Polyester Urethane is a multi-use, two-component product that provides excellent gloss and color retention, as well as superior abrasion, chemical, and solvent resistance. It may be used anywhere a performance urethane is necessary for interior or exterior applications. Excellent flow and leveling. It is ideal as a floor finish for commercial and industrial applications as well as airplane hangars. This is a two component product that requires 5 parts of the proper "A" component mixed with 1 part of part "B" catalyst. The components are already premeasured to the proper mix ratio. No measuring required. Do not mix partial kits.
Recommended for Properly Prepared and Primed Steel, Iron, Non-Ferrous, Concrete, and Fiberglass. Typical market segments include Food and Beverage Processing, Industrial Maintenance, Paper and Pulp Processing, Transportation, Industrial Flooring, General Metal Finishing / Fabrication, Chemical Processing, Commercial Structures, Tank Exteriors and other areas requiring a long life, performance urethane.
The performance of this product is directly dependent upon the degree of surface preparation employed. Prior to painting any surface, area must be clean, dry and free of all grease, dirt, dust, oil and wax. Clean using Corotech V600 Oil Grease Emulsifier. Remove all loose and peeling paint by wire brushing, scraping or sanding. Fill holes and cracks and sand smooth. Dull glossy surfaces by sanding. Moderate to heavily rusted areas must be thoroughly cleaned and primed.
Ferrous Metal: New metal surfaces should be primed with Epoxy Primer or Acrylic Metal Primer before applying V520. Apply one or two coats as needed.
Galvanized or Aluminum: Clean oil from new galvanized metal using Corotech® V600 Oil Grease Emulsifier or Lacquer Thinner using clean rags. Prime new or un-rusted metal with Epoxy Primer, Epoxy Mastic, Acrylic Metal Primer, or Waterborne Bonding Primer.
Plaster and Drywall: Sand surfaces and prime with a high quality acrylic primer.
Concrete Surfaces: Allow new concrete to age for a minimum of 30 days. Acid etch or abrasive blast smooth or glazed concrete floors. For acid etching use Concrete Etch. Be sure to follow the instructions when mixing and using solution. (Protect skin and eyes by wearing rubber gloves and goggles.) Rinse surface thoroughly with clean water and allow to dry. On floor applications, apply 1 coat Epoxy Pre-Primer. Old painted concrete should be sanded. Prime with Primer Sealer Stain Blocker, if previous finish is peeling, remove completely. Apply one or two coats of V520 as needed.
Fiberglass: Can be applied directly to clean, previously unpainted fiberglass. Scuff sand fiberglass to promote better adhesion.
WARNING! If you scrape, sand, or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National Lead Informational Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead .
Mix the “A” and “B” components thoroughly before mixing together. The use of a drill mixer at low speed will best accomplish this task. Add the full contents of the quart size “B” component to the “A” and thoroughly mix the two together. No induction time required prior to applying the mixed product to the substrate. Do not apply Corotech® Polyester Urethane if air or surface temperatures are below 50 °F or above 100 °F, or in relative humidity levels greater than 85%, or if surface or air temperatures are within 5 degrees of the dew point. Product should be allowed to dry tack free prior to air or surface temperatures being within 5 degrees of the dew point. This product is formulated to be applied without thinning. Airless Spray (Preferred Method): Tip range between .013 and .017. Total fluid output pressure at tip should not be less than 2400 psi. Air Spray (Pressure Pot): DeVilbis MBC or JGA gun, with 704 or 765 air cap and Fluid Tip E. Where non-skid characteristics are desired, hand broadcast an appropriate anti-slip aggregate into the wet film then back-roll to encapsulate. Benjamin Moore’s Corotech® Anti-Slip Aggregate V630 works well for non-clear coats.
