N-Methylimidazole (NMI)
Addocat 102 is a blowing catalyst, improves adhesion to facings in rigid foam panels.
Function of Addocat 102:
Addocat 102 is a catalyst for the production of rigid polyurethane foam.
Addocat 102 is a polyurethane catalyst based on a tertiary amine, specifically N-methylimidazole.
Addocat 102 activates the gelling (cross linking) reaction in rigid polyurethane foams.
Addocat 102 produces tough and elastic skin, thus improving the adhesion of the foam to facings.
Typically Addocat 102 is used in the continuous production of sandwich panels, discontinuous hear/cold insulation if refrigerators and piping, and for on-site casting.

Product information about Addocat 102:
In rigid foams Addocat 102 catalyses mainly the crosslinking reaction (isocyanate-polyol).
For the production of these materials Addocat 102 is used as a co-catalyst in combination with Addocat 726 b, Addocat 104 or Addocat PP.
Addocat 102 gives the rigid foam a tough and elastic skin, thus improving the adhesion of the foam to facings, particularly in sandwich panels.
Dosage:
0.5 - 1.0 p.b.w. Addocat 102, calculated on 100 p.b.w. polyol, together with 1 - 3 p.b.w Addocat PP or Addocat 726 b or 0.3 - 1.0 p.b.w. Addocat 104.
Applications of Addocat 102:
- Continuous production of sandwich panels.
- Discontinuous heat/cold insulation of refrigerators and piping.
- On-site casting.
Packing of Addocat 102:
Metal drums, contents 190 kg
Storage stability of Addocat 102:
When Addocat 102 is stored in firmly closed original containers at 20 °C, a shelf life of 6 months can be expected.
Handling of Addocat 102:
Consult material safety data sheet (MSDS) for additional handling information for Addocat 102.
