* Denotes physical testing conducted on 6 ply 7500 Style E-Glass Laminate
PROCESSING
A prelimInary self-support cure schedule can
be used on a model, mold, or plug. Cure for 24
hours at 77 F (25 C) + 6 hours at 150 F (66 C).
You may attach support structure and de-
mold tool after this schedule is completed,
then apply post-cure. It is recommended to
install thermocouples to monitor the mold
temperature throughout the post cure
process, if possible.
POST-CURE HEATING AND COOLING RATES
Always allow tools made with Sika high
temperature epoxy systems to gel at room
temperature before subjecting them to post
cure (24 hours is usually sufficient). This will
prevent excessive exotherm and shrink stress
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 than 100 F (38 C). A lternative
post-cure options can be used, if needed, in
processing. Contact Sika Corporation s Industry
Technical Services Department at
tsmh@us.sika.com for additional information and
advice.
Normal health and safety precautions should be
observed when handling these products:
Ensure adequate ventilation
Wear gloves, glasses, and protective clothes

DESCRIPTION
EC-433 aluminum filled epoxy casting systems are developed for use in heat resistant tooling applications such as
prototype injection molding, vacuum forming, and other high temperature cast tooling applications. EC-433 offers 3
hardener options with various working times, suitable for any tool size. EC-433 is a room temperature hardening (B
Stage) system, but a post cure is necessary for use over 150 F (66 C). Tools made with EC-433 can be used at
continuous temperatures of 300 F (160 C) and intermittent temperatures up to 350 F (177 C). EC-433 features easy
mixing, accepts higher loading of bulk aluminum, and exhibits greater dimensional stability.

RECOMMENDED CURE SCHEDULE
PRELIMINARY CURE:
24 hours @ 77 F (25 C) + 3 hours @ 150 F (66 C) is the minimum cure temperature
You may de-mold tool after the preliminary schedule is complete and the tool has cooled.
POST CURE SCHEDULE:
A conditioning post cure at a temperature equivalent to the constant operational temperature of your production mold is
advised. If an additional post cure is necessary beyond the preliminary cure schedule, the recommended cure schedule is
as follows:
2 hours @ 200 F (93 C)
2 hours @ 250 F (121 C)
2 hours @ 300 F (149 C)
Ensure proper heat curing temperatures are met by installing a thermocouple directly in the center of the tool.
Notes: It is always advisable to heat cure cast epoxy molds internally by using the copper tubing temperature control
system built into your mold.
***If oven curing is your only option, it is advisable to complete the initial cure on the model at 125 F (52 C) for 8 hours
or overnight before reverting to the higher post cure temperatures outlined above.

***Extremely large cast molds should always be heat cured internally and not moved or transported prior to
completing an internal heat cure process of 150 F (66 C) minimum.
***Always allow a cast tool to cure 24hrs at room temperature before heat cure. This will prevent excessive exotherm and
shrink stress from occurring.
***When taking cast tools through a preliminary or post cure phase always place tool in a room temperature oven and
increase temperature at a rate of no more than 50 F (30 C) per hour.
***When cooling cast tools, always allow tool to remain in heat environment and decrease temperature at a rate of no
more than 50 F (30 C) per hour. Do not remove tool from heat environment until center of tool has reached 100 F (38 C)
or less. Removing tool at temperatures above 100 F (38 C) can result in thermal shock and warping.

HIGH TEMPERATURE EPOXY CASTING SYSTEM
ALUMINUM FILLED
DESCRIPTION
EC-433 aluminum filled epoxy casting systems are developed for use in heat resistant tooling applications such as
prototype injection molding, vacuum forming, and other high temperature cast tooling applications. EC-433 offers 3
hardener options with various working times, suitable for any tool size. EC-433 is a room temperature hardening (B
Stage) system, but a post cure is necessary for use over 150 F (66 C). Tools made with EC-433 can be used at
continuous temperatures of 300 F (160 C) and intermittent temperatures up to 350 F (177 C). EC-433 features easy
mixing, accepts higher loading of bulk aluminum, and exhibits greater dimensional stability.

INSTRUCTIONS FOR USE
1. Bonding surfaces must be clean, free of dust and fit tightly together. Sand any smooth or shiny surfaces to create a rough
texture for the adhesive to lock into. Clean oil contaminated metal surfaces with MEK solvent or lacquer thinner, thoroughly dry and
sand. Please note that EA-001 will not expand into gaps or fill loose joints so bonding surfaces should mate well together.
2. Lightly dampen surfaces to be bonded using a water dampened cloth or water spray mist bottle. EA-001 adhesive requires
moisture to cure however do not saturate surfaces. The optimum substrate moisture content is between 10-25%.
3. Spread a thin layer of EA-001 to both surfaces using a disposble brush or plastic spreader. Use a minimum of oz. per
square foot on each bonding surface (example: a 4 oz. bottle covers 4 square feet of surface A plus 4 square feet of surface B ).
4. Clamp the pieces together or use heavy objects to create pressure. Leave the clamps in place for at least 4 hours until the EA-
001 reaches a cure to handling strength.

DESCRIPTION
P-34 SET-FAST MODEL PLANK FILLER offers the pattern and model maker the capability of forming, shaping and working the cured filler
to precise and accurate trade applications without dulling or damaging tools. P-34 is ideal for finishing and changing fixtures made from
the new epoxy types of Model Planks (ref: TCC-1055 Model Plank). P-34 MODEL PLANK FILLER bonds to all types of wood and can be
finished to a feather edge by sanding, carving, machining or scraping. P-34 is a creamy, non-sag paste which mixes easily and saves time
and labor over other fillers which require longer cure. Typical applications include as a filler/patch for: master models, engineering
changes, fillets and radius areas and pattern/ fixture and tooling applications.

PRODUCT DATA SHEET
SikaBiresin AP007 (Formerly APF 7)
Styrene- Free Polyester Filler with High Temperature Resistance
TYPICAL PHYSICAL PROPERTIES (FOR FURTHER VALUES SEE SAFETY DATA SHEET)
DESCRIPTION
SikaBiresin
AP007 is a styrene-free,
very fast setting, polyester-based,
industrial filler paste. It is specifically
formulated for filling, fairiring, and
repair applications and can be used in
high service temperatures applications
up to 400 F (204 C). When exposed to
elevated temperatures, SikaBiresin
AP007 has a tendency to darken,
however it does not gas, bubble, or
cause any finish distortion. SikaBiresin
AP007 bonds readily to itself or other
substrates, such as FRP/SMC, high
temperature epoxy molds, aluminum,
steel, cast iron, and urethane foam
parts. In its mixed, uncured state,
SikaBiresin AP007 has a smooth,
creamy consistency that enables the
user to make quick repairs with minimal
air entrapment.
PRODUCT BENEFITS
– Excellent adhesion
– Very fast setting
– Easy to use
– Minimal shrinkage
– High chemical and water resistance
– Excellent finishing / machinability
– High service temperature
– Low moisture absorption
– Above and below waterline applications
– High gloss finish
AREAS OF APPLICATION
SikaBiresin
AP007 is specifically
formulated for use in the aircraft,
aerospace, marine and other industries
that perform manufacturing and repair
work on items requiring room
temperature or above normal
temperature ranges. It may be used in
underwater applications.
Tests with actual materials and conditions
have to be performed to ensure satisfactory
performance.
