HERESITE VR-514 air-dry phenolic coating is specially formulated to permit application by brush, spray or roller. Some of its outstanding properties are excellent durability, good adhesion, good film building characteristics and flexibility.
When cured, VR-514 will produce a hard, corrosion resistant film, recommended as a heavy-duty coating for exposure to splash, spillage and fumes.
Successful applications include: HVAC equipment, agricultural implements, chemical plants, canning factories, construction equipment, marine finishes, steel plants, sewage disposal plant, textile industry, underground and underwater service and ventilating systems.
VR-514 is a primer-finish combination material specially formulated for marine/salt water environments. When the finished product is going to be exposed to direct UV rays, a topcoat of Heresite UC-5500 series is recommended.
Air dry phenolic
- Recommended Uses
Heresite VR-514 is a heavy duty primer-finish combination material specially formulated for marine/salt water environments – particularly for HVAC equipment, agricultural implements, chemical and wastewater treatment plants.
If the VR-514 coated surfaces will be subjected to direct ultraviolet (UV) exposure, a spray-applied topcoat of Heresite UC-5500 series should be applied.
- Chemical Resistance
VR-514 is chemically resistant to a wide range of acids, solvents, and inorganic salts. Please review chemical resistance guide for further information.
- Packaging Information
VR-514 is available in one gallon, five gallon and 54 gallon drum quantities.
- Thinners and Cleanup
Recommended use of Heresite S-275
- 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.
VR-514 Typical Properties
- Salt Spray ASTM B-117: Passes 1,000 hours as primer finish. Passes 3,000 hours with UC-5500 topcoat.
- Dry Heat: Withstands 200°F with excursions to 250°F without damage.
- Flame Spread Test ASTM E-84: 18.4 on a scale of 0-100 (oak wood = 100)
- Smoke Density ASTM E-84: 5
- Bend Test ASTM D522: Passes ½ inch mandrel
- Meets Mil Specs: Mil-C-18468, Mil-V-1137, and Mil-V-134897
- Pencil Hardness ASTM D-3363: 4H
- Adhesion ASTM D-4541: >750 psi
- Impact Resistance ASTM D-2794: Direct >25 in/pound; Indirect 13 in/pound
- Heat Transfer: Loss less than 1% for finned tube coil applications

Solids by weight: Approximately 73%
Solids by volume: Approximately 56%
Pot life: NA
Mixing Ratio by Volume: NA 1 component
Shelf life: 2 years
Color: Red – Brown
- VOC Content
2.82 lbs/gal (338 g/L) less exempt solvents, as Supplied
- Film Thickness
For heat transfer, a 2 coat spray process will typically yield a dry film thickness of 1.5 – 2.5 mils (38 – 63.5 microns).
For use with Heresite UC-5500 series, in the event of UV exposure, apply approximately 1.5 mil (~38microns) of VR-514 followed by approximately 1.5 – 2.0 mils (38 – 50 microns) of UC-5500 series.
For all other surfaces, a typical dry film thickness of 4- 6 mils (102 – 152 microns).
- Coverage
Theoretical coverage is 900 square feet per gallon per dry mil. Coverage rates are estimates and make no allowance for material loss. Actual rateswill 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.
