ADDOCAT 201

CAS Number: 77-58-7

Dibutyltin dilaurate (DBTDL) 

Addocat 201 is a standard strong multi-purpose gelling catalyst.

Addocat 201 is a polyurethane catalyst based on an organometal compound, specifically Dibutyltin dilaurate (DBTDL).  
Addocat 201 strongly activates the gelling (crosslinking) reaction in rigid polyurethane foams, elastomers and coatings.

Function of Addocat 201:
Catalyst for the production of polyurethanes, e.g. integral skin foams, rigid spray foam, cold-curing cast elastomers etc.

Addocat 201 is dibutyl tin dilaurate. 
Addocat 201 acts as a catalyst for the production of polyurethanes, e.g. integral skin foams, rigid spray foam, cold-curing cast elastomers etc. 

Addocat 201 considerably reduces the cure time. 
Addocat 201 has a shelf life of 12 months.

Product information about Addocat 201:
Addocat 201 catalyses the crosslinking reaction strongly.

Integral skin foam (flexible and semi-rigid):
In the production of integral skin foam Addocat 201 is used at 0.02 - 0.1 p.b.w. in addition to tertiary amines, such as Addocat 105 , of which the proportion used is 1.0 - 2.0 p.b.w. on 100 p.b.w. polyol. Addocat 201 considerably reduces the cure time.

Rigid spray foam:
Addocat 201 is used at 0.2 - 0.4 p.b.w. on 100 p.b.w. polyol together with 0.5 - 2.0 p.b.w. tertiary amine, e.g. Addocat 726 b and / or triethylamine, to accelerate the cure of rigid spray foam systems.

Cold-curing cast elastomers:
Addocat 201 is a highly effective catalyst for cold-curing cast elastomers. 
Even small additions (0.02 - 0.1 p.b.w. on 100 p.b.w. polyol) greatly reduce the cure time (demoulding time).

Packing of Addocat 201:
Plastic cans, contents 50 kg

Storage stability of Addocat 201:
When Addocat 201 is stored in firmly closed original containers at 20 °C, a shelf life of 12 months can be expected.

Handling of Addocat 201:
Consult material safety data sheet (MSDS) for additional handling information for Addocat 201.
