POLYURETHANE OR POLYURETHANE-UREA AQUEOUS DISPERSION, PREPARATION METHOD THEREFOR, AND USE THEREOF
A self-crosslinkable polyurethane or polyurethane-urea aqueous dispersion, a preparation method therefor, and a use thereof. Side chains of the polyurethane or polyurethane-urea contain non-sterically-hindered siloxy groups. During the drying and activation of the aqueous dispersion, the siloxys in the side chains are hydrolyzed and crosslinked with each other to increase the cross-linking density, significantly improving the heat resistance, the humidity resistance, and other properties of an adhesive obtained therefrom. The aqueous dispersion itself has a good stability. In addition, an application system based thereon has an excellent stability and a long storage time. The aqueous dispersion is suitable for the preparation of high quality paints and sealants, especially adhesives.
PRESSURE-SENSITIVE ADHESIVE TAPE
The present invention relates to a pressure-sensitive adhesive tape comprising a backing layer having a first and a second surface; and a first pressure-sensitive adhesive layer affixed to the first surface; wherein the first pressure-sensitive adhesive layer has an adhesive strength of 2.0 N/10 mm to 9.0 N/10 mm in absence of a solvent and the pressure-sensitive adhesive tape has a tensile strength in longitudinal direction of 45 N/15 mm to 80 N/15 mm.
COMPOSITE AND POWER TRANSMISSION BELT
A composite comprises: at least one reinforcing element (10), an adhesive layer (14) made from an adhesive composition and coating the reinforcing element (10), an elastomeric bonding layer (16) made from an elastomeric bonding composition and directly coating the adhesive layer (14), and an elastomeric body made from an elastomeric matrix and embedded in which is the reinforcing element (10) coated with the adhesive layer (14) and with the elastomeric bonding layer (16). The adhesive composition comprises a phenol-aldehyde resin based: on an aromatic polyphenol comprising at least one aromatic ring bearing at least two hydroxyl functions in the meta position relative to one another, the two positions ortho to at least one of the hydroxyl functions being unsubstituted; and on an aromatic aldehyde bearing an aldehyde function, comprising at least one aromatic ring.
Pretreatment of substrates that have unsaturated units
A method for treating substrates, including applying a composition, which includes at least one latent alkyl borane and is substantially free of decomplexing agents for the latent alkyl borane, to a substrate (1) that has a material having unsaturated units, applying a radically curable substance to the substrate (1) pretreated with the latent alkyl borane, and allowing the radically curable substance to cure in order to form a composite structure. The method is suitable in particular for applying paints, coatings, or sealing materials/filling materials to substrates, such as EPDM, NBR, and SBR, and for adhesively bonding such substrates. Composite materials adhesively bonded accordingly are distinguished by especially firm adhesion of the adhesive to the substrate, wherein conventional adhesives can be used, which have optimized properties with regard to the storage stability, open time, and cure time thereof.
Double coated tape
Provided are double-coated tapes that include, in the following order: a first pressure-sensitive adhesive layer; a first plastic skin layer; an elastic base layer; a second plastic skin layer; and a second pressure-sensitive adhesive layer. The provided double-coated adhesive tapes can provide a combination of high bond strength, reworkability, and high impact and shock resistance, and can be easily converted using a die cutting process.

RESIN-RUBBER COMPOSITE
A resin-rubber composite in which a polyamide-based resin-molded product or a polyphenylene sulfide-based resin-molded product is directly vulcanization-bonded to a peroxide-crosslinkable nonpolar rubber composition, which forms a rubber layer, without interposing an adhesive, wherein both resin-molded products have a polymerized film with a radical, which is formed by activating the surface of the product, in the case of polyamide-based resin-molded products, by low-pressure plasma treatment by a microwave method using inert gas, or by activating the surface of the product, in the case of polyphenylene sulfide-based resin-molded products, by low-pressure plasma treatment by a microwave method using active gas, and then performing low-pressure plasma treatment by a microwave method using a hydrocarbon-based monomer in both cases. The resin-rubber composite can be effectively used for drum seals, automobile parts such as side cover seals for transmissions, anti-vibration rubber, resin rubber laminate hoses, and the like.
