Air Dry Phenolic Coatings

PRODUCT SPECIFICATIONS:

GENIC TYPE: Air drying phenolic. RECOMMENDED USAGE: VR-500 air dry phenolic series coatings are specially formulated to permit application by brush, spray or roller. Some of their outstanding properties are: excellent durability, good adhesion, good film building characteristics and flexibility.
When thoroughly aged, they produce hard corrosion resistant films. Recommended as a heavy duty maintenance coating for exposures to splash, spillage and fumes. Successful applications include: agricultural implements, chemical plants, canning factories, construction equipment, marine finishes, steel plants, sewage disposal plant, textile industry, underground and underwater service, and ventilating systems. The VR-514 brown coating is a primer-finish combination material, specially formulated for salt water service. When finished product is going to be exposed to UV rays, one topcoat of UC-5500 polyurethane is recommended. Allow the VR-500 to dry 24-48 hours before applying the UC-5500 coating

VISCOSITY: (depends on color) Finish: 56-96 K.U. (Krebs Units) Primer: 88-98 K.U. (Krebs Units) TEMPATURE LIMITATION: VR-500 accepts dry heat temperatures up to 0ºF (93ºC) COLORS VR-500 Clear VR-502 Black VR-504 Brown VR-506 Gray VR-508 Ivory VR-509 Machine Gray (Other Colors Available On Special Order)
COVAGE: Theoretical coverage - 737 sq. ft per gal. at 1 mil. Recommended total dry film thickness is 4 to 6 in a 2 to 3 coat system. (At 5 mils DFT average coverage would be 118 sq. ft. per gallon). This includes a % loss factor.
SURFACE PREPARATION: Remove all oil, grease from the surface with an appropriate solvent, such as HJ-0362.
STEEL: (NON-IMMSION) a commercial blast is acceptable in accordance with NACE #3 or SSPC-SP-6 specifications. Surface profile or anchor pattern shall be -25% of the recommended dry film thickness.
CONCRETE: (NON-IMMSION) Remove protrusions by stoning, sanding or grinding. Concrete must be cured at least 28 days @ 70ºF (21ºC) and 50% humidity. Surfaces must be acid etched or abrasive blasted to remove laitance.
Non-Immersion - Surfaces must be acid-etched or abrasive blasted to remove laitance.
PRIM: While VR-500 Series are self-priming on steel, four primers are available.
VR-502P, VR-504P, VR-506P are inhibitive primers to be used for maximum corrosion resistance.
VR-508P is a primer for use in food service areas, on concrete or porous substrates.
On concrete or porous surfaces, two (2) coats of primer with two (2) coats of finish are recommended. The first coat shall be thinned one (1) part primer to one (1) part
HJ-333 solvent.
THINN: Recommend use of HJ-111 solvent for spray and HJ-333 solvent for brush or roller application.
THINNING: The amount of thinner required is dependent upon temperature, ventilation, humidity; spray equipment used and desired film thickness.
SPRAY: VR-500 series coatings are normally diluted 10 to % with HJ-111 solvent depending on equipment and operators desired viscosity
BRUSH OR ROLL: (non-porous surfaces) VR-500 series coatings may be applied without dilution. If desired, a small amount of HJ-333 solvent may be used.
APPLICATION:
1. Do not apply if temperature is less than 5ºF (2ºC) above dewpoint or if temperature is below 45ºF (7ºC).
2. All spray equipment shall be thoroughly cleaned and the hoses in particular shall be free of old paint film and other contaminants.
3. Use standard production type spray guns:
May also be used with airless spray equipment.
4. Air supply shall be uncontaminated. Adjust air pressure to approx. 50 lbs. at the gun and provide 15-% pot pressure. Adjust spray gun by first opening liquid valve and then adjust air valve to give approx. an 8"-12" fan, holding gun perpendicular to the surface at a distance of 12".
5. Apply a mist bonding pass.
6. Allow to flash off for several minutes, but not long enough to allow film to completely dry.
7. Apply 3-4 criss-cross multi-passes maintaining a wet appearing film approx. 3-4 mils wet film thickness equals approx. 1.5 mils dry film thickness.
8. Air dry with ventilation.
CURING SCHEDULE:
AIR DRY: Recoat in 24 hrs @ 70ºF (21ºC)
FULL CURE: 7 TO 14 DAYS
FORCE CURE: mins. per coat @ 250ºF (121ºC).
CLEAN UP: Use HJ-111 solvent.
STORAGE: Coating should not be stored longer than 24 months. Storage at 80ºF (27ºC) may shorten shelf life.
