Benzyldimethylamine (BDMA)
Addocat DB is a moderate activity universal gelling co-catalyst, good emulsifier.
Addocat DB is tertiary amine.
Addocat DB acts as a catalyst for the production of polyurethane foams, e.g. ester-based flexible slabstock foam and rigid foam.
Addocat DB slightly activates the crosslinking reaction.
Addocat DB is often used as a co-catalyst and gives rigid foam a tough and slightly elastic surface, especially in polyester-polyol containing systems.
Addocat DB is used mainly in the continuous production of slab-stock foam with densities higher than 50 kg/m3, on-site casting and continuous production of building boards with flexible and rigid or metal facings.
Addocat DB has a shelf life of 12 months.
Addocat DB is a polyurethane catalyst based on a tertiary amine, specifically N,N benzyldimethylamine.
Addocat DB activates the gelling reaction (cross linking) and is suitable for the production of polyester-based flexible slabstock foam and rigid polyurethane foam.
Addocat DB is also a good emulsifier for organic compounds.
Functions of Addocat DB:
Catalyst for the production of polyurethane foams, e.g. ester-based flexible slabstock foam and rigid foam.

Product information about Addocat DB:
Flexible slabstock foam (ester-based):
Addocat DB is an activator for the production of flexible polyester foam based mainly on TDI 65/35.
1.0 - 1.6 parts by weight Addocat DB, calculated on 100 parts by weight polyester polyol, are used, depending on the water content of the formulation (2.0 - 5.0 parts by weight water).
Since Addocat DB is insoluble in water, it can be emulsified in a mixture of water, Dispergiermittel WM and Zusatzmittel SM.
Rigid polyurethane foam:
Addocat DB slightly activates the crosslinking reaction.
Addocat DB is often used as a co-catalyst and gives rigid foam a tough and slightly elasticsurface, especially in polyester-polyol containing systems.
Applications of Addocat DB:
- Addocat DB is used mainly in the continuous production of slabstock foam with densities higher than 50 kg/m³.
Depending on the desired density, Zusatzmittel SM can be used simultaneously (at dosages of 1.0 - 4.0 parts by weight Zusatzmittel SM);
- On-site casting;
- Continuous production of building boards with flexible and rigid or metal facings.
PRODUCT DETAILS ABOUT ADDOCAT DB:
Addocat DB is a catalyst for the production of PUR foam, e. g. flexible ester slabstock foam and rigid foam.
FLEXIBLE ESTER SLABSTOCK FOAM:
Addocat DB is a catalyst for the production of flexible ester foam based mainly on TDI 65/35. 1.0 - 1.6 parts by weight Addocat DB per 100 parts by weight polyester polyol are used, depending on the water content of the formulation (2.0 - 5.0 parts by weight water).
Since Addocat DB is insoluble in water, it can be emulsified in a mixture of water, Addovate WM and Addovate SM.
RIGID FOAM:
Addocat DB is a weak catalyst for the crosslinking reaction.
Addocat DB is often used as a co-catalyst and gives rigid foam a tough and slightly elastic surface, especially in polyester polyol containing systems.
TYPICAL APPLICATIONS OF ADDOCAT DB:
Addocat DB is used mainly in the continuous production of slabstock foam with densities higher than 50 kg/m³.
Depending on the desired density, Addovate SM can be used simultaneously (at dosages of 1.0 - 4.0 Parts by weight Addovate SM)
On-site casting:
Continuous production of building boards with flexible and rigid or metal facings
Packing of Addocat DB:
Metal cans, contents 50 kg
Metal drums, contents 180 kg
Plastic container, contents 900 kg
Storage stability of Addocat DB:
When Addocat DB is stored in firmly closed original containers at about 20 °C, a shelf life of 12 months can be expec ted.
Prolonged storage, especially at temperatures above 30 °C, may discolor the product, even in closed containers.
This, however, does not impair the catalytic effect.
