good corrosion resistance to   92-98% sulfuric acid and most solvents, acids, brine and weak alkaline substances as well.


2. L-66L baking phenolic resin coating 


Recommended applications: Heresite L-66L coating has good corrosion resistance to a variety of acids, solvents and brine. 


In general, L-66L is a coating covering P-403L coating, and improves the release performance of the coating and prevents certain substances from invading the P-403L coating, L-66L can also be used as electricity insulated coating. 


Application objects include: Oil tank lining, blower, filter plate, tanker, oil tank trailer, air duct, exhaust hood and other industrial equipment. 


Comply with FDA: 21 CFR 175.300 is concerned with requests for direct contact with food. 


3. P-413C baking phenolic resin coating


General applications: Heresite P-413C is a highly efficient coating that is mainly used in sheet metal products that cannot be sprayed with sand on the surface. P-413C has good applicability and chemical corrosion resistance, greatly extending the service life of various products.


Main product applications: Fan housings and equipment exposed to seawater, can be widely used in barrels and drum containers.


4. P-700PC baking phenolic resin coating


General applications: Heresite P-700PC is a primer that can effectively improve coating adhesion and applicable performance. 


Main product applications: An improved baking phenolic resin primer, which is applied to a clean and skimmed surface by conventional technology. If the surface is not properly sandblasting and chemically treated, the use of the primer can improve Heresite standard coating adhesion and applicable performance. The coating is colorless and tasteless and complies with FDA regulations.




In 1935, heresite's founder Charles Hempel developed the first phenolic paint for use in metals. In 1964, heresite coatings became the first company in the world to supply coatings for aluminum fins and copper tube heat exchangers. Heresite is still the leader in the industrial coatings industry. Dongying situationTianwei Anticorrosion Engineering co., ltd. officially became the first domestic coating construction unit recognized by the United States heresite coating company on January 8, 2015. The high crosslinking density of the phenolic resin coatings produced by heresite ensures a stable heat transfer even in very thin film. At present, Tianwei Anticorrosion has successfully introduced the four main types of helst coatings, and has provided satisfactory coating protection solutions for many customers in combination with the actual situation.
