TECHNICAL DATASHEET
Technical Information:
Calculation for the Amount of Curative
The Prinzthane are isocyanate terminate prepolymers that
are designed to produce high-performance polyurethane
elastomers. These elastomers exhibit superior abrasion
resistance, high tear strength, excellent load bearing
ability and good toughness. The types of Prinzthane
available are booth TDI and MDI with polyester,
polyether, and polycaprolactone.
To calculate the desired amount of any curative for any
Prinzthane Prepolymer, the following formula may be
used:
Those types are:
2- Polyether PTMEG
T = TDI
3- Polyester
M= MDI
4- Poly Capralactone
Q = Quasi
For example: 3MQ = Polyester MDI Quasi

Melt Procedure For Prinzthane Prepolymers
Prinzthane Prepolymers are booth liquids and solids
depending on the type. Solid prepolymers and those liquid
that were exposed to cold temperatures and frozen can be
safely melted by using warming devices such as ovens,
warming blankets, and drum heaters. Caution should be
taken so as not to cause localized overheating. The time it
takes to melt a solid Prizethane Prepolymer is as follows:
Equivalent weights of some typical curatives
1.4 Butanediol
45
Ethacure 300
107
HQEE
99
Lonzacure M-CDEA
188.6
With a warming temperature of 60°C (140 °F):
MBOCA
133.5
1 gallon can
1-2 hours
TMP
44.7
5 gallon can
7-9 hours
55 gallon drum
35-40 hours
To ensure homogenelty after melting, the containers
should be rolled.
Original unopened containers do no need to be vented
prior to melting. If vented however a drying tube with a
moisture indicator should be used to prevent moisture
contamination. Moisture contamination can cause a loss of
NCO reactivity, stability, and mechenical properties of the
final elastomer.
Toxicity
Prinzthane are isoyanate terminated prepolymres
and as such should be handled with care. Avoid
breathing of vapors and skin contact. Use proper
ventilation and PPE. MSDS's are available for each
product and should be consulted before using Prinz
