Addocat® 105

• Addocat® 105 is one of the standard catalysts for polyurethanes.
• In foam production it activates both the blowing and the crosslinking reaction.
• Typical dosage of Addocat® 105 is 1.0 - 3.0 pphp.
• Conventional ether foam (molded and slabstock) Addocat® 105 serves mainly to promote the blowing reaction (0.3 - 0.45 pphp).
• It is used together with Addocat® So (0.1 - 0.3 pphp), which activates the crosslinking reaction. HR-foam (molded and slabstock)
• The reaction can be controlled with Addocat® 105 (0.3 - 1.0 pphp) in combination with Addocat® 108 (0.1 - 0.5 pphp).

Semi-rigid filling foam:

• It has been found advisable to use triethanol amine (up to 4.0 pphp) in addition to Addocat® 105.
• This improves the open cell structure.

Rigid foam:

• Sandwich panels (continuous & diskontinuous)
• Pipe insulation (diskontinuous)
• Appliance insulation
• On-site casting

Addocat® 105 gives rigid foams a tough and elastic skin, thus improving the adhesion of the foam to flexible and rigid facings.

It can be used alone and in combination with Addocat® 726 B and Addocat® PP.

Integral skin foam (flexible, semi-rigid, rigid):

Addocat® 105 (1.0 - 2.0 pphp) is used together with Addocat® 201 (0.02 - 0.05 pphp) to reduce the demolding times.

Cold-curing cast elastomers:

Addocat® 105 (0.1 - 0.5 pphp) is used when relatively long filling times are desired.

• Addocat® 105 is to be stored in a cool and dry place.
• When Addocat 105 is stored in firmly closed original containers at approx. 20 °C, a shelf-life of 24 months from manufacturing date can be expected.
• The contents have to be thoroughly homogenized before use.
• The containers should be resealed tightly after use to prevent contamination by impurities and exposure to moisture.
