Chemical Resistant Epoxy Novolac Coating

Highly Chemically Resistant Novolac Epoxy Floor Coating  and Novolac Epoxy Wall Coating

100% Solids - Zero VOC Chemical Resistant Epoxy Coating & Flooring

Chemical Resistant Novolac Epoxy Flooring & Coating System, Product #633

---

Product #633 Novolac Epoxy is a highly chemical-resistant, 100% solids, zero-VOC novolac epoxy coating engineered for floors, walls, secondary containment, and harsh industrial environments. It provides superior protection in chemical plants, pulp and paper mills, water and wastewater treatment facilities, solvent storage areas, pump pads, trenches, and other high-exposure locations. Product #633 is also used as a seal coat for epoxy mortar systems and as a chemical resistant epoxy flooring and wall coating where maximum chemical resistance is required.

NOVOLAC EPOXY #633 ADVANTAGES

• Exhibits excellent resistance to strong acids, alkalis, and most industrial chemicals and solvents
• Can be applied in cool damp conditions
• Can be re-coated in 4 to 6 hours
• Can be applied in occupied facilities
• Forms a virtual moisture barrier
• Meets USDA standards
• 100% solids - 0.0 lbs VOC - meets even the most strict low VOC requirements

CONSIDERATIONS

• Concrete substrate  to receive Product #633 Novolac Epoxy must be free of dirt, waxes, curing agents, and other foreign materials.
• Steel surfaces  to receive Product #633 Novolac Epoxy must be free of grease and oils. Abrasive blast to SSPC-SP5.
  

COMPOSITION

• 100% solids, modified amine adduct cured epoxy Novolac resin.
  

APPLICATION

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 Surface Preparation Procedures.

Concrete to Receive Chemical Resistant Novolac Epoxy Coating #633

Surface must be 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 to Receive Chemical Resistant Novolac Epoxy Coating #633

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 of Chemically Resistant Novolac Epoxy Coating #633

Installation methods for Product #633 will vary with application method. See Coating Installation Guide for use in typical coating applications.

Mixing

Stir both components 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 Anti-Skid Course or 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 Product #633  is applied over concrete or wood,  prime with Product #12 Chemical Resistant Epoxy Primer and allow the Product #12 Primer to cure to tack free. Priming is optional over gray metal blast steel.

Application of Product #633 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 Product #633 Novolac Epoxy  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 Resin and 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 Anti-Skid Fine or Anti-Skid Course epoxy anti-skid additive is used add plus or minus 12 volume ounces of Anti-Skid per mixed gallon of Product #633. Never add more than 16 volume ounces per gallon of Resin and Hardener mix.
