摘要:
The present invention provides coatings that provide improved repellency for certain foreign substances, such as low viscosity liquid stainants, and reduced adhesion against other foreign materials, such as high viscosity liquids and slurries. In one embodiment, the present invention provides a coated flooring substrate, comprising a flooring substrate and a coating on the flooring substrate, wherein the coating comprises a cured resin and a low surface energy additive having a fluorocarbon or silicone functional group, in which the cured resin and the low surface energy additive each comprise a cured form of a substantially similar reactive group. The present invention also provides coating mixtures from which any of the coatings of the present invention may be made. The present invention also provides methods for making coating flooring substrates, including sheet flooring and floor tiles, having coatings made according to the present invention.
摘要:
In one embodiment the present invention provides a coated substrate comprising a substrate, a radiation-cured coating or a thermally-cured on at least a portion of the substrate, wherein the coating comprises an inherent macroscopic texture. In another embodiment, the present invention provides a pre-cured coating mixture comprising a radiation-curable resin and an initiator, or a thermally-curable resin and thermal initiator, wherein the radiation- or thermally-curable resin and the respective initiator form a pre-cured coating mixture capable of forming a macroscopic texture upon application of the mixture on a substrate. In another embodiment the present invention provides a pre-cured coating mixture comprising a radiation- or thermally-curable resin, an initiator, and texture-producing particles having an effective size to provide a macroscopic texture upon application of the mixture on a substrate. In another embodiment, the present invention provides a coated substrate comprising a substrate and a radiation- or thermally-cured coating on at least a portion of the substrate, wherein the coating comprises an inherent macroscopic texture. In addition, the present invention provides a process for making a coating on a substrate, comprising the steps of distributing a pre-cured coating mixture comprising a radiation-curable resin and an initiator or a thermally-curable resin and thermal initiator over at least a portion of a substrate to form a pre-cured coating having a macroscopic texture, and radiation-curing or thermally curing, respectively, the pre-cured coating to form a radiation-cured or thermally-cured coating having the macroscopic texture.
摘要:
A composition comprising (a) a resin composition comprising a block copolymer of the formula hydrocarbon-polyether-polyamide-polyether-hydrocarbon; and (b) a polar liquid. The block copolymer may be prepared by a process comprising reacting together reactants comprising dimer acid, diamine, and a polyether having termination at one end selected from amine, hydroxyl and carboxyl, and termination at another end selected from hydrocarbons. The polar liquid may be one or more of an aromatic liquid, a polar aprotic liquid, a ketone-containing liquid, an ester-containing liquid, an ether-containing liquid, an amide-containing liquid and a sulfoxide-containing liquid. The composition may be a gel at room temperature.
