<p>Coating compositions comprising an alkylated ureaformaldehyde resin, a polymethylolcyclohexane and a polyoxypropylene polyol which are useful for low temperature cure and are low in viscosity to allow ease of coating without the need for appreciable amounts of solvent thinners. The alkylated urea-formaldehyde condensates have an average degree of condensation of about 3 or less and a combined urea:formaldehyde: alcohol ratio in the range of about 1:2-3:1-2.5. The compositions may be cured in the presence of acid catalysts in the temperature range of 70 to 105.degree.C., and are particularly useful for coating paper, cloth and wood substrates.</p> |
