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 #646 Heat
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

CURE CYCLE
Immersion/Full Chemical and/or heat Exposure 5 days
Force cures must be used for enhancement of high temperature and chemical
resistant properties or to allow the coating to be placed in service before
5 days. Allow the coating a post cure of 12 to 24 hours before force curing.
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 1 day 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.
