Described herein is an automatic or automated process for injection molding of coated components, more particularly coated soles of plastic, where first of all the molding tool is lined with a release agent composition and, after flashing of this release agent composition, a composition for forming the component is injected. After crosslinking of these two compositions, the coated component produced is removed from the molding tool and subjected optionally to an aftertreatment.

A release agent composition for tire-molding contains: (A) 100 parts by mass of an organopolysiloxane containing at least two hydroxy groups bonded to a silicon atom in one molecule and having a viscosity at 25° C. of 10,000 mPa.Math.s or higher; (B) 10 to 100 parts by mass of an organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to a silicon atom in one molecule relative to 100 parts by mass of the component (A); (C) 10 to 10,000 parts by mass of water relative to 100 parts by mass of the component (A); and (D) 2 to 70 parts by mass of a polyvinyl alcohol relative to 100 parts by mass of the component (A). The release agent composition for tire-molding is excellent in release. Molding and vulcanizing tires repeatedly in succession a larger number of times without applying a release agent after once applying a release agent is realized.

A composite material shaped product manufacturing shaping die is used when manufacturing a composite material shaped product constituted by at least a resin composition and a fiber material. The composite material shaped product is formed by shaping, by the shaping die, a laminated body of prepregs each formed by impregnating the fiber material with the resin composition. The shaping die includes a die member having a shaping surface defining an outer surface shape of the laminated body. The shaping surface of the die member includes: a release coating covering the shaping surface; and a release agent layer formed on the release coating by applying a release agent to the release coating.

Provided are a pneumatic tire and a method for manufacturing the same. At least one sensor unit including a sensor that acquires tire information is fixed to a tire inner surface via an adhesive layer, and an amount of silicon in a release agent detected by fluorescent X-ray analysis at least in a fixing region for the sensor unit is from 0.1 wt % to 10.0 wt %.
