Hydroxy polysiloxanes


Polymer OR 501 is a special silicone polymer for non-staining condensation-curing silicone formulations. This polymer is recommended in particular for low-modulus sealants and adhesives when the use of silicone oils as plasticizers is not advised, e. g. in natural stone applications.
