What Heresite Protective Coatings does

Heresite Protective Coatings is a Manitowoc, Wisconsin-based manufacturer of corrosion-resistant protective coatings founded in 1935, acquired by Brazilian conglomerate WEG in 2025 and operating as a subsidiary. The company develops and produces thin-film coatings based on proprietary phenolic, epoxy phenolic, urethane, and silicone chemistries, with the flagship P-413 baked phenolic epoxy being the first HVAC-R coil coating to meet the ISO 12944-9 cyclic offshore marine standard and the only phenolic-epoxy HVAC-R coil coating to hold NSF/ANSI 51 food equipment certification. Its product portfolio spans HVAC coatings (P-413, HereShield WB-506, VR-514, P-403L, UC-5500, ES-600, HL-300) and a recently launched industrial protection line (88 HT, PAS HPD 451, SRD 501, EPX N1277, PSX HPD 371, PU N 2677) targeting metal structures, chemical processing, and wastewater environments.

Heresite serves customers across marine/coastal, mission-critical facilities (data centers, hospitals, pharmaceuticals), food processing, HVAC equipment manufacturers, and industrial/chemical processing verticals. It reports a global footprint spanning 40+ countries supported by a network of 30+ certified applicators, direct enterprise sales through custom quotes, and a direct e-commerce online store. Differentiation rests on proprietary formulations validated against demanding third-party standards (ISO 12944-9, NSF/ANSI 51), inclusion in AIA MasterSpec Section 230546, and demonstrated field performance extending coil life from 3-5 years to 10-15 years in coastal environments.

The company employs 11-50 people and operates a single manufacturing and headquarters facility at 825 E Albert Drive, Manitowoc, WI. Revenue is generated through one-time product sales (coatings sold directly, online, or through applicators) and coating application services delivered by the certified applicator network. CEO Peter Hellman has led the company through its acquisition by WEG, with the brand and product identity retained under the new parent.

Core offering

Heresite Protective Coatings manufactures and sells corrosion-resistant protective coatings for HVAC-R heat transfer equipment and industrial metal structures. The company produces a portfolio of proprietary phenolic, epoxy phenolic, urethane, silicone, epoxy, polyurethane, and polysiloxane coatings sold directly, through an online store, and via a certified applicator network. Primary products include P-413 baked phenolic epoxy, HereShield WB-506 water-based air-dry coating, ES-600 epoxy-silane, and an industrial protection line for chemical, marine, and wastewater environments.

Product overview

Heresite Protective Coatings is a manufacturer and supplier of protective coating solutions for heat transfer equipment, operating as a single product line company. The core product portfolio includes two main categories: HVAC Coatings (HereShield WB-506 water-based air-dry, P-413 baked phenolic epoxy, UC-5500, P-403L, VR-514) and Industrial Protection Products (EPX 88 HT, PAS HPD 451, SRD 501, EPX N1277, PSX HPD 371, PU N 2677). Additionally, ES-600 high-performance epoxy-silane serves as a spray-applied alternative to the immersion P-413 coating, and HL-300 hydrophilic topcoat addresses condensate management needs. The coatings are based on phenolic, epoxy phenolic, urethane, and silicone chemistries, providing corrosion protection for HVAC-R equipment in marine, coastal, chemical, wastewater, and other corrosive environments.
