    Abstract: Moulding compositions comprising(a) a melamine/formaldehyde resin, a melamine/phenol/formaldehyde resin or a mixture of said resins,(b) organic and/or inorganic fillters,(c) a lubricant, and(d) 0.1 to 2% by weight, based on on the total composition, of 3-chloro-1,2-propanediol as latent hardener,are suitable for the production of mouldings by injection moulding. The latent hardener employed permits extremely short cycle times coupled with long residence times at the cylinder temperature of the injection moulding machine. The moulding compositions are distinguished at the same time by very good flow properties.
