Imacoat HE-100 is a liquid organotin compound for the hot-end coating of glass containers and can be easily applied in suitable hot-end coating equipment. It can be processed without the use of dry compressed air by an airless feeding system and is not effected by temperature or humidity changes. Imacoat HE-100 forms under normal operating conditions tin oxide on the glass surface providing mechanical protection and the basis for the cold-end coating. The preferred surface temperature of the glass articles on which the coating is applied should be in between 450 °C and 600 °C.
