Improvement of storage stability and physicochemical properties by addition of benzoguanamine in melamine-formaldehyde resin synthesis

Abstract

The improvement of melamine-formaldehyde resin storage stability was achieved using benzoguanamine as partial replacement of melamine during synthesis (up to 15% substitution of melamine). The results showed that when benzoguanamine is added in the later stages of reaction, the resulting resins have improved storage stability (4 days or more, compared to 1 day in unmodified melamine-formaldehyde resin). High-pressure laminates produced with decor paper impregnated with the new developed resins showed surface properties equivalent to those obtained using commercial melamine-formaldehyde resins.
