Properties
Two-component Enamel AC 1115 is a system that consists of a semi-finished enamel and hardener. Before the application process, they are mixed. Prefabricated enamel is a suspension of pigments in solutions of acrylic resin C-38 and epoxy resin with the introduction of a plasticizer. The hardener is a 20% solution of orthophosphoric acid in butanol. Prefabricated enamel and hardener are supplied.
Purpose (AC-1115)
Due to its characteristics. Enamel AC 1115 has found wide application in aircraft manufacturing and aircraft repair. It is used in the dyeing of metal products and light alloys, which are operated in extreme atmospheric conditions and can withstand temperature drops from -60 to 150 ° C.
Application
The process of making enamel occurs immediately before use. Hardener, 1.2 parts of hardener are added to the semi-finished product, 2.2 parts of the hardener are added to 100% of the semi-finished product other colors. Apply the enamel AC 1115 on the surface should be sprayed. If necessary, gray enamel is diluted with solvent R-5A. The surface must be dry and free from dirt and dust. Work in personal protective equipment using a rubber gloves. To the workplace to ensure a constant flow of fresh air. Do not carry out work.
