    Abstract: A composite wire or thread-based reinforcement is coated with rubber and may be used for reinforcing a finished rubber article, such as a tyre. The reinforcement includes one or more textile or metallic reinforcing wires or threads, and a coating rubber that coats each wire or thread. The coating rubber is formed of a rubber composition that includes at least one diene elastomer, a reinforcing filler, between 10 and 150 phr (parts by weight per hundred parts of elastomer or rubber) of a platy filler, and a crosslinking system. The coating rubber has improved water-barrier properties, thus giving the composite wire or thread-based reinforcement better protection against corrosion or ageing due to penetration of water, for example through tyre tread.

    Abstract: To improve tensile strength without impairing flexibility and adhesion to concrete, and to form a thick coating in a surface layer part for preventing a basis material from being exposed by damage to the coating, a method of forming double coatings on a prestressing strand includes a primary painting process after a pre-treatment process, in which a resin coating is formed only at the surface layer, a secondary painting process in which respectively individual state resin coating is formed on an outer peripheral face of each of the core wire and surrounding wires under a loosened and separated state, thereby forming a double coating for each surrounding wire, and a finishing process of tightening and retwisting the surrounding wires about the core wire to an original state. The obtained prestressing strand has the double coating portions only at the surface layer and sufficient flexibility and adhesion to concrete.
