Abstract: A pneumatic tire (10) has an inner shoulder (11), an outer shoulder (12) and a tread (13) therebetween. The tread includes a plurality of circumferential grooves 30, 32, 34, 36 38) dividing the tread into a plurality of ribs including inner and outer shoulder ribs (14, 14?), inner and outer intermediate ribs (18, 18?) between the shoulder ribs and a central rib (16) between the intermediate ribs. First sipes (20) are provided in the shoulder ribs and the central rib. Each first sipe has an interlocking shape. Second sipes (22) are provided in the intermediate ribs. Each second sipe has a shape different from that of the first sipes. Third sipes (24) are provided in the intermediate ribs. Each third sipe has a shape different from that of the first and second sipes.

Abstract: The present invention is directed to a multiple component coating composition comprising (a) a film forming binder component having isocyanate reactive groups; (b) a stable polyisocyanate solution comprising organic liquid and up to 30% by weight, based on the weight of the polyisocyanate solution, of a polyisocyanate having reactive isocyanate groups selected from an aromatic polyisocyanate having tertiary isocyanate groups or a (meth)acrylic polymer containing reactive isocyanate groups; and (c) optionally, a tinting composition comprising pigment, a dispersing agent and an organic liquid carrier; whereby components (a), (b) and (c) are blended together before application to a substrate and after application to a substrate the composition is cured to form a finish. The present invention is also directed to a method of producing a finish on a substrate and to the resulting coated substrate.

Abstract: This invention provides for a two-pack solvent based coating composition that cures in two stages when applied over substrates. The first stage of the cure takes place rapidly under ambient conditions to produce a coating surface that can be readily sanded or buffed. Thereafter, over a period of days a second stage cure takes place to produce a coating having excellent coating properties. Thus, a coated component, such as automotive body, can be speedily moved out from a spray booth without affecting the surface quality of the coated surface. As a result, coating operation productivity can be increased. The aforedescribed dual cure properties of the coating composition result from including in a binder component of the coating composition an acrylic polymer having secondary amine and hydroxyl functionalities. The composition is most suited for use in automotive refinish applications.
