Abstract

A reaction catalyst for the polycondensation of amino resins used for bonding water-penetrable cellulosic particles is disclosed. Said catalyst, if used in combination with a known catalyst, increases the rate of polycondensation of the resin while at the same time allowing the use of lower amounts of resin solids without imparting any loss in bonding strength. The catalyst comprises a concentrated aqueous solution of a mixture of organic and inorganic components, the organic components being formaldehyde and urea or a non resinous condensation product of formaldehyde and urea, and the inorganic component being a water-soluable alkali metal halide.
