VQM 800 Vinyl siloxane and QM resin Hanse Chemie Silicone (Si) >> MQ type Silicone (Si) >> Vinyl SEALANT ADHESIVE Pure silicone elastomers have only moderately good mechanical properties, that can usually be improved by the addition of suitable fillers like fumed silica or quartz. Another way to improve the mechanical resistance of silicone elastomers is to add so-called QM resins. These consist of Q units (SiO 4/2) and M-units (Me3SiO1/2) and are usually soluble in vinyl siloxanes. The hanse chemie VQM series products are preparations of QM resins and vinyl siloxanes, with the M-units containing vinyl groups. This makes these products especially suitable for producing transparent formulations with good characteristics Preparations of QM resin and vinyl siloxane. Used as additives in 2-part silicone formulations. Produces transparent formulations with good characteristics. Improves mechanical resistance of silicone elastomers.
