  • Patent number: 5637374
    Abstract: The invention relates to the use of a resorcinol-glutaraldehyde reaction product as an accelerator for thermosetting phenolic resin and to a method of making the accelerator. Further, the invention relates to a resin blend comprising phenol-formaldehyde and the accelerator and a process for making cellulosic board, oriented strandboard and plywood wherein the binder for the cellulosic board, oriented strandboard and plywood in its uncured form comprises the resin blend of the invention. In another embodiment the accelerator for thermosetting resin comprises resorcinol and glutaraldehyde.

  • Patent number: 4536245
    Abstract: A melamine-urea-formaldehyde resin characterized by a low rate of formaldehyde emission when cured. Made by a process where the initial reaction mixture has an F/U molar ratio of from about 3:1 to about 1:1, and undergoes a methylolation reaction at an alkaline pH. Preferably at least some of the melamine is present in the initial reaction mixture. The subsequent condensation is at a substantially neutral pH. Has a final F/U molar ratio of 1.3:1 to 0.9:1, a final F/Ueq molar ratio of 1.3:1 to 0.7:1, and a melamine content of from 0.15% to 40% by weight, dry solids basis. Useful for adhesive purposes, particularly as a particleboard binder characterized by low emission rate.
