Description
Two component epoxy primer for steel and concrete surfaces.
Scope and specifics of application
EPPEX Cross primer based on zinc phosphate pigments with high anticorrosive efficiency is used as a primer or interlaminar coating in wet-on-wet systems (rapid overlap) with mechanical and / or chemical exposure. It can be used as an independent coating indoors. It is suitable both for new metal structures anticorrosive treatment and repair work. Thick-layer application is possible in one pass. The material can also be used as a primer layer for concrete surfaces anticorrosive coatings.
Best decorative effect of the coating in wet-on-wet systems is achieved with application of a wet film thickness up to 175 microns at viscosity of 18-25 seconds. Overlap with finishing materials should be carried out within 25-60 minutes at a temperature of 23-250C.
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 1 or 2 due to GOST 9.402 (Sa 2^(1/2) 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 CROSS 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.
Application
|
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. |
