Provided is an application tool that allows reduction of an amount of waste by using no masking sheets, and can easily form a coated portion such as an antislip protrusion with reduced variation in a short time period. The application tool includes a support plate and a plurality of application bodies disposed at the support plate so as to protrude with height positions of the tips aligned with each other. A tip recess is disposed at the tip portion of each of the plurality of the application bodies as a holding recess for holding coating liquid.

Application tool

An anti-slip structure comprising a plurality of anti-slip projections that protrude outwardly from a floor surface and are arranged so as to be mutually isolated, the anti-slip structure being such that the anti-slip projections are of circular dome-like three-dimensional shape and are cured bodies produced by curing a composition for anti-slip treatment comprising a curable resin. This anti-slip structure causes a floor surface comprising ceramic tile, tile made of stone material, or the like to be imparted with excellent anti-slip capability without impairing the lustrousness, beauty, design characteristics, or cleanability of the floor surface.

Anti-slip structure and composition for anti-slip treatment

A precoated skin material for an automobile interior part comprising (a) a skin material for an automobile interior part and (b) a one-pack type thermally crosslinkable polymer composition comprising (i) a thermoplastic olefinic polymer having a carboxylic acid group or an acid anhydride group, (ii) a latent curing agent, (iii) a carbonyl compound as a solvent and (iv) a tackifier, which composition is coated on the back surface of the skin material, wherein the latent curing agent is a solid polyamine having a melting point of 80 to 200&deg; C. which form hydrolyzable reaction products by a condensation reaction with the carbonyl compound used as the solvent, or a hydrolyzable reaction product of a diamine with a carbonyl compound.

Precoated skin material for automobile interior part

A two-part polyurethane adhesive which comprises a main component comprising a hydroxyl-terminated saturated polyester resin or a polyester urethane rubber prepared by reacting said hydroxyl-terminated saturated polyester resin with a diisocyanate compound, and a curing agent comprising a urethane prepolymer having an active isocyanate group which is prepared by reacting a hydrogenated hydroxyl-terminated polybutadiene with an excess amount of a polyisocyanate. Said polyurethane adhesive is useful for adhering a polyolefin base material and a covering material for the production of automobile interior parts.

Polyurethane adhesive

A moisture-crosslinkable primer which comprises a solution of a hydrogenated polybutadiene into which has been introduced a silyl group of the formula: ##STR1## wherein R is an alkyl group having 1 to 5 carbon atoms, R' is an alkoxy group having 1 to 5 carbon atoms or a halogen atom, and n is an integer of from 1 to 3, in an organic solvent, which has excellent heat-resistant adhesion and durable adhesion and is useful for adhering between polyolefinic substances or between polyolefinic substances and other organic substances.

Moisture-crosslinkable primer for polyolefins

The invention relates to a moisture-curable primer composition comprising a reaction product between a maleic anhydride-modified styrene-ethylene-butene-styrene copolymer and an epoxysilane compound. This primer composition is particularly useful for the bonding of polyolefin adherents.

Moisture-crosslinkable primer composition

A two part primer composition comprising a main component comprising at least one styrene-ethylene-butene-styrene block copolymer or styrene-ethylene-propylene-styrene copolymer, said copolymer being copolymerized with maleic anhydride hydrogenated, and an amine catalyst, and a curing component comprising an epoxy resin having two or more functional groups, which has excellent heat-resistant adhesion and durable adhesion and is suitable for adhering between polyolefinic substances or between an polyolefinic substance and other organic substance.
