Abstract: A method for manufacturing a papermaker's or industrial fabric requires the application of a polymeric resin material onto preselected locations on a base substrate using an array which deposits the polymeric resin material in droplets having an average diameter of 10? (10 microns) or more. The preselected locations, for example, may be knuckles formed by the interweaving of the yarns making up the fabric or interstices between the yarns. The purpose of such precise application of the resin is to control functional properties of the fabric, such as permeability and abrasion resistance. The polymeric resin material is set by means appropriate to its composition, and, optionally, may be abraded to provide the polymeric resin material above the surface plane of the base substrate with a uniform thickness.

Abstract: The invention concerns the methods for producing polymeric coatings on particle surfaces and can be used in pharmacology, medicine, veterinary and cosmetology to create the systems of vector delivery of drugs and biologically active agents as well as in other fields applying the particles with thin-layer polymer coatings. The method enables to obtain biocompatible, particularly polyamide and polyimide coatings on inorganic particles including magnetic inorganic nanoparticles. The method for producing polymeric coatings on particles surface comprises (a) forming a reaction system containing the particles mixed with monomers, and (b) the subsequent carrying out of polymerization reaction to form the polymeric coating on the particles; wherein the said polymerization reaction is accomplished by irradiating the reaction system with electromagnetic radiation, particularly, with microwaves capable of being absorbed partially or totally by the said particles.

Abstract: The invention relates to a process for applying a liquid UV-curable primer sealant to natural stone tiles and related articles followed immediately by the exposure to a requisite amount of low intensity UVA-type UV radiation to partially cure the primer sealant. The partial curing, or pre-setting, of the primer sealant enables control of the ultimate depth of penetration of the primer sealer into the natural stone tiles and natural stone articles of which many examples are quite porous. Because the low level UV irradiation is instantaneous after the primer sealant application the level of primer sealant penetration into the natural stone surface is regulated. The pre-curing of the primer sealant is conducted to intentionally solidify or immobilize the sealant that has actually penetrated into the natural stone surface. The uppermost layers of the primer sealant are left in a semi-liquid or uncured state to allow for wetting and intermingling by the top sealant once it is applied.
