摘要 |
<p>Low-viscosity high-solids-content melamine-formaldehyde condensates having high reactivity, low content of free formaldehyde and good compatibility, are prepared by effecting condensation in an alcohol having up to 3 carbons, then concentrating the condensate and heating the concentrate in a higher alcohol having from 3 to 18 carbons and again concentrating. The final product cures on heating to a hard glossy film and can be added to other uncured resins to improve the hardness of their films.</p> |
