Изобретение относитс  к области литейного производства.The invention relates to the field of foundry.

Известно применение в качестве полупосто нных разделительных покрытий модельной оснастки дл  устранени  прилипаемости жидких самотвердеющих смесей большой группы химически стойких лаков и эмалей, в частности эпоксидной.It is known to use model equipment as semi-permanent release coatings to eliminate the adhesion of liquid self-hardening mixtures of a large group of chemically resistant varnishes and enamels, in particular epoxy.

Цель изобретени  - повышение стойкости покрыти  и его адгезионных свойств.The purpose of the invention is to increase the durability of the coating and its adhesive properties.

Дл  этого в состав покрыти , включаюш,его эпоксидную эмаль, дополнительно ввод т низкомолекул рный кремнийорганический каучук при следующем соотношении компонентов, %: Эпоксидна  эмальосноваFor this purpose, the coating, including its epoxy enamel, is additionally introduced with low molecular weight silicone rubber in the following ratio of components,%: Epoxy enamel

Совмеш,а сь с основой, кремнийорганический каучук способствует образованию на поверхности модельной оснастки молекул рного резиноподобного сло , обеспечивающего ликвидацию прилипаемости жидкой самотвердеющей смеси к модельной оснастке. П ри м ер. Состав, покрыти ,, вес. %: Эпоксидна  эмаль ОЭП417195-99Combined with the substrate, silicone rubber promotes the formation of a molecular rubber-like layer on the surface of the model tooling, which eliminates the adhesion of the liquid self-hardening mixture to the model tooling. For example. Composition, coating ,, weight. %: Epoxy enamel OEP417195-99

(предпочтительно )(preferred)

Применение кремнийорганического каучука в большем количестве приводит к «высаливанию его на поверхности покрыти  и нарушению его сплошности.The use of silicone rubber in larger quantities leads to "salting it out on the surface of the coating and disrupting its continuity.

В качестве основы покрыти  может быть использована и друга  основа, например полиуретановый лак; при этом необходимым условием  вл етс  совмещение основы с кремнийорганическим каучуком.As the basis of the coating, another base may be used, for example a polyurethane varnish; however, a prerequisite is a combination of the base with silicone rubber.
