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.

n: Spindle speed in revolution/min Vf: feed speed in inches (mm)/min
(1) Rough cut: Cutting parameters are determined with a carbide-insert ball nose end mill:
Helix angle: 6
Clearance angle: 14
(2) Finishing cut: Cutting parameters are determined with a 2 teeth ball nose end mill:
Helix angle: 30
Clearance angle: 14
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:
Ensure adequate ventilation
Wear gloves, glasses, and protective clothes
For further information, please consult the Safety
Data Sheets.
STORAGE CONDITIONS
Store flat in a dry place. Allow time for
material to come to ambient temperature
prior to bonding or machining.

PRODUCT DATA SHEET
SikaBlock PP152 (Formerly PP-1052)
Polyurethane Tooling Board
TYPICAL PRODUCT DATA (FOR FURTHER VALUES SEE SAFETY DATA SHEET)
DESCRIPTION
SikaBlock PP152 is a filled,
polyurethane- based tooling board for
foundry pattern making, molds, tools,
and other applications.
PRODUCT BENEFITS
– Very good abrasion resistance
– Good toughness and impact resistance
– Easy to seal and varnish
– Low dust formation when milled
– High dimensional stability
– Easy machinability
– Good compression strength and edge
stability
– Can be polished to a high gloss
AREAS OF APPLICATION
SikaBlock PP152 is suitable for a wide range of
applications, ranging from prototype and low-
volume models and tools, to high- volume
foundry patterns, core boxes, match plates,
gating and risering. Other potential
applications include metal forming, vacuum
forming, headliner tools, hammer forming,
stretch press dies, hemmingbucks and
production checking, holding, and assembly
fixtures.
Tests with actual materials and conditions
have to be performed to ensure satisfactory
performance.

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:
Ensure adequate ventilation

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:

PRODUCT DATA SHEET
SikaBlock PP152 (Formerly PP-1052)
Polyurethane Tooling Board
TYPICAL PRODUCT DATA (FOR FURTHER VALUES SEE SAFETY DATA SHEET)
DESCRIPTION
SikaBlock PP152 is a filled,
polyurethane- based tooling board for
foundry pattern making, molds, tools,
and other applications.
PRODUCT BENEFITS
– Very good abrasion resistance
– Good toughness and impact resistance
– Easy to seal and varnish
– Low dust formation when milled
– High dimensional stability
– Easy machinability
– Good compression strength and edge
stability
– Can be polished to a high gloss
AREAS OF APPLICATION
SikaBlock PP152 is suitable for a wide range of
applications, ranging from prototype and low-
volume models and tools, to high- volume
foundry patterns, core boxes, match plates,
gating and risering. Other potential
applications include metal forming, vacuum
forming, headliner tools, hammer forming,
stretch press dies, hemmingbucks and
production checking, holding, and assembly
fixtures.
Tests with actual materials and conditions
have to be performed to ensure satisfactory
performance.
