Abstract:
Spherical particles with a mean diameter in the range 1 to 20 μm, containing: a) 85 to 99 wt. % of a cross-linked statistical copolymer with a glass temperature T9 in the range -75 to -40°C and b) 1 to 15 wt. % of at least one organic substance, selected from waxes, protective colloids and plasticisers.
Abstract:
The invention relates to the spray condensation method for the production of dried resin in powder form made from melamine, urea or mixtures thereof and at least one aldehyde, whereby the morphology of the produced resin particles may be specifically influenced with regard to the particle parameters thereof.
