Description of Addovate DD 1092:
Additive for the production of cellular elastomers based on NDI/Polyester technology.
Chemical Composition of Addovate DD 1092:
Mixture of emulsifiers based on fatty acid ester.
Addovate DD 1092 is a liquid emulsifier and foam stabilizers used for the production of cellular elastomers based on NDI/polyester technology.
Addovate DD 1092 retards the foaming reaction.
Crosslinking is achieved by evenly stirring the cross-linker into the pre-polymer which has been cooled to about 90°C.
Addovate DD 1092 has a shelf life of 4 months.

Applications of Addovate DD 1092:
Addovate DD 1092 is an additive for the production of cellular elastomers based on NDI/Polyester technology.
Addovate DD 1092 is a liquid emulsifier and retards the foaming reaction.
After a prepolymer has been manufactured on the basis of polyester polyol, NDI and additives (e. g. citric acid, castor oil and Stabaxol), the reaction is completed by the addition of crosslinker.
Crosslinking is achieved by evenly stirring the crosslinker into the prepolymer which has been cooled to about 90 °C.
To manufacture the crosslinker, Vulkollan 2001 KS is heated to 40 - 50 °C and the specified additives are to be stirred in vigorously.
This mixture must be stored in sealed containers at a temperature of 45 - 50 °C and used within 8 hours.
Addovate DD 1092 is an additive for the production of cellular Vulkollan.
Crosslinker Formulation:
Vulkollan 2001 KS 10
Addovate SM 2.15
Addovate DD 1092 0.215
Addocat PP 0.0215
Refurbishing of Addovate DD 1092:
If a specific pH value (e. g. 7 - 8) is required but the pH value of the product has dropped to pH 5 - 6 due to excessively warm storage temperatures, it is possible to restore the original pH value.
To achieve this 50 - 100 g monoethanol amine per 50 kg Addovate DD 1092 should be added, followed by homogenization by stirring.
Packaging of Addovate DD 1092:
• Metal cans, contents 50 kg
• Metal drums contents 200 kg
Storage conditions of Addovate DD 1092:
Addovate DD 1092 is to be stored in a cool and dry place.
When Addovate DD 1092 is stored in firmly closed original containers a shelf-life of 4 months from manufacturing date at pH 7 - 9 can be expected only at temperatures < 6 °C.
Higher storage temperatures reduce the pH-value of Addovate DD 1092.
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.
Handling of Addovate DD 1092:
Consult the safety data sheet for relevant safety data & references as well as possibly necessary warning labels.
