Description
DABCO® TMR 2 is a tertiary amine that promotes the polyisocyanurate
reaction (trimerization). It provides a uniform and controlled rise
profile
compared to potassium based catalysts. DABCO® TMR 2 is used in
rigid foam applications where improved flowability compared to
DABCO® TMR
catalyst is required. It can also be used in flexible moulded foam
applications for back end cure.
Physical properties
Special properties/Highlights
Strong trimerization catalyst
Improved curing
High isocyanate conversion
Tailors system reactivities
Provides more delayed action than DABCO® TMR catalyst
Application
DABCO® TMR 2 is suitable for all types of polyisocyanurate foam
systems. It is typically used in combination with a
polyurethane-type catalyst, such as POLYCAT® 8 or DABCO® R 8020. A
typical starting point employs 2.0 php of DABCO® TMR 2 and 0.8 php
of POLYCAT® 8. DABCO® TMR 2 can also be used in combination
with other members of the DABCO® TMR catalyst family (DABCO® TMR,
DABCO® TMR 3 and DABCO® TMR 4) to tailor system reactivities to
meet specific needs.
DABCO® TMR 2 is somewhat delayed compared with DABCO® TMR, and
initially more reactive than DABCO® TMR 3. DABCO® TMR 4, in
particular, was specifically designed to enhance the flowability of
isocyanurate systems.

Recommended storage conditions
DABCO® TMR 2 has a shelf life of 24 months from the date of
manufacture and under the condition, that it is stored in
factory-packed containers and protected against
extreme weather conditions, particularly against heat and moisture.
extreme weather conditions, particularly against heat and moisture.
The optimum storage temperature of DABCO® TMR 2 is in between 10 °C
and 30 °C. Lower and higher storage temperatures are not preferable
and should be avoided.
