Oc 144.0 Heating loss 0.40 Ash 0.40 Residues on sieve(150m), % 0.10 Properties:grayish-white powder. No taste, no poison. Densiy is 1.08-1.19. Soluble in acetone, ethyl acetate, benzene, alcohol, slightly soluble in ccl4; insoluble in water and gasoline. Application:used as a secondary accelerator with thiazoles and sulphenamides in nr and sbr compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. Dpg can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process Packing: 25kg in kraft paper bag with pe bag inside, or 25kg in plastic woven bag with pe bag inside, or as customers request. Storage:keep in a cool, well-ventilated place. The shelf life is 2 years. Notes: the products could be oil coated powder, as per customers request.
