Bis(2-dimethylaminoethyl)ether (BDMAEE) in DPG
Addocat 108 is a standard strong blowing catalyst for rigid and flexible foams, improves flowability.
Addocat 108 is a polyurethane catalyst based on a tertiary amine, specifically Bis-(2-diemthylaminoethyl)-ether cut in DPG.
Addocat 108 strongly activates the blowing reaction for flexible and rigid polyurethane foams.
In rigid foams, improves the flow of the reaction mixture, normally used as a co-catalyst.
Function of Addocat 108:
Addocat 108 is used for the production of polyurethane flexible slabstock foam and hot-moulded foam.
Addocat 108 is also used for HR foam and, as a co-catalyst, for rigid foams.
Addocat 108 is a mixture of bis-(2-dimethyl-aminoethyl)-ether and dipropylene glycol.
Addocat 108 acts as a activator for the production of polyurethane flexible slab-stock foam and hot-molded foam.
Addocat 108 is also used for HR foam and, as a co-catalyst, for rigid foams.
Addocat 108 has a shelf life of 12 months.

Product information about Addocat 108:
Addocat 108 is a powerful catalyst for the gas reaction.
Flexible polyether foam:
Addocat 108 is one of the standard catalysts used to promote the gas reaction in the production of polyether slabstock foam and hot-moulded foam (dosage 0.1 - 0.15 p.b.w. on 100 p.b.w. polyol).
Here it is always used in combination with Addocat SO (0.1 - 0.3 p.b.w.).
HR foam (moulded and slabstock foam):
In this case the reaction can be controlled with Addocat 108 (0.1 - 0.5 p.b.w. on 100 p.b.w. polyol) in combination with Addocat 105 (0.3 -1.0 p.b.w.).
Filling foam:
In the production of semi-rigid filling foam it has been found advisable to use triethanol amine (up to 4.0 p.b.w.) in addition to Addocat 108.
This gives a more open cell structure.
Rigid foam:
In rigid foam systems Addocat 108 is used only as a co-catalyst in combination with Addocat 726 b, Addocat 1926, Addocat 1221 or Addocat 9412.
Even small additions of Addocat 108 (0.1 p.b.w.) improve the flowability of the system.
Applications of Addocat 108:
- Continuous production of panels and slabstock.
- Discontinuous heat/cold insulation of piping and refrigerators.
Packing of Addocat 108:
Metal cans, contents 50 kg
Metal drums, contents 175 kg
Plastic-IBC, contents 800 kg
Storage stability of Addocat 108:
When Addocat 108 is stored in firmly closed original containers a shelf life of 12 months can be expected.
Possible yellowing of the liquid in the course of time has no influence on the product's catalytic effect.
Handling of Addocat 108:
Consult material safety data sheet (MSDS) for additional handling information for Addocat 108 .
