摘要:
A coated polymer film, such as a coated polyester film, is disclosed. In one embodiment, the coated film may be used as a substrate for digital printing. In one embodiment, the coating contains an anionic anti-static agent comprising a sulphonated copolyester resin. In an alternative embodiment, the coating contains an anti-static agent comprising an organometallic, such as an organo zirconate, in combination with metal oxide particles. The metal oxide particles may comprise nanoparticles. In one embodiment, the coating can further contain a print enhancing agent and an adhesion promoter.
摘要:
A method for producing a component includes a) providing at least two preforms each made of a carbon composite material, b) joining the at least two preforms at least at one respective connecting surface to form a composite, in which a joining compound is introduced between the joining surfaces of the preforms and then cured and the joining compound contains silicon carbide and at least one polymer adhesive, and c) siliconizing the composite to form the component. A component, such as an optical component produced thereby, is also provided.
摘要:
The present disclosure relates to acrylic adhesive emulsions comprising a core-shell polymeric component comprising an inner core and an outer shell containing at least one pendent functional group; a polyfunctional component capable of reacting with at least one of the pendent functional groups on the outer shell; wherein the inner core is free of functional groups reactive with the pendent functional groups on the outer shell; and wherein the pH of the emulsion is 6.5 or less; and wherein the emulsion is a fast-setting, one part, aqueous, adhesive. Bonded articles made therefrom, and methods of bonding articles using these emulsions are also disclosed.
摘要:
The invention relates to a new binder composition which is particularly suitable for the manufacture of composite materials utilizing such new binder composition in the required nonwoven materials. Composite materials using such new binder composition in their nonwoven part are suitable, in particular, for composites materials for interior construction, for linings, floor coverings, and for the manufacture of furniture and similar products.
摘要:
Formaldehyde-free binder compositions are described that include an aldehyde or ketone, an organic anhydride, an alkanol amine, and a nitrogen-containing salt of an inorganic acid. The binder compositions may be applied to fibers, such as glass fibers, to make formaldehyde-free, fiber-reinforced composites. Methods of making fiber-reinforced composites are also described, where such methods may include mixing an alkanol amine with an organic anhydride to make a first mixture, and adding a reducing sugar to the first mixture to make a second mixture. A nitrogen-containing salt may be added to the second mixture to make a binder composition, which may be applied to fibers to form a binder-fiber amalgam. The amalgam may be heated to cure the binder composition and form the fiber-reinforced composite.
摘要:
An insulating substrate having a layer of an adhesive composition comprising (A) a modified phenolic resin and (B) acrylonitrile-butadiene rubber on at least one surface of a substrate is suitable for producing printed circuit boards having excellent solder heat resistance by an additive process.
摘要:
The present invention relates to an anti-migratory (as respects impregnated porous sheet members) phenol-formaldehyde resole resin in water emulsions. The emulsion is rendered anti-migratory (when impregnated into paper) through the addition thereto of an anti-migratory agent selected from the group consisting of polyelectrolytes, certain salts of inorganic acids, and combinations thereof. The composition is especially useful in the impregnation of filter paper.
摘要:
A readily dryable adhesive binder for particulated rubber and/or plastics compositions comprising from 1% to 10% by weight of a water-solubleformaldehyde polycondensation resin, from 0.5% to 5% by weight of formaldehyde or a compound liberating formaldehyde, and from 85% to 98.5% by weight of a film-forming plastics dispersion; as well as a composition forming a resilient covering comprising from 40% to 75% by weight of particulated rubber and/or plastics and from 25% to 60% by weight of the above adhesive binder.
摘要:
A method for fanning multi-ply sheets into units thereof, which comprises applying the adhesive composition to one side of a stack of multi-ply sheets, e.g., pressure-sensitive copying sheet units, and separating each unit of the sheets.
摘要:
Disclosed are liquid, curable adhesives having a pH of less than 3.5 and comprising an aldehyde condensation polymer and a finely divided metal selected from aluminum and iron. Such adhesives are particularly useful for application to cellulosic substrates such as wood. When the cured adhesive is subjected to hydrolytic conditions, the finely divided metal reacts with hydrogen ions leached from the adhesive and thereby prevents or markedly reduces degradation of the cellulosic substrate.
