Description
Two component epoxy primer for steel and concrete surfaces.
Scope and specifics of application
EPPEX SP is a two-component primer, anti-corrosion, fast-drying primer with high hardness and adhesion. The coating does not interfere with welding operations and is used as a shop primer in a layer of 15-25 microns, as well as a temporary protective primer. It can also be used as a primer coat in a layer of 40-60 microns in coating systems subsequently overcoated with Polytex products.
Instruction for use
Metal surface should be abrasive blasted to grade Sa 2,5 to GOST R ISO 8501-1-2014. 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 SP is applied on the surface at the air temperature from +50С to +350С and relative humidity no more 80%.
Surface temperature should be 30 higher than dew point.
The process of applying
|
Blending |
The product is two components. 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 |
