WACKER® IM 11

WACKER® IM 11 is used in following applications of the textile auxiliary industry:

• Polyurethane finecoating: plastifier, softener
• Artifical leather: flow control agent for paints

Processing

WACKER® IM 11 can be used neat, from solution, or emulsion. Suitable solvents for WACKER® IM 11 are aliphatic and aromatic hydrocarbons, chlorinated hydrocarbons, esters, higher alcohols, and ketones.

• By functionalizing the polydimethylsiloxanes at the ends of the chain defined products with 2 organofunctions are obtained. The functional groups are bonded to the polydimethylsiloxane by chemically inert propylene spacergroups, which are stable to hydrolysis.
• Its terminal functional groups render WACKER IM 11 a valuable reactive silicone intermediate, which is useful for typical reactions with suitable functional groups of appropriate compounds, e.g. esterifications, transesterifications and addition reactions with isocyanates. This results in manifold possibilities for further chemical modification, for the synthesis of block copolymer systems or for the modification of organic polymers with silicone.
• 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:
  • Low surface tension
  • Good softender effects
  • High chemical stability
  • Excellent high- and low-temperature stability
  • Very good low-temperature flexibility
