Ammonium hydroxide scavenged binder for low TMA fiberglass insulation products |
摘要 |
A phenol-formaldehyde resole resin is combined with an ammonia-based formaldehyde scavenger to produce a product useful, for example, as a binder used in the production of glass fiber insulation products. The starting resin may have a free formaldehyde content of 1.5 to 14 wt. %, based on a total weight of the resin, and the resin and scavenger may be combined at a molar ratio in the range of 0.1 to 5. The resulting binder may have a free formaldehyde content of 1 wt. % or less, based on a total weight of the reaction product. This binder may then be applied to a glass fiber base material in a conventional manner.
