    摘要: The present invention is a composition for forming seals. The composition includes a base material and a hydrogel. The base materials is preferably an elastomer or a thermoplastic. Seals formed with the composition are particularly suited for use in a wellbore environment. The inclusion of hydrogel in the seals allows the seals to be manipulated or altered through certain environmental factors. For instance, temperature, oil/water ratio, pH and the electronic field may all be used to alter the characteristics of the hydrogel. In this way, the seal may be caused to swell in response to a specific stimulus, thereby preventing or sealing a leak without requiring additional work or input from the operator.

    摘要: Photocurable filling compounds for closing the gaps which result between the end or edge regions of gravure printing plates when the latter are clamped on forme cylinders consist of a homogeneous, solvent-free, photopolymerizable mixture which is free-flowing at room temperature and contains from 10 to 90% by weight of one or more hydrophilic, polar, photopolymerizable, ethylenically unsaturated low molecular weight compounds, from 5 to 65% by weight of one or more polymeric binders which are resistant to toluene-containing, gasoline-containing, ketone-containing and/or ester-containing solvents and are compatible with the photopolymerizable low molecular weight compounds, from 0.01 to 10% by weight of one or more photoinitiators and from 0 to 70% by weight of further additives and/or assistants.

    摘要: Described is a UV-curable sealant composition, which is preferably a one part sealant. The one part sealant is made from urethane acrylate, acrylate ester, precipitated silica, and photoinitiator. More specifically, the one part sealant is made from about 15-35 weight percent aliphatic and/or alicyclic urethane acrylates, about 40-70 weight percent of acrylate esters, about 0-10 weight percent of precipitated silica, and about 3-8 weight percent of photoinitiator. Also described are methods of applying UV-curable sealant composition to a surface such as a floor and UV curing the UV-curable sealant composition, thereby extending the life of the surface.

    摘要: The invention relates to an optionally foamed sealing composition for preformed seals which can swell when treated with water. The invention also relates to a method for the production thereof out of natural rubber and/or elastomers with a matrix comprised of natural rubber/elastomer components and particle-shaped water absorbing material stored therein. The water absorbing material is a combination of (A) polysaccharide(s) selected from cellulose, starch, starch derivatives removed from grafted starch, amylose, amylopectin, dextran, pectin, inulin, chitin, xanthan, alginic acid, alginates, carrageenan, pustulan, callose, laminarin, guluronic acid, pullulan, lichenin or mixtures of the same with (B) a highly water absorbent synthetic polymer selected from polymers based on (meth)acrylate, poly(meth)acrylic acid and the salts thereof, polyacrylamide, polyalcohols or copolymers of said synthetic polymers. The invention also relates to additional cross-linking and processing auxiliary agents and to property improving agents. It is possible to securely seal superstructures, substructures, tunnels and canals with the assistance of the inventive sealing compositions.
