Abstract
A coating composition is stable upon long term storage and provides a highly durable coating on various substrates, such as wood. It can be a clear coating or a staining composition. The critical components of the composition are a self-curing vinyl polymer, a neutralized polyurethane, a water-soluble catalyst to promote rapid curing under ambient conditions, and an aldehyde, carbodiimide or polyfunctional aziridine which reduces discoloration of the composition upon storage.
