WACKER® IM 22
WACKER® IM 22 is a polydimethylsiloxane having polyether groups in α,ω-position.
Due to their terminal functional groups WACKER® IM 22 is a valuable reactive silicone intermediate, with the typical reactivity of the corresponding functional groups, i.e. esterifications, transesterifications and addition reactions with isocyanates. This results in manifold possibilities for further chemical modification and for the silicone modification of organic polymers.
Modification of organic systems with polydimethylsiloxanes results in a change of the properties of the system. Typical properties of the polydimethylsiloxane backbone are, for example:
- insertion of hydrophilic properties
- low surface tension
- good softening effects
- high chemical stability
- improved low-temperature stability
- very good low-temperature flexibility
WACKER® IM 22 are used in following applications of the textile auxiliary industry:
PUR-fine coating: plastifier, softener
artifical leather: paint additive
WACKER® IM 22 can be used neat, from solution, or emulsion. Due to its polyglycol groups WACKER® IM 22 shows hydrophilic properties and improved solubility in polar organic systems, e.g. ethanole and isopropanole.
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
