Technical Details & Test Data
- Technical Data
Stabaxol® I is normally being dissolved in the polyester polyol; alternatively, it may be added to the pre-polymer (only with terminal OH-groups). An addition of 1 part by weight Stabaxol® I to 100 parts by weight polyester polyol increases the resistance to hydrolysis up to 7 times. This data was established by tests conducted at 80 % relative humidity. Stabaxol® I gives the best results when added in a concentration of up to 2 parts by weight to otherwise unprotected polyester polyurethane elastomers.
Hydrolytic Stability of Polyester based Polyurethane Elastomers
For adhesives we recommend to add 1-2 parts by weight Stabaxol® I to 100 parts by weight adhesive. Prior tests should always be carried out to determine the most suitable dosage, however. To be most effective, Stabaxol® I should be added to the polyester polyol during the warming-up period, starting at a minimum temperature of 50 °C (122 °F), to a maximum temperature of 120 °C (248 °F). As Stabaxol® I does not disperse readily (it may float undissolved on the surface), it should be stirred intensively. The necessary time and temperature to complete the reaction is shown in the graph below.
Acid Reduction with 1% Stabaxol I in Polyester Polyol
Stabaxol® I may slightly accelerate the crosslinking reaction (polyester polyol/iscoyanate). This can be counteracted by adding a very small amount of an organic acid (e.g. citric acid).
