ADDOCAT 1221 VN

Blend of tertiary amines in a polyether polyol 

Addocat 1221 VN is a balanced catalyst for rigid foam, applicable to PIR formulations.

Addocat 1221 VN is a blend of tertiary amines with polyetherpolyol. 
Addocat 1221 VN acts as a catalyst for the manufacture of rigid polyurethane foams and building boards.
 
Addocat 1221 VN is hygroscopic and should therefore be protected from humidity. 
Addocat 1221 VN should be stored in closed containers at temperatures of about 20°C. 

Addocat 1221 VN turns yellow to brown on exposure to air and light, but without losing its catalytic effect. 
Addocat 1221 VN allows a good start time and good cure. 

For PUR rigid foam the dosage is approx. 2.0 - 4.0 p.b.w. 
Addocat 1221 VN has a shelf life of 6 months.

Applications of Addocat 1221 VN:
Addocat 1221 VN is mainly used for the continuous production of PUR rigid slabstock foams and building boards. 
Addocat 1221 VN allows a better dosage, a good start time and good cure.

PIR rigid foam:
Typical dosage is 0.4 - 0.6 pphp of Addocat 1221 VN combined with special PIR catalyst.

PUR rigid foam:
Typical dosage is 2.0 - 4.0 pphp. 
In sandwich elements (d < 80 mm) with metal facings approx. 2.0 pphp are used.

Packaging of Addocat 1221 VN:
Plastic container, contents 900 kg.

Storage conditions of Addocat 1221 VN:
Addocat 1221 VN is to be stored in a dry place. 
When Addocat 1221 VN is stored in firmly closed original containers at dry conditions (hygroskopic) at approx. 20 °C, a shelf-life of 12 months from manufacturing date can be expected.
Addocat 1221 VN turns yellow to brown on exposure to air and light, but without losing its catalytic effect. 

The contents have to be thoroughly homogenized before use. 
The Addocat 1221 VN containers should be resealed tightly after use to prevent contamination by impurities and exposure to moisture.

Handling of Addocat 1221 VN:
Consult the safety data sheet for relevant safety data & references as well as possibly necessary warning labels.
