Epoxy.com Product #633 Novolac Epoxy - Highly Chemical Resistant Epoxy Coating is a 100% solids epoxy Novolac coating ideal for harsh chemical and solvent resistant applications. Epoxy.com Product #633 Novolac Epoxy - Highly Chemical Resistant Epoxy Coating is used in secondary containment, solvent storage, pump pads, trenches, and other high exposure areas.
Epoxy.com Product #633 Novolac Epoxy - Highly Chemical Resistant Epoxy Coating is ideal for use as a protective coating for concrete and steel in the extremely corrosive areas of chemical plants and pulp mills secondary containment areas, water and waste treatment, and gas and electric utilities. Epoxy.com Product #633 Novolac Epoxy - Highly Chemical Resistant Epoxy Coating is commonly used as a seal coat for Epoxy.com MORTAR SYSTEMS where chemical resistant performance is required.
SURFACE PREPARATION
Surface Preparation is the most critical portion to any successful resinous system application. All substrates must be properly prepared as outlined in Epoxy.com Surface Preparation Procedures.
Concrete
Surface must he clean and sound. Remove all dirt, laitance, grease curing compounds and other foreign matter by sandblasting, mechanical abrasion, or acid etching. Remove water and dust from all surfaces with an oil-free blast immediately prior to application.
Steel
Immersion Service
Sandblast to near white metal - (SSPC10 / NACE2).
Non-Immersion Service
Sandblast to Commercial Blast (SSPC10 / NACE3)
For more information on surface preparation please see the Epoxy.com Surface Preparation Guide.
INSTALLATION
Installation methods for Epoxy.com Product #633 Novolac Epoxy - Highly Chemical Resistant Epoxy Coating will vary with application method. See Coating Installation Guide for use in typical coating applications.
Mixing
Stir both component with separately before mixing together. Be sure not to cross contaminate the "A" into the "B" or visa versa. Mix for 3 minutes using an Epoxy.com (drill) mixing paddle or equal on a low speed drill.
If Epoxy.com Anti-Skid Course or Epoxy.com Anti-Skid Fine is to be used add 12-16 volume ounces per mixed gallon, and mix until properly dispersed, typically 1-2 minutes.
When Used as a Coating
When Epoxy.com Product #633 Novolac Chemical Resistant Coating is applied over concrete or wood, prime with Epoxy.com Product #899 and allow the Epoxy.com Product #899 to cure to tack free.
Application of Epoxy.com Product #633 Novolac Chemical Resistant Novolac Coating can be done by brush, roller, squeegee, or airless spray. Airless spray is best done with higher end binary airless spray equipment.
For typical installations as a coating apply 2 coats of Epoxy.com Product #633 Novolac Chemical Resistant Coating at a rate of 160-200 square feet per gallon per coat. This yields a wet film thickness of 8-10 mils thick per coat or 16 - 20 mils for the two coats. Since this is a 100% solids Epoxy Resin and Epoxy Hardener system, there is no loss during drying, so the wet film thickness and the dry film thickness for 2 coats will be identical (16-20 mils DFT).
If Epoxy.com Anti-Skid Fine or Anti-Skid Course is used add plus or minus 12 volume ounces of Anti-Skid per mixed gallon of Epoxy.com Product #633 Novolac Chemical Resistant Coating. Never add more than 16 volume ounces per gallon of Epoxy Resin and Epoxy Hardener mix.
