POLYAMIDE POWDER WITH LONG-LASTING, CONSISTENTLY GOOD FLOWABILITY

Disclosed is a composition comprising from 88 to 99.99% by weight of a polymer selected from polyamides, derivatives of polyamides and mixtures of these, and from 0.01 to 0.25% by weight of a flow aid, where the drying loss from the flow aid after 5 days of conditioning at relative humidity of 95% i...

Beschreibung
Zusammenfassung:	Disclosed is a composition comprising from 88 to 99.99% by weight of a polymer selected from polyamides, derivatives of polyamides and mixtures of these, and from 0.01 to 0.25% by weight of a flow aid, where the drying loss from the flow aid after 5 days of conditioning at relative humidity of 95% is less than or equal to 1%, determined to ISO 787/2. The composition can be used for the coating of moldings, or the production of test specimens by laser-sintering process. The composition can also be used for a production of cosmetics or coating materials.
