摘要： A coated abrasive which is advantageous for certain applications has at least two distinct layers of abrasive grits: a coarse outer layer and a finer inner layer. The median particle size of the grits in the outer layer is at least 150% of that of the inner layer grits. The grits may be adhered to the backing with adhesives compounded primarily of acrylates and cured by exposure to UV light. A product made in this way is effective for one step fining of plastic ophthalmic lenses.

摘要： Previous coated abrasives with adhesives suited to rapid, UV light initiated cure often had intractable curl problems. Therefore, such coated abrasives have been unsuited to precision finishing of workpieces with strict flatness or other curvature requirements, such as read-write heads for magnetic recorders or computer memories.This invention provides coated abrasives, having adhesives with cure initiated by UV light, which are suited to curvature control by the methods used conventionally for magnetic recording media. The preferred adhesive formulations include reaction products of 2-hydroxyethyl acrylate with polyol polyester oligomers capped with isocyanate end groups, alkoxylated diacrylated monomers, and N-vinyl pyrrolidone and other monomers with only one polymerizable unsaturated double bond per molecule, and sometimes also include nonpolymerizable thermoplastic polymers. The adhesives, with abrasives grain dispersed therein, are milled in special mills combining the actions of small milling media with large scale high speed agitation to reduce their viscosity to a workable level for gravure roll coating. The dispersion is then coated on plastic film backings and cured with UV lamps having a high spectral output in the near UV, the backing being kept cool during cure by contact with a cooled metal roll. The warm coated abrasive thus formed is finally shaped into accurately flat or other controlled curvature.

摘要： Coated abrasive material for fine finishing applications including second fining ophthalmic application, having patterned surface coating of abrasive grains dispersed in radiation-cured adhesive binder. The patterned surface coating is defined by a plurality of formations of such abrasive/binder each having an inner bottom edge defining an area devoid of coated abrasive, a top edge defining a somewhat larger area devoid of coated abrasive and an inner wall connecting the top and bottom edges.

摘要： This invention relates to the construction of backings for coated abrasive products that avoid curling tendencies during adhesive curing and subsequent steps. Curling of the backing is discouraged by the utilization of at least one finishing material carried by said fabric which comprises the product of a reaction between an unsaturated hexafunctional acrylated urethane oligomer component and an unsaturated carboxyfunctional monomer component. These components are caused to react with one another to form cross linking when exposed to actinic or electron beam radiation.

摘要： Coated abrasive material having a combination backing member. The combination backing member has as a bottom member a conventional backing member substrate used in the manufacture of coated abrasive material such as cylinder paper coated with a polymeric layer. The polymer layer provides a relatively smooth surface for application of the maker coat during manufacture of the coated abrasive material. The coated abrasive member can be used in diverse applications such as the fine finishing of particle board and offhand grinding of automobile body seams.

摘要： A new photopolymerizable composition which contains an addition polymerizable monomer, a photoinitiator, and an improved binding agent which is a polymer of three types of monomeric materials, namely, a styrene-type monomer, an acrylate monomer, and an alpha, beta-unsaturated carboxyl-containing monomer. These compositions are useful for flexible photopolymerizable films which, after exposure, may be developed in aqueous alkaline solutions. These films may be used as photo-resists, screen stencils and printing plates.
