421-82XX E-Var 550 Post-Cat Clear TC

E-Var 550 is recommended for office and household furniture, kitchen cabinets, as well as many other high performance interior wood applications. E-Var 550 is designed for use on all types of solid wood and veneer meant for interior use.

Substrate must be sanded using 120 or 150 grit stearated paper prior to staining or coating. When sealing, the sealer coat should be sanded prior to being coated with 240/280/320 grit stearated paper. The sealer should be topcoated within eight hours of being sanded. This product is designed to be used as a self seal. When recoating, the previous coat of E-Var 550 must be sanded and the next coat applied within eight hours. E-Var 550 cannot be used on metal, old oil or cellulose lacquers. Stain systems used under acid catalyzed systems should be acid stable. AkzoNobel recommends using 825-00XX or 825-09XX series stains or 824-50XX series waterborne stains.

Agitate material before use. E-Var 550 must be agitated thoroughly at all times to ensure product consistency and consistent gloss. Always mix E-Var 550 while adding hardener and reducers in the recommended mixing ratios. Apply at 3-5 mils wet on sanded substrate. Further coats may be applied after complete drying followed by sanding with 280/320 grit stearated paper. The second and subsequent coats must be applied the same day as the previous coat is sanded.

Maximum film build of E-Var 550 should not exceed 4 mils dry. Maximum film build of total coating system must not exceed 4 mils dry. Contact with metal surfaces should be avoided.

E-Var 550 must not be polluted with oil, varnish or the like and must not be sanded with steel wool between the coats. E-Var 550 must not be used and dried at temperatures below 64°F or relative humidity above 65%. During hardening the coating must not be exposed to ammonia vapors. Ammonia cleaners should not be used for cleaning the finished surface. This may accelerate discoloration.

Please note that, as with any other amino-containing product, this material contains, and has the potential to emit, formaldehyde (CAS# 50-00-0). As per the US Department of Labor Standard 29 CFR 1910.1048 covering formaldehyde, section (d)(1)(i) states that “Each employer who has a workplace covered by this standard shall monitor employees to determine their exposure to formaldehyde.” Please refer to the OSHA web site at www.osha.gov for further information.
