An automatic injecting type paste form heat-blowing injection composition comprising a partially crosslinked rubber, an unvulcanized rubber, a crosslinking agent, a plasticizer, a thermoplastic resin, an epoxy resin and a latent curing agent thereof, and a blowing agent. This composition can be used in a injecting and soundproofing method comprising forming an insulation wall by heating and foaming of a injection composition in a closed section of an automobile body part having a closed section frame which is produced by press molding in a body welding step of an automobile manufacturing line, and it has a good anti-stringy property and suffers form less sagging during heating and foaming.

A two-pack curable composition of the present invention comprises plastisol liquid A which comppounds a thermoplastic resin and a plasticizer, and liquid B which compounds a gelling agent and is characterized in that it has a sprayable viscosity when liquids A and B are mixed and gels within 30 seconds to 60 minutes after application. This two-pack curable composition can be applied in a body-welding step of an automobile manufacturing line as a body or seam sealer (for water-proofing, air-tightness, dust-proofing or rust-prevention of welded areas), an underbody coating (for anti-chipping), or an adhesive.

The present invention provides a coating type reinforcement composition of sheet metal which can be applied under warming for ensuring satisfactory levels of tensile rigidity and resistance to dent of a thin sheet metal mainly due to weight reduction of an automobile body, or for collision safety, and which improve a bending strength and a rigidity of the sheet metal without causing a distortion to the sheet metal. The coating type reinforcement composition of sheet metal according to the present invention comprises a liquid epoxy resin, a latent curing agent and an inorganic filler having an aspect ratio (L/D) of 5 or higher, an amount of the inorganic filler contained being 20 to 50% by weight and the composition being a viscous preparation with a high viscosity.
