Beschreibung
Zusammenfassung:	The present invention is directed to the use of a polymer coating composition microbeads and a high Tg polymer with a Tg of greater than -10°C for the inner coating on natural and synthetic rubber articles, particularly for latex gloves. The coating composition provides an inner surface coating that reduces friction between the latex and the hand to allow convenient donning. The coating composition is deliverable from an aqueous solution. L'invention concerne l'utilisation d'une composition de revêtement polymère comprenant des microbilles et un polymère à Tg (température de transition vitreuse) élevée supérieure à -10 DEG C, destinée au revêtement intérieur sur des produits en caoutchouc naturel et synthétique, en particulier des gants en latex. Ladite composition de revêtement permet d'obtenir un revêtement de surface intérieure qui réduit le frottement entre le latex et la main pour permettre un enfilage fonctionnel. Cette composition de revêtement peut être distribuée à partir d'une composition aqueuse.
