Description
Two component epoxy primer for steel and concrete surfaces.
Scope and specifics of application
EPPEX F primer based on zinc phosphate pigments with high anti-corrosion efficiency is used as a primer or interlaminar coating in systems subjected to mechanical and / or chemical exposure. The primer is fast hardening at thermosetting and low temperatures. It is used to paint on assembly lines. It is convenient at production facilities where the technological process does not provide interoperation storage. It is suitable for industries where hot dryers are not available. It is used both for new metal structures anti-corrosion treatment and for repair work. Thick-layer application is possible in one pass. The material can also be used as a primer layer for concrete surfaces anticorrosive coating.
It is used as a primer or intermediate coating for epoxy and polyurethane based coating materials in complex protection systems as well as an independent coating inside premises or under a roof.
Due to its high chemical resistance, hardness and resistance to abrasive wear, the primer is good for anti-corrosion works at diverse industrial facilities. It is used to paint the internal surfaces of tanks for storing industrial water, dark petroleum products and mineral fertilizers as well as to protect steel surfaces, including bridges, vehicles, cranes, steel masts, conveyors and etc.
It can be used as an independent coating inside the room.
Information on the material resistance to various media is available on request.
Main fields of application: oil and gas industry, power engineering, mechanical engineering, transport construction.
Instruction for use
Metal surface should be abrasive blasted to grade 2 due to GOST 9.402 (Sa 2,5 or Sa 2 to ISO 8501-1:2007). Cleaned surface must be free of dust and grease.
If the quality of surface preparation decreases, the service life and its operating performance may change.
Conditions
Two component epoxy primer EPPEX F is applied on the surface at the air temperature from +50С to +350С and relative humidity no more 80%. It is possible to apply at a temperature of -50С, while the temperature of the primer should be at least 150С to ensure the necessary technological characteristics. Surface temperature should be 30 higher than dew point.
The process of applying
|
Blending |
The product is two component. Component А is a dispersion of pigments and anticorrosion filler in epoxy resin. Component B is a hardener solution. Mix the contents of the containers in the supplied proportions. After mixing, use within the specified pot life. Mixing sequence: The basis (component A) is mixed with a construction mixer. Then mixed hardener (component B) is added to the basis (component A) and thoroughly mixed with a construction mixer. Attention! Careless mixing or incorrect ratio can lead to uneven curing and painting film properties weakening. |
