Title
(EN) MATTING AGENT BASED ON AGGREGATED SILICA
(FR) AGENT DE MATITE A BASE DE SILICE AGREGEE
Abstract
(EN)
The invention relates to an aggregated silica gel which has been produced from silica gel particles having a particle size of 1 to 20 $g(m), a surface of 200 to 1000 m2/g and a specific pore volume of 0.4 to 2.5 ml/g and a binding agent selected from synthetic or natural phyllosilicate, pyrogenic silicon dioxide and organic polymers soluble in water or dispersible in water. Aggregation takes place by spray-drying a suspension having 1 to 25 % solids. The product is suitable as a matting agent for coatings, as an antiblocking agent for polymer films and as a beer clarifying agent.
(FR)
L'invention concerne un gel de silice agrégée, produit à partir de particules de gel de silice présentant une dimension comprise entre 1 et 20$g(m), une surface de l'ordre de 200 à 1000 m?/g et un volume de pore spécifique se situant entre 0,4 et 2,5 ml/g, ainsi qu'un agent de fixation choisi parmi un phyllosilicate synthétique ou naturel, du dioxyde de silicium pyrogéné et des polymères organiques solubles dans l'eau ou se dispersant dans celle-ci. On effectue cette agrégation en séchant par pulvérisation une suspension comprenant 1 à 25 % de solides. Ce produit est approprié en tant qu'agent de matité destiné à des revêtements, en tant qu'agent antiadhérent destiné à des feuilles minces polymères, ainsi qu'en tant qu'agent de clarification de la bière.
