Heresite Protective Coatings have been used for decades to solve corrosion problems in almost every industry. Below are some examples and a more detailed explanation of a few.
They include, Transportation Industry: Railcar, Tank Truck Trailers and ISO Tanks, Refineries and Chemical Plants: Storage Tanks, Water boxes, Pressure Vessels, Shell and Tube Heat Exchangers, Tube Sheets, Channels, and all types of Piping . Maintenance Coatings: Heresite air dry coatings are used on all types of equipment exposed to various corrosive fumes and spills. Secondary Containment: The Heresite epoxies, epoxies phenolics, and polyesters are used successfully in this service. Waste Water Treatment Facilities: Storage Tanks, Vessels, for strong acids and alkalis, Duct Work and Piping, for the most corrosive fumes such as Hydrogen Sulfide, Fans and Blowers and Maintenance Coatings. Pulp and Paper: Storage tanks and Vessels that hold the most severe chemicals, Secondary Containment and Maintenance Coatings, Tank Truck.
Heresite was the first company to apply coatings to aluminum finned copper tube coils in North America. That was over 50 years ago. Today Heresite provides the number one selling aftermarket coil coatings in the world. We have obtained this status because Heresite Phenolics are the most chemically resistant, easy to apply. The two phenolic coatings used in heat transfer equipment are P-413 heat cured phenolic applied by dip and bake procedures and VR- 500 series air dry phenolic applied by spraying techniques. Contact Heresite for our recommendation as to what coating and application technique is right for you and your corrosive environment.
Many of the Heresite Coatings are used to combat the corrosive effects of fumes from all types of sources. The Heresite baked and air dry coatings are used in many types of equipment based on their ease of application any their ability to prevent corrosion in severe atmospheres. The VR-500 series air dry phenolic and the P-413 baked phenolics are used on all sizes of Fans and Blowers, Fume Hoods, Dampers, Louvers, Grills, Duct Work etc. Heresite Coatings are used extensively in corrosive fume environments in Waste Water Treatment Plants, University Labs, Plating Facilities, and numerous Swimming Pool (chlorine < 100ppm) environments such as High Schools, YMCA, and large Water Parks.
Heresite Coatings have been trusted for many years by people in the chemical hauling business to protect their tanks from the corrosive attacks by the various chemicals that they transport. These include Tanker Trucks, Railcars and ISO tanks. Heresite coatings are well known for their ability to handle severe concentrated chemicals at higher temperatures such as 70% to 98% Sulfuric Acid, 73% Sodium Hydroxide (Caustic) at 275°F and hundreds of others.

Many of the Heresite Linings meet FDA requirements of 21 CFR 175.300 for direct food contact.
Heresite Coatings Linings have been used to protect Storage Tanks and Vessels and Pipes for over 70 years. Heresite can provide interior linings to protect the substrates from harsh chemical environments and Coatings to protect the exterior from the sun and other corrosive elements. We offer both heat cured and cold set coating and linings including phenolics, epoxy phenolics, epoxies, urethanes and polyesters. Our linings are designed for extreme immersion service with resistance to acids, alkalines, salts and water. They are resistant to high and low pH environments and most meet FDA requirements of 21 CFR 175.300 for direct food contact.
Heat Cured Phenolics are very densely cross-linked after curing. This makes it possible to apply them in a very thin coat and still get good chemical resistance. The thin coat also allows for great heat transfer. These characteristics make them ideal to protect the interior of carbon steel tubes in shell and tube heat exchangers. Heresite was the first company in North America to apply coatings to the interior of Shell and Tube Heat Exchanger tubes. This took place in 1979 and we have applied phenolics to thousands of tube bundles since then. Heresite uses the Patented Saekaphen Process developed in Germany. This process applies the coating to the tubes while the bundle is rotating on a fixture. The rotation gives even coats to each tube with no coating build up on the bottom of the tube, which happens when you spray tubes with epoxy coating. The interior coating of tubes with Heresite/Saekaphen coatings prevents corrosion damage and substantially reduces fouling. These two benefits significantly lower maintenance costs due to downtime and maintenance associated with corrosion and fouling.
