摘要:
An intumescent composition comprising the dried product of a composition containing as essential components (1) the reaction product of aluminum oxide or aluminum hydroxide hydrate and an organic amine phosphate or a salt thereof, and (2) expandable graphite flake.
摘要:
The preparation of phenol-formaldehyde and melamine-formaldehyde resin-based binders extended with a cyclic urea-formaldehyde prepolymer and to products prepared using the binders. More particularly, the invention relates to a cyclic urea prepolymer comprising urea, formaldehyde, and ammonia or a primary amine which, when added to a phenol-formaldehyde or melamine-formaldehyde based resin, results in a useful binder for the manufacturer numerous articles.

摘要:
Phenol formaldehyde resins that have low free formaldehyde when produced, that maintain their low free formaldehyde levels during storage, and that demonstrate low levels of formaldehyde emissions during processing, curing, and thereafter.
摘要:
Carbamate curing agents for phenol-aldehyde resins provide a delayed curing period for product assembly. Thereafter, the resin cures quickly even at low temperatures.
摘要:
A low molecular weight lignin fraction having a pre-selected molecular weight range prepared from lignin solution by ultrafiltration. The invention also relates to phenol-formaldehyde resin modified by the lignin fraction, adhesive comprising the modified resin, and a method for producing the lignin fraction and the resin.
