DESCRIPTION
ES-221 is a hydrophobic epoxy system (cures in the presence of water) engineered primarily for use as a high temperature surface coat for
plastic faced plasters or high temperature molds requiring a high-gloss surface. Available in white resin for easy viewing of scribe lines on
PFP masters or black resin for RTM or contact molding applications requiring a high-gloss finish. The versatility of this room temperature
cure, 300 F (149 C) high temperature capable system (see post cure schedule), provides the engineer with a wide range of applications.
Popular handling properties producing accurate, detailed, chip resistant surface coat duplications in epoxy laminate or cast tool fabrication.
Typical applications include: Plastic Faced Plasters, Vacuum Molds, Checking Fixtures, Duplication Molds, Spotting Racks,
Bonding Fixtures and RTM Molds.

APPLICATION GUIDE
Proper Preparation Of Model Or Pattern Surface
Note: A porous surface needs to be completely sealed before a mold release is applied. Whichever sealer you choose to use you
should refer to sealer instructions regarding number of coat applications and dry-to-cure-times before applying mold release.
Note: A non-porous surface should be thoroughly cleaned before applying mold release. Refer to application instructions of mold
release.
Once your model or pattern are properly released, catalyze ES-221 surface coat and brush on a 0.030″ to 0.040″ coating, taking care not to
entrap air or puddle resin in corners or at the bottom of steep details.
When surface coat reaches “tack-stage (resin will not stick to your finger when touched but soft and sticky enough to leave fingerprint)
immediately brush on a second layer of catalyzed ES-221 surface coat to a thickness of .030″ to .040”, followed by the pouring of plaster
onto wet surface coat, filling cavity.
NOTE: Prior to pouring of plaster, some fabricators prefer to sprinkle or broadcast sisal fibers on to 2
nd
wet surface coat to secure a
mechanical bonding feature.
POST CURE SCHEDULE
16 24 hours @ 77 F (25 C)
+2 hours @ 150 F (66 C)
+2 hours @ 200 F (93 C)
+2 hours @ 250 F (121 C)
+2 hours @ 300 F (149 C)
NOTE: The post cure schedule pertaining to the high-temp epoxy laminate, casting system or plaster used with your tooling surface
coat would have precedence over that of the surface coat. However, to attain suitable temperature resistance and chemical resistance,
the surface coat is recommended to be post cured to a minimum temperature of 200 F (93 C).

HEATING AND COOLING RATES DURING POST CURE
Always allow tools made with high-temp resin systems to gel at room temperature before subjecting them to post cure (16 to 24 hours
is usually sufficient). When oven curing, place mold in a room temperature oven, increasing temperature at a rate of 50F per hour.
When cooling, allow molds to remain in heated oven, decreasing the temperature at a rate of 50 F (30 C) per hour. Do not remove
mold from oven until temperature has been lowered to 100 F (38 C).

DESCRIPTION
ES-218 is white, thixotropic, room temperature cure, sandable epoxy surface coat designed for duplication work. The popular handling
properties of ES-218 produce accurate, detailed, chip resistant surface coat duplications in epoxy laminate fabrications.
The versatility of this resin system, when used with ES-218-1 Hardener, also doubles as a chemical resistant epoxy coating used to fill
surface texture on composite parts. Typically one application applied using brush or roller is all that is required to fill in the texture or weave
in cloth fabric. NOTE: Do not topcoat directly over ES-218-1 composite coating applications. Sand ES-218-1 and use surface primer
products as recommended by topcoat manufacturer. Typical applications include: masters, models, patterns, duplicating, engineering
tooling, checking and drill fixtures and as a composite coating.

DESCRIPTION
EL-337 is an improved, health-safe, two component, filled, non-staining, high temp epoxy laminating system specifically
developed for room temp hardening (B Stage) with high temp properties for high temp tooling applications. EL-337 has
excellent handling properties and fabric wet-out to produce a void free tool with high dimensional stability. EL-337 can be
used in the construction of large or small tools, as well as production parts. EL-337 can also be used with ADTECH High
Temp Surface Coats ES-219 and ES-229. Tools made with EL-337 can be used at continuous temperature of 320 F
(160 C), and intermittent temperatures up to 375 F (191 C). While EL-337 will gel at room temp, it must be post-cured to
achieve ultimate strength. The system contains no MDA or VCHD. Typical applications include: vacuum form molds,
prototype injection molds, high temperature bonding fixtures, spray metal molds, compression molds, high
temperature laminated molds and parts to be used in high temp applications.

PRELIMINARY CURE SCHEDULE
On model: Cure for 24 hours @ 77 F (25 C)
+ 2 hours @ 150 F (66 C)
You may attach support structure and demold tool after this schedule is completed.
POST CURE SCHEDULE
After completing the Preliminary Cure Schedule, complete the following:
2 hours @ 200 F (93 C)
2 hours @ 250 F (121 C)
3 hours @ 300 F (149 C)
HEATING AND COOLING RATES DURING POST CURE
Always allow tools made with ADTECH high temp systems to gel at room temperature before subjecting them to post cure
(24 hours is usually sufficient). This will prevent excessive exotherm and shrinkage from occurring.
When oven curing laminated molds, always place the mold in a room temperature oven. Increase oven temperature at a rate
of no more than 50 F (30 C) per hour. When heat cure is completed, turn off oven and allow molds to remain in the oven.
Never remove mold from oven until mold temperature has been lowered to less than100 F (38 C).
