09732235 · 2017-08-15 · ·

A self-healing coating composition for use on metals includes a polyurea, an epoxy ester unsaturated resin, a combination of amine terminated siloxane and epoxy terminated siloxane and an organoclay. The polyurea is a water-soluble, aromatic polyurea and likewise, the epoxy ester is a water-soluble, aromatic epoxy ester. The coating composition is formed in a non-volatile solvent, such as N-Methylpyrrolidone. It can be applied to a metal surface and cured at room temperature to form a coating that is resistant to corrosion. Further the coating self-heals in a manner similar to a chromate coating.

Immobilizing flexible stowage containers

A unique flexible container combination comprises a viscoelastomeric thermoset overlay disposed upon a flexible supportive base. Desirably, the viscoelastomeric thermoset overlay possesses exceptional adhesive, cohesive and releasability properties. In some embodiments, the flexible container combination can also exhibit antipathogenic, cleansability and/or reusability properties. The flexible container combination can maintain an adhered stowable item in an immobilized position until intentionally removed therefrom by a user. In some embodiments, the flexible container combination can be folded or rolled into a rolled-up configuration.

Fiber-reinforced resin, process for producing same, and molded article

(A) A reinforcing fiber, (B) a resin particle, and (C) a matrix resin are combined to prepare a resin composition which improves a reinforcing effect by the reinforcing fiber. The reinforcing fiber (A) contains a carbon fiber. The resin particle (B) contains a semicrystalline thermoplastic resin, the semicrystalline thermoplastic resin in the resin particle (B) has an exothermic peak in a temperature range between a glass transition temperature of the semicrystalline thermoplastic resin and a melting point of the semicrystalline thermoplastic resin, the peak being determined by heating the resin particle (B) at a rate of 10° C./min. by differential scanning calorimetry (DSC), and the resin particle (B) has an average particle size of 3 to 40 μm. The semicrystalline thermoplastic resin may be a polyamide resin having a melting point of not lower than 150° C. (particularly, a polyamide resin having an alicyclic structure and a glass transition temperature of not lower than 100° C., or a polyamide resin having a γ-type crystal structure or a degree of crystallinity of not more than 50%). The matrix resin (C) may be a thermosetting resin.
