Processing Advantages Konson® MgO-70 is easy to incorporate and disperses quick and homogeneously in the mix. Dusting and absorption of humidity are effectively reduced in the pre-dispersed,polymer bound form. For optimal results it is recommend to add Konson® MgO-70 at the beginning of the first mixing stage. Use Characteristics In halogenated elastomers such as CR, CM, and CSM as well as chlorinated sulfur factis magnesium oxide acts as an acid acceptor and curing activator. It also improves scorch behavior of such mixes.
Dosage levels 2 – 4 phr
Applications Curing activator and acid acceptor particularly suitable for polychloroprene rubber (CR) and adhesives
