Title
(EN) SOLID SILOXANE POLYMERS AS DELIVERY AGENTS FOR SILOXANE TACKIFYING RESINS
(FR) POLYMÈRES SOLIDES DE SILOXANE EN TANT QU'AGENTS DE DISTRIBUTION POUR DES RÉSINES COLLANTES DE SILOXANE
Abstract
(EN)
Blend compositions include at least one polydiorganosiloxane polyoxamide copolymer, and at least 70% by weight of at least one silicone tackifying resin. The blend composition is non-tacky at room temperature up to a temperature of at least 100°C. The polydiorganosiloxane polyoxamide copolymer can be a linear or branched copolymer. The blend compositions provide solid, non-powdery, and non-tacky delivery vehicles for silicone tackifying resin.
(FR)
Les compositions de mélange comprennent au moins un copolymère de polydiorganosiloxane-polyoxamide et au moins 70 % en poids d'au moins une résine collante de silicone. La composition de mélange est non collante à température ambiante jusqu'à une température d'au moins 100°C. Le copolymère de polydiorganosiloxane-polyoxamide peut être un copolymère linéaire ou ramifié. Les compositions de mélange permettent d'obtenir des véhicules de distribution solides, non poudreux et non collants pour une résine collante de silicone.
