M974
Technical Data Sheet
Epoxy Tooling Board
Intermediate-temperature Use, Low CTE

CURE PARAMETERS FOR USE WITH SikaBlock

M974 Tools:

To protect from excess movement, cracking, thermal shock, or warpage the temperature differential ( T) between
the center of the tool and the external surface should never exceed 55 F on either ramp up or cool down. To
achieve this, temperature soaks of 6-8 hours every 55 F up and down in the oven and temperature ramp rates of
no more than .5 F/min are recommended, Leave the tool in the oven for at least 6-8 hours below 100 F before
opening doors and exposing the tool to room temperature conditions. Do not cure or use over a 235 F temperature.

ASSEMBLY

The recommended adhesive for bonding SikaBlock

M974 is EL-336 laminating resin. Cure adhesive 16 24 hours at
room temperature before applying the heat cure to adhesive (this is all before machining board to shape needed). Heat
cure the adhesive per slow ramp rate/soak rates given above to the required tool or part cure temperature needed up
to 235 F maximum. Machine board to final shape only after curing adhesive per these parameters.

These machining parameters represent starting points. Cutter type and material, spindle speed, feed
rate, machine power and rigidity all affect machining results. User must determine the best parameters for
specific situations.

STORAGE CONDITIONS

Product should be stored in a flat and dry place between temperature ranges no greater than +15 C and
+40 C (+60 F and 104 F).

PROCESSING CONDITIONS
Cutting suggestions for tooling planks
cutting horizontally on a planer mill: Head is
a 10 insert, 8 in diameter. For best results
use 5 inserts. Inserts are SFE-42E-10J-C5. We
have found a C2 Carbide insert does not chip
as easily. RPM 2200-2400 table feed 50-55
inches per minute. Some modifications may
be needed.
Saw Blades: A carbide- tipped, positive rake
saw blade with air slots should be used, if
possible. We suggest alternate top bevel ATB
or triple chip grind TCG rpm, depending on the
saw. We suggest 3,500 max rpm. Check with
manufacturer on saw and blade size. 12
blade, 48 teeth 16 blade, 48 teeth 18 blade,
60 teeth.
When sawing, you may need to back
part away from blade to relieve heat and
binding, then proceed with cut. It may be
necessary to take more than one cut to
achieve best finish.
Assembly/Finish: SikaBlock PP152 can be
bonded with the TCC-230 epoxy adhesive.
TCC-5220 is recommended to be used for the
patch paste.

Normal health and safety precautions should be
observed when handling these products:

CUTTING SUGGESTIONS FOR TOOLING PLANKS

CUTTING HORIZONTALLY ON A PLANER MILL: Head is a 10 insert, 8 in diameter.For best results use 5
inserts.Inserts are SFE-42E-10J-C5.We have found a C2 Carbide insert does not chip as easily.RPM 2200-2400
table feed 50-55 inches per minute.Some modifications may be needed.

SAW BLADES: A carbide-tipped, positive rake saw blade with air slots should be used, if possible.We suggest
alternate top bevel ATB or triple chip grind TCG rpm, depending on the saw.We suggest 3,500 max rpm.Check
with manufacturer on saw and blade size.
12 blade, 48 teeth
16 blade, 48 teeth
18 blade, 60 teeth
When sawing, you may need to back part away from blade to relieve heat and binding, then proceed with cut.It
may be necessary to take more than one cut to achieve best finish.
