Detailed Description

Carbodiimide stabilizer (Product code:VC-201) CAS:2162-74-5

 

Function

VC-201 is an active hydrolysis resistant agent for polyester polyurethanes produced by hot casting as well as for adhesives based on polyester polyurethane. VC-201 Powder 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 0.5 part by weight VC-201 Powder to 100 parts by weight polyester polyol approximately doubles the resistance to hydrolysis.

 

Additions of 2.0 parts by weight to otherwise unprotected polyester poly- urethane elastomers increases their resistance to hydrolysis approximately

 

four times. These data were given by tests, conducted at 70 °C and 80 % relative humidity. As VC-201 Powder tends to bloom in certain goods, the addition should not exceed 2 parts by weight (on 100 parts polyester polyol). Prior tests should always be carried out to determine the most suitable addition, however.

 

To be most effective, VC-201 Powder should be added to the polyester polyol during the warming-up period, starting at a minimum temperature of 50 °C (120 °F), to a maximum temperature of 120 °C (250 °F). As VC-201 Powder 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. VC-201 Powder may slightly accelerate the cross linking reaction (polyester polyol/iscoyanate). This can be counteracted by adding a very small amount of an organic acid (e.g. citric acid).
