Abstract: 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.

Abstract: A dry erase writing surface is formed from a single component, 100% solids polyurethane, ambient cured, dry erase paint composition having at least ninety percent by weight low NCO isocyanate, a cure accelerating catalyst and a defoaming agent. The surface is ready for use in a day. The composition can additionally contain a diluent, vegetable oil or mineral spirits. The coating has a VOC of between 0 and 49 g/l. The coating is initially applied to the surface of the substrate to form a film thickness of 1-3 mils. The whiteboard is characterized as when tested by erasure of the dry erase markers, the marks are virtually invisible after 2500 cycles. The composition can be packaged as a kit with applicators.
