Novolak molding compounds containing hexamethylenetetramine
monometaborate
摘要:
Manufacture of rapidly hardening phenol formaldehyde resin molding compositions having improved thermal stability and good flow characteristics by incorporating into the molding compositions hexamethylenetetramine in the form of a metaboric acid addition product. The resulting molding composition is then rolled and ground to produce the molding composition of improved properties.
