WACKER® IM 35
WACKER® IM 35 Wacker IM 35 is a linear, alpha-omega functional Polydimethylsiloxane having a chain consisting of approx. 50 dimethyl siloxane units. Both epoxygroups on the end of the chain are linked by Si-C bonds; these bonds are stable towards hydrolysis. The epoxy-groups have no steric hinderance and can by this undergo all chemical reactions of this group.

Processing
WACKER® IM 35 is insoluble in water and can therefore directly only be dissolved with organic solvents. Emulsification is possible, however the epoxy group needs to remain untouched by this process. Nucleophilic agents will open the epoxy-ring.
