Description
Two component thickfilm epoxy primer with high dry residue and good abrasion resistance. Can be applied in thick layer.Scope and specifics of application
EPPEX MASTIC primer is a highly structured, thick-layer coating with a high dry residue and fast open time to protect steel surfaces. The coating is resistant to a wide range of chemicals, oils, gasoline, salt solutions, acids, and alkalis impacts. It is resistant to sea, fresh and polluted water, high humidity, medium and highly aggressive industrial atmosphere.
It is intended for anticorrosive protection of new and repairable metal structures. 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 used inside premises or under a roof.
It is used to paint horizontal and vertical surfaces of alluvial and tank equipment of mineral oil, salt solutions, alkalis, oil refining products storage tanks, tanks, storage facilities as well as pipes and pipelines, oil and gas pipelines. it is used to paint metal structures, structures and equipment exposed to aggressive gases and vapors at enterprises producing mineral fertilizers, chemical, oil refining and other industries.
Information on the material resistance to various media is available on request.
Main fields of application: chemical industry, oil and gas industry, power engineering..Instruction for use
Metal surface should be abrasive blasted to grade 1 or 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.Conditions
Relative air humidity no more 80%.
To provide curing in closed space good ventilation is needed.
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. |
