摘要:
Suspension agent for synthetic resin powders comprising an aqueous emulsion wherein there is contained, in a concentration of about 1-7.5 percent by weight:(A) a mixture of about 95-40 molar percent of an aminoamide of the general formula ##STR1## wherein R represents a saturated or unsaturated hydrocarbon group having 13-19 carbon atoms,n represents an integer of between 2 and 6, andR.sub.1 and R.sub.2 represent alkyl groups having 1-3 carbon atoms; and(B) about 5-60 molar percent of a fatty acid or mineral acid salt of this aminoamide.
摘要:
Adhesion of thermoplastic elastomers, such as unvulcanized styrene-butadiene rubber, to a solid substrate is obtained by using a primer containing a tackifier component, such as hydrogenated rosin or a coumarone-indene resin, and an amino-functional trihydrolyzable silane, partial condensates and hydrochloride salts thereof in which the amino-functionality is in the form of a primary or secondary amine.
摘要:
An adhesive composition comprises chlorobutyl rubber, an unsaturated ethylene-alpha olefin polymer of high molecular weight (as defined), carbon black, a liquid isobutene polymer, an ethylene alpha-olefin copolymer of low molecular weight (as defined), a tackifying resin and a sulphur vulcanisation system, each component being present in specified proportions. The adhesive composition is particularly useful in the preparation of an article of manufacture comprising at least two sheets of vulcanised EPDM rubber compositions, the edge portion of the sheets being adhered together at the interface by means of the adhesive composition which has been vulcanised after bringing said edges together.

WHEREIN RI IS HYDROGEN, METHYL OR ETHYL, R'' IS FLUORINE, -CF3 OR -(CF2)NH, AND N IS AN INTEGER FROM 1 TO 3 HAVE BEEN FOUND TO BE USEFUL ADHESIVES WHICH WHEN APPLIED AS MONOMERS TO ADHERENDS RAPIDLY POLYMERIZE IN THE PRESENCE OF EVEN SMALL AMOUNTS OF E.G. MOISTURE TO FORM STRONG BONDS. THE MONOMERS ALSO POLYMERIZE TO FILMS AND CAN BE USED BIOLOGICALLY AS HEMOSTATICS AND TISSUE ADHESIVES.

The invention relates to a method for surgically adhering living tissues and effecting hemostasis therein by means of a rapidly polymerizing composition which comprises alkoxyalkyl 2cyanoacrylates.
摘要:
A dielectric welding film capable of providing excellent adhesiveness to a variety of adherends in a short period of dielectric heating, and an welding method using the dielectric welding film are provided. The dielectric welding film is configured to adhere a pair of adherends of the same material or different materials through dielectric heating, the dielectric welding film including a first thermoplastic resin as an A1 component having a predetermined solubility parameter, a second thermoplastic resin as an A2 component having a solubility parameter larger than the solubility parameter of the first thermoplastic resin, and a dielectric filler as a B component. The welding method uses the dielectric welding film.
摘要:
An article includes a substrate including a bonding surface area, a first adhesive disposed on the bonding surface area in a first discrete pattern, the first adhesive comprising a hot melt adhesive, and a second adhesive disposed on the bonding surface area in a second discrete pattern that is complementary to the first discrete pattern, wherein the first discrete pattern comprises about 1% to about 25% of the bonding surface area and the second discrete pattern comprises a balance of the bonding surface area.
摘要:
The present invention relates to a hot melt adhesive composition comprising at least one particular aldehyde scavenger, and the use of said aldehyde scavenger(s) to remove or reduce the volatile organic compound(s) (VOC), particularly volatile aldehyde(s) of a hot melt adhesive composition.The hot melt adhesive compositions according to the invention emit low odor during and after their manufacture and application, and are thus particularly useful to manufacture low odor disposable nonwoven absorbent articles.
