Enamel EP-255

Composition

The basis for enamel is epoxy resin E-41. EP-255 enamel is a two-component material, which consists of a semi-finished enamel and hardener No. 1. The semi-finished product and hardener are mixed immediately before use in a weight ratio of 100: 5. 

Categories: ,

The working condition of the prepared enamel EP 255 reaches 5 hours from the moment of mixing.

Purpose (EP-255)

The main purpose of EP 255 enamel is to paint various metallic and non-metallic surfaces. It has increased resistance to fresh water and its vapors, mineral oils and lubricants, gasoline, kerosene and other petroleum products.

Application

The surface must be dry and free from dust, dirt and other contaminants including peeling paint and corrosion. The material is stirred until uniform throughout the volume of the container. To dilute EP 255 Enamel, use solvent R-5A. Enamel is applied by pneumatic spraying, dipping or brushing. Consumption: – 60-80 g / m?) For one layer of white enamel; – 50-75 g / m? on one layer of green enamel. Work in personal protective equipment using a respirator and rubber gloves. Prevent material from entering the digestive and respiratory organs. To the workplace to ensure a constant flow of fresh air. It is forbidden to work near an open source of fire.
