CURABLE COMPOSITION COMPRISING AN ALKALINE PHENOLIC RESOLE HAVING DISPERSED THEREIN MELAMINE CRYSTAL AND AN ACID TO CATALYSE THE REACTION BETWEEN THE MELAMINE AND THE RESOLE RESIN AND LOWER THE PH OF THE COMPOSITION |
摘要 |
<p>The invention relates to a composition consisting of a melamine solid suspended or dispersed in a resole resin. The method of the invention favors the intermolecular condensation polymerization reaction between phenol and melamine, rather than homopolymerization between phenol molecules or between melamine molecules. This invention reduces formaldehyde emissions by favoring a reaction whose by-product is water rather than formaldehyde. The compositions are useful for bonding glass fiber mats used for thermal and acoustical insulation.</p> |
