L-66L CLEAR BAKED PHENOLIC COATING
| GENERIC TYPE: Baking phenolic RECOMMENDED USAGE: Heresite L-66L baking phenolic coating offers consistent, high-quality service in a wide range of applications in immersion service for most acids, solvents, and salts. Typically Heresite L-66L is used over the Hersite P-403 or P-403L brown baking phenolic coatings to provide improved release properties and/or to prevent some products from contacting the pigment of the Heresite P-403 or P-403L brown coatings. Heresite L-66L is also used as an electrical insulator. Applications include: tank linings, fans, blowers, filter plates, tank car, tank trailers, duct work, exhaust hoods, and other industrial equipment. Heresite L-66L meets the requirements of the U.S. Federal Register, Food and Drug Regulations, Title 21, Chapter 1, Paragraph 175.300. This material is also available with plasticizers which improve flexibility.
PHYSICAL DATA:
ABRASION RESISTANCE: A 43 mg loss is observed with a Tabor Abrasor CS-17F wheel with a 1000 g. weight for 1000 cycles. TEMPERATURE LIMITATIONS: Heresite L-66L accepts dry heat temperatures up to 400°F (204°C) STANDARD COLOR: Amber COVERAGE: Theoretical coverage -- 896 square feet per gallon per mil. Recommended total dry film thickness is 1.5 to 2.0 mils in a 1-2 coat system. (At 1.5 mils DFT, average coverage would be 478 square feet per gallon. This includes a 20% loss factor.) SURFACE PREPARATION: Remove all oil or grease from the surface with an appropriate solvent. STEEL: NON-IMMERSION: A commercial blast is acceptable in accordance with NACE #3, or SSPC-SP-6-63 specifications. PRIMER: Normally L-66L is used as a top coat for Heresite P-403 or P-403L brown baking phenolic coatings. L-66L may be used without primer. THINNER: Under normal conditions we recommend use of Heresite S-217 Solvent. In hot weather or open rooms we suggest Heresite S-276. In confined spaces or cooler weather, use Heresite S-215. THINNING: The amount of thinner required is dependent upon temperature, ventilation, humidity, spray equipment used, and desired film thickness. Suggested thinning at 75°F (24°C) is 20-30%. MIXING: Mix thoroughly and adjust viscosity per manufacturer's recommendations. (Approximately 20 seconds with a Zahn #2 cup at 72°F or 15 seconds with a Ford #4 at 72°F.) APPLICATION:
CLEAN UP: Use Heresite S-215 Solvent. STORAGE CONDITIONS: Coating should not be stored longer than 4 mos. at 70°F (21°C). |
