elongation) to the current conventional HDS (Hi-Sil HDP-320G silica)/in-situ silane addition compound produced in this 16 liter pilot plant intensive mixer study.
An adjusted model passenger tread compound containing A-400G silica using 8% more filler, 43% more sulfur, 88% more CBS and 75% less toxic DPG produced a cure profile that was equal to or better than the cure profile associated with a typical current conventional HDS/in-situ silane addition compound.
C, MW 24) in an amount of 2% to 40% by weight, wherein at least a portion of the ethylenically unsaturated groups are incorporated by reacting an isocyanate group with the reaction product of (meth)acrylic acid with B-caprolactone and wherein the preceding percentages are based on the solids content of the polyisocyanate addition compounds
and wherein fluorine is incorporated by reacting an isocyanate group with a compound containing two or more carbon atoms, one or more hydroxyl groups and one or more fluorine atoms to form urethane groups and optionally allophanate groups, provided that more than 50 mole percent of the groups that chemically incorporate fluorine into the polyisocyanate addition compounds
are urethane groups.
