Abstract:
A coating film is formed by the steps of supplying a mixture of a solvent for dissolving a coating liquid and a volatilization suppressing substance for suppressing the volatilization of the solvent onto the surface of the target substrate W, expanding the mixture onto the entire surface of the target substrate W, and supplying a coating liquid onto substantially the central portion of the target substrate W that has received the mixture while rotating the target substrate W thereby expanding the coating liquid outward in the radial direction of the target substrate W thereby forming a coating film.
Abstract:
A method using irradiation with optical light having a wavelength of 160 to 500 nanometers without higher wavelengths with cooling of the surface during the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light is filtered or the lamp (24, 106, 212, 306, 510) is restricted to the limited range to avoid the affects of the higher spectra. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 306, 410, 508) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.

Abstract:
The present invention relates to improving the durability of water repellent films and a method for providing the film on a substrate. The water repellent film is preferably formed over the substrate by applying a water repellent composition over the substrate which will form the water repellent film. The durability of the water repellency of the film is improved by activating the substrate with an acid prior to forming the water repellent film over the substrate.
Abstract:
Discoloration of surfaces, such as painted or treated wood surfaces, by tannin-staining caused by the complexing of certain transition metal ions with tannate ions (the process is often referred to in the art as "tannin-stain bleed") is reduced or prevented by contacting a transition metal ion on a painted surface or surface to be painted with a complexing agent for the transition metal ion, such as by the addition of the complexing agent for the transition-metal ion to paint formulations or by pretreatment of the wood surface with the complexing agent before painting. It is believed that the complexing agents form coordination complexes with transition-metal ions on the surface of and within the paint film, thus preventing the formation of highly-colored complexes of the transition metal ions with the tannate ions derived from the tannins in the wood. This technique is applicable to all woods and other surfaces susceptible to tannin-staining and especially to stain-susceptible woods such as redwood and cedar. Using appropriate formulation or application techniques, the method may be used with water-based or solvent-based paints.
Abstract:
This invention relates to curing of coatings, sealants and laminates under ambient conditions without affecting the pot life of a curable liquid composition comprising a polyene containing at least two reactive unsaturated carbon to carbon bonds per molecule and a polythiol containing at least two thiol groups per molecule, the total combined functionality of (a) the reactive unsaturated carbon to carbon bonds per molecule in the polyene and (b) the thiol groups per molecule in the polythiol being greater than four which comprises having present at least a minor amount of an iron-containing material either as a portion of the substrate, as a primer coat for the substrate or as a top coat for the curable composition. In the case where oxygen is excluded from the reaction, a minor amount of an oxime ester is added to the system to assure curing to a solidified product.
Abstract:
A silicone rubber coated substrate and method for preparing the same which comprises treating a substrate with a primer solution containing an omega -amino-organosilane and thereafter coating the primed substrate with a room-temperature-curable organopolysiloxane composition containing a silane compound having both an oxirane ring and a hydrolyzable group on the silane molecule. The silane compound will react with the primer composition and also act as a curing agent for the organopolysiloxane composition to provide an adhesive bond between the silicone rubber and the substrate.
Abstract:
Systems and methods relate to applying a coating to a substrate. Coatings can be generated using layer-by-layer application techniques. Typically, application of a first aqueous solution is alternated with application of a second aqueous solution. Example first aqueous solutions include polyethyleneimine (PEI) and hydroxy-terminated poly(dimethylsiloxane) (PDMS-OH). Example second aqueous solutions include silicate and PDMS-OH. In some instances, first aqueous solutions and/or second aqueous solutions additionally include methyl-terminated PDMS (PDMS-CH3).
Abstract:
A multilayer vehicle exterior coating is both durable and easy to install and conforms FAA standards. This vehicle sheet coating has no film or substrate resulting in a finished coating sheet that is about 6 mils thick (0.006″). The multilayer protective sheet material is suitable for application to vehicle exterior surface.
