A glass board projection system includes a support board having a front surface with a defined area extending a length and a width; an anti-glare projector board composed of a glass material and that is removably secured to the support board, the projector board having a thickness extending from a front surface to a back surface; an attachment device rigidly attached to and protruding from the back surface of the anti-glare projector board and configured to removably attach to the front surface of the support board; and a gap formed between the support board and the anti-glare projector board, the gap being formed by the attachment device.

A garment having an outer surface not designed for writing has at least one rewritable area comprising a layer of rewritable material deposited directly onto a selected region of the outer surface. One or more permanent artworks may be deposited onto the garment prior to deposit of the rewritable layer, which may be contiguous or non-contiguous. A stencil is provided for allowing a user to write on rewritable areas while protecting adjacent areas of the garment. In one method for forming the rewritable area, a first portion of a permanent artwork and a second portion of the permanent artwork are successively deposited on the garment, followed by curing the permanent artwork and depositing a rewritable area on the garment.

An interactive high-clarity glass electronic whiteboard having a writing board body; the writing board body includes a base board and an ultra-thin tempered glass. The front of the base board attaches with the ultra-thin tempered glass. The attaching surface of the ultra-thin tempered glass attaching the base board is adhered with a non-transparent interlayer. A non-transparent coating is adhered to an attaching surface of the ultra-thin tempered glass attaching the base board A writing surface of the ultra-thin tempered glass is a matte surface with anti-glare treatment.

The present disclosure provides coating compositions free of acrylates and epoxies for use in dry-erase surface preparations and protective floor coverings.

Disclosed is a coating composition suitable for coating onto a wall or other substrate to yield a dry-erase coating. The composition may be prepared by reacting an excess amount of an aminosilane with a carbonate in aqueous media to yield a silylurethane, introducing an epoxysilane, and allowing the epoxysilane to react with the aminosilane to yield an aminodisilane. This reaction will result in a coating composition that comprises the silylurethane and the aminodisilane. The aqueous mixture of the silylurethane and the aminodisilane together constitute a coating composition that, upon curing, forms a dry-erase coating.

Disclosed is a coating composition suitable for coating onto a wall or other substrate to yield a dry-erase coating. The composition may be prepared by providing an aminoalkoxysilane, and in the substantial absence of water, reacting a portion of the aminoalkoxysilane with a carbonate and reacting a portion of the aminoalkoxysilane with an epoxy compound. These reactions will result in a coating composition that comprises a mixture of alkoxysilylamines and alkoxysilylcarbamates. The coating composition can also include an alkyl amine in an amount effective to catalytically deprotect alkoxy groups to yield silanol groups, facilitating fast crosslinking.

A dry erase writing surface has a low gloss level of 35-60 that can be utilized as both a writable/erasable dry erase surface and a projection surface, formed by a single component, 100% solids polyurethane, ambient cured, dry erase paint formulation. The paint formulation includes a low NCO isocyanate, a cure accelerating catalyst, a flow, leveling, and defoaming agent, a silica matting agent to reduce the gloss level of the applied coating, and an aliphatic hydrocarbon. The surface is ready for use in 24 hours. The coating has a low VOC of between 49 g/l and 99 g/1. The coating is applied to a prepared surface of a substrate to form a film thickness of 1-3 mils. Marks on the dry erase surface remain virtually invisible after 2500 cycles.

Disclosed is a dry-erasable coating composition comprising (a) a resin component comprising (i) an epoxy silane resin; and (ii) a cycloaliphatic epoxy resin different from the resin of (a)(i) and (b) an amino-functional crosslinking agent. A substrate at least partially coated with the dry-erasable coating composition and a method of making a dry-erasable surface are also described herein.

This disclosure relates to a method of presenting user interactive graphical content. More specifically, the disclosure relates to presentation of a writeable surface covering including a base layer displaying graphical content and a transparent layer applied to the base layer. Users may add user content to the writeable surface covering, such as, by writing or drawing on the covering using dry erase markers other suitable writing implements. The user content may overlay the graphical content without marring the graphical content, and the user content may later be erased from the writeable surface covering. The writeable surface covering may be adhered or otherwise attached to a wall or other support surface.
