High Temperature Resistant Epoxy Mortar


DESCRIPTION

Epoxy.com PRODUCT #646 Heat Resistant Epoxy is a two component translucent black highly cross-linked novolac epoxy resin system. Epoxy.com PRODUCT #646 is especially formulated to be used as a high temperature grouting or laminating resin. It is used to protect concrete, steel and other substrates from high temperatures and corrosion. Epoxy.com PRODUCT #646Heat Resistant Epoxy is similar to Epoxy.com Product #641, Heat Resistant Epoxy but does not have the pigments that Epoxy.com Product #641 has.

ADVANTAGES

  • Stable up to 400°F
  • High chemical resistance to acids, alkalies and other chemicals
  • Low viscosity allows penetration into fiberglass fabric to make high temperature composites
  • Low viscosity allows filler loading for high temp epoxy grout

USES

  • Steel and Concrete Protective Surface where high temperatures are encountered:
  • Chemical processing plants and equipment
  • Food and dairy processing plants
  • Utility plants
  • Industrial Plant Flooring under thermal units
  • PGD scrubber duct
  • Tanks and vessels
  • De-min concrete pads
  • Water boxes
  • Ball mill sumps
  • Heat Exchangers

RECOMMENDED FORCE CURE SCHEDULE
Minimum 4 hours @ 150°F
Minimum 6 hours @ 250°F

CURED: Chemical resistance

acids, alkalies, alcohols, ketones, aromatics and other solvents.

SURFACE PREPARATION

Concrete: Remove dirt, loose particles and oil contaminants by scarification, sandblasting, Shotblasting. Vacuum surface before application.

Steel: Remove all grease, dirt and other contaminants from surface prior to sandblasting. Grind sharp edges to a radius of 1/8". Remove all weld splatters. Sandblast to a white metal finish according to SSPC-SP-5-63 or NACE standard TM-01-70 with a minimum anchor profile of 3 mils.

MIXING

Mix 2 parts "A" Component with 1 part "B" Component using a slow-speed drill and Epoxy.com - Mixing Paddle for 3-5 minutes. Apply immediately. High temperatures will shorten pot life.

APPLICATION

Epoxy.com PRODUCT #646 Heat Resistant Epoxy can be applied by brush, roller or trowel. Epoxy.com PRODUCT #646 can be applied by trowel or grout pump. Epoxy.com PRODUCT #646 Heat Resistant Epoxy is designed as a one coat system (minimum 45 mils, maximum 300 mils). Substrate temperature should be a minimum of 60°F for application to commence. If a second coat is needed before the first coat cures, no surface preparation is needed. Simply apply the second coat maintaining the required standards. However, if the first coat has cured longer than 7 days the first coat must be brush blasted prior to the second coat.

COATING: One gallon covers approximately 26.7 ft.2 at 60 mils

Grout: Epoxy.com PRODUCT #646 can be easily made into a heat resistant epoxy grout by adding from 1 to 3 parts by volume of Product #76 Epoxy Extender to the mixed epoxy.

3 gallons Epoxy.com PRODUCT #646 + (3) 48 lb. bags #76 = 2,246 cu.in. per unit

CLEANING: Clean all equipment immediately after use with MEK or acetone.

CAUTION

"A" Component contains epoxy resin. DANGER! "B" Component contains alkaline amines; strong sensitizer. May cause skin sensitization or other allergic responses. Use with good ventilation, particularly if material is heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves and/or barrier creams.
