Heresite UC-5500 series is recommended as a topcoat for Heresite P-413 and VR-514 series products to protect against direct sunlight exposure. This topcoat was specifically designed to protect heat transfer surfaces and related equipment.
- Thinners and Cleanup
- Heresite S-550 can be used for thinning
- Heresite S-275 or S-550 can be used for cleanup
- Coverage
Theoretical coverage is 994 square feet per gallon per dry mil. Coverage rates are estimates and make no allowance for material loss. Actual rates will vary dependent on application method, surfaces, etc.
- Surface Preparation
All surfaces must be clean, sound, and free of any oils, dirt, grease, wax and any other contamination that may interfere with coating adhesion. For best results all bare surfaces must be properly prepared and primed prior to application of this product. It is recommended to apply a primer of Heresite VR-514 or Heresite P-413.
Previously Painted Metal Surfaces: Power or hand washing is recommended to remove contamination. If oil or grease is present, a cleaner would be required — ensure cleaner is compatible with paint. Cleaner should be completely rinsed. All part to completely dry before application of product. Remove all loose coatings, rust and corrosion by scraping, sanding or sand blasting. In cases where there is a large amount of contamination, a commercial blast is acceptable in accordance with NACE #3 or SSPC-SP-6-63 specifications.
- Thinning
If applying via HVLP or conventional spray equipment, thinning may be required. A maximum of 20 fl. ounces of S-550 per gallon of combined Part A and Part B may be used. Do not exceed this recommendation otherwise performance and cure can be impacted. VOC will be impacted with the addition of S-550.
- Application
Part A and Part B are packaged in premeasured kits – with Part A being a short-filled gallon, allowing Part B to be added and mixed. The mixing ratio is 9 parts A to 1 part B. Mix Part A and Part B separately using an explosion-proof power drill and blade type mixer. Add part B to Part A and thoroughly mix and blend using an explosion-proof power drill and blade type mixer. Mix only the amount that can be used within the estimated pot life. For optimum application, air and surface temperature should be from 10 to 32°C and at least 5°F above the dew point. Above 50°C, sagging may occur.
Flush lines with an appropriate solvent. Equipment must be clean prior to start. Apply the product in even coats and maintain a wet edge. Use parallel passes with 50% overlap to avoid bare areas and pinholes. If required, cross spray at right angles. Use standard production type spray equipment (conventional, HVLP, airless, etc.).
- Cleaning Frequency
At a minimum, coils should be inspected and cleaned at least once per year. In extreme environments, where the coils are exposed to high concentrations of salt air (within 25 miles of any seacoast), or where they are installed near engine exhausts, plumbing or manufacturing vents, or regularly exposed to corrosive chemicals, you may need to clean coils more often, up to 4 times per year.
- Cleaning Process
- Turn off electrical power to the unit using lock-out system
- Flush the coil with water to rinse off loose residue. Allow the water to soak for 10–20 minutes to loosen surface residue
- Flush the coil thoroughly with any mild liquid detergent and warm water (~100°F) until all signs of residue are eliminated. If harsher cleaners are required for your environment, please contact Heresite for advice
- Rinse the unit thoroughly with clean water (it should not be brackish or contain excessive dissolved minerals)
- Allow the unit to dry completely prior to turning the electrical power on or returning the unit to service.
- Avoid
- Water under high pressure, such as a high-pressure washer. Fins may fold under high pressure causing the coating to crack
- Abrasive products or processes to scour or remove dirt
- Striking the coil with a tool to dislodge or remove soil or residue
- Corrosive, caustic or alkaline cleaners (with a pH 5.5 - 8.5) as these may permanently damage the coating and void the warranty

Safety & Health
- Caution
Contains flammable solvents. Keep away from sparks and open Flames. In confined areas workers must wear fresh air line Respirators. Persons should wear gloves or use protective cream. All Electrical equipment and installations should be made and grounded In accordance with the national electrical code. In areas where Explosion hazards exist, workmers should be required to use Nonferrous tools and to wear conductive and nonsparking shoes.
Packaging & Availability
- Packaging Type
- Packaging
UC-5500 series is available in one-gallon kits. Both Part A and Part B are provided in short-filled cans, allowing for accurate and easy mixing.
Storage & Handling
- Storage Conditions
Coating should not be stored longer than 2 years. Coating should be stored in a clean, dry environment at 50–75°F. Keep out of direct sunlight. Avoid excessive heat and keep from freezing.
