Abstract
Se da a conocer una composición ligante para substratos tales como piezas de madera para la fabricación de planchas de partículas. El ligante comprende una mezcla de una primera solución acuosa, que comprende un catalizador de sal buffer y preferentemente una ácido con una segunda solución que comprende urea y fomaldehido. También se dan a conocer métodos para usar las sales buffer como catalizador para el curado de resinas de urea-formaldehido.A binder composition is disclosed for substrates such as pieces of wood for the manufacture of particle boards. The binder comprises a mixture of a first aqueous solution, which comprises a buffer salt catalyst and preferably an acid with a second solution comprising urea and fomaldehyde. Methods for using the buffer salts as a catalyst for curing urea-formaldehyde resins are also disclosed.
