Abstract
One-pot, dry erasable paints are provided. The dry erasable paints can be used to prepare dry erase coatings on virtually any type of substrate surface. The paints comprise a base component comprising monomers, oligomers, and/or polymers of a diisocyanate mixed with an admix component comprising a solvent. The paints are cured in a time of less than about 12 hours under ambient conditions, and once cured are markable-erasable with numerous writing and marking instruments, including temporary and permanent markers, paint, crayons, ink, and the like.
Claims13
A method of producing a dry erasable surface, said method comprising:
- providing a one-pot, dry erase paint comprising a base component and an admix component mixed with the base component, said base component comprising monomers, oligomers, and/or polymers of a diisocyanate, said admix component comprising a solvent, wherein said paint comprises a total solids content of greater than about 53% by weight and less than about 100% by weight;
- providing a substrate having a surface;
- forming a coating of said paint mixture adjacent said substrate surface;
- and
- allowing said coating to dry under ambient conditions and without the use of UV curing, wherein said coating has a surface, said coating surface being markable-erasable.
