摘要： The invention relates to crosslinkable or crosslinked silicone compositions capable of being used to form a water-repellent and release coating for a flexible support made of paper or of polymer, in particular that is heat-sensitive. These compositions are of the type of those comprising crosslinking polyorganosiloxanes (POSs) bearing =Si-H units and unsaturated, preferably =Si-Vi, vinyl-containing POSs, capable of reacting with the crosslinker by polyaddition, in the presence of platinum in order to form the crosslinked release coating on the flexible support. The targeted objective is to enable the coating composition to crosslink instantaneously in order to produce, on all types of flexible supports (paper, e.g. glassine, or polymer, e.g. polyester such as polyethylene terephthalate PET), a crosslinked silicone coating endowed, in particular, on leaving the coating machine, with excellent attachment (adhesion) and mechanical strength or cohesion - "Rub-off" - properties. In order to achieve this objective, the invention proposes the use, per 100 parts by weight of silicone base, of 1 to 40 parts by weight of an additive comprising from 1 or 5 to 80% by weight of particulate filler, preferably nanoscale filler, in a silicone oil capable of reacting with the crosslinker. The supports and the high-speed coating processes are targeted. Applications: silicone release coatings obtained by crosslinking/polyaddition for flexible supports.
摘要翻译：本发明涉及可交联或交联的硅氧烷组合物，其能够用于形成由纸或聚合物制成的柔性载体的防水和释放涂层，特别是对热敏感的。这些组合物属于包含交联聚有机硅氧烷（POS），其中含有= Si-H单元和不饱和的，优选= Si-Vi的含乙烯基的POS的那些类型，其能够在铂的存在下依次通过加聚反应与交联剂反应以在柔性载体上形成交联的释放涂层。目标是使涂料组合物瞬时交联以在所有类型的柔性载体（纸，例如玻璃纸，或聚合物，例如聚酯如聚对苯二甲酸乙二醇酯PET）上产生交联硅氧烷涂层，特别是，在离开涂布机时，具有优异的附着力（附着力）和机械强度或内聚力 - “擦除”性能。为了实现该目的，本发明提出每100重量份硅酮基使用1至40重量份的添加剂，所述添加剂包含1或5至80重量％的粒状填料，优选纳米级填料，在能够与交联剂反应的硅油中。支架和高速涂层工艺是针对性的。应用：通过交联/加聚获得用于柔性载体的有机硅防粘涂料。
