ABSTRACT:
A process for manufacturing prefinished hardboard includes the use of a pre-press sealer comprising an aqueous mixture of a polyvinyl alcohol polymer in conjunction with emulsified fatty acid and/or fatty esters, an amine or similar emulsifier, and aluminum stearate. The pre-press sealer provides excellent sealing and hardening fiber binding to the porous fiberboard surface as well as improving the release from the press after the fiberboard is formed in a press under heat and pressure.
