This invention relates to polymeric compositions for application onto natural stone in order to provide for long-term chemical, stain, and water resistance, along with antimicrobial properties. Many natural, unsealed stones do not have stain, etch, or water resistance. The described compositions were developed using a technology of chemical grafting that involves the use of prepolymers, monomers, catalysts, graft initiators, wetting agents, antimicrobial agents, and other ingredients. The composition, when thus applied to the stone surface allows it to obtain a graft polymerization, thereby forming a polymer film that is chemically attached to the natural stone, rather than typical physical bonding of other sealer compositions. The natural stones react with a graft initiator in the composition, which creates the reaction sites on the natural stone surface. This in turn renders the natural stone to be receptive to attachment of monomers/prepolymers forming a polymeric film chemically bonded to the natural stone.

This in turn renders the natural stone to be receptive to attachment of monomers/prepolymers forming a polymeric film chemically bonded to the natural stone which then has the desired properties in terms of resistance to staining, etching, water penetration, etc., used in homes and light commercial applications, as well as for exterior use on building facades, monuments and the like.

Method for applying and curing by UV radiation a sealant system onto natural stone tiles to provide permanent sealing, protection, abrasion resistance, stain and mold resistance, and natural stone tiles produced by the method
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. Thus, the prior art problem of uncontrolled wicking is solved by the present invention.

A NEW METHOD FOR APPLYING AND CURING BY UV RADIATION A SEALANT SYSTEM ONTO NATURAL STONE TILES TO PROVIDE PERMANENT SEALING, PROTECTION, ABRASION RESISTANCE, STAIN AND MOLD RESISTANCE

The present invention relates to a method of sealing natural stone tiles and stone articles by applying and curing by UV radiation a liquid, solventless sealant onto natural stone tiles and articles to provide permanent protection, abrasion resistance, chemical and stain resistance and resistance to mold and other biological growth stains. The UV-curable solventless sealing composition comprises an effective amount of carboxyl functional, UV- curable reagent to provide for adhesion of the cured coating to the stone article. Additionally, the method describes the application of an optional liquid primer sealant comprising a UV- curable aqueous dispersion of an acrylate-functional resin.
Provided is a novel method for sealing natural stone. The method comprises applying a base coat comprising a synthetic polymer, drying the base coat, applying a UV-cure topcoat, volatizing organic solvents from the topcoat, and curing the UV- cure topcoat by exposure to UV light. The UV-cure topcoat used in the method comprises an acrylate oligomer, photoinitiators, and flow and wetting additives. Methods are also provided wherein the topcoat further comprises a fungal inhibitor. The described methods provide a coating with excellent adhesion, and a smoother, more uniform topcoat. Moreover, this coating system allows moisture to migrate from the back side of tile through the coatings to evaporate to the surface, a feature critical to preventing deterioration of the stone over time.
