Application

RJ-171SO is an excellent adhesion promoter between inorganic fillers (e.g. kaolin, MDH, ATH) and organic polymers (e.g.EPDM, EVA, PE).

The high boiling point of RJ-171SO, together with its high flash point, gives it outstanding advantages with respect to safety and handling during processing. From an environmental viewpoint it should be noted that the amount of released hydrolysis methanol (VOC) is significantly reduced compared to monomeric vinyl silanes. 

Packing

RJ-171SO is available in 200kg iron drums, 1000kg IBC drums, or other packing on request.

Storage

Transport as non-hazardous chemicals. Store in original container only. Keep container tightly closed and store in a cool, well ventilated place.

Shelf life

Original characteristics remain intact for 1 years, if kept in recommended storage.
