Product Type: Acrylics & Acrylic Copolymers > Styrene / Acrylic Copolymers > Emulsions / Dispersions
Chemical Composition: Styrene acrylic copolymer
Orgal PR 667 is a styrene acrylic copolymer with very fine particles, developed as a primer for mineral substrates or formulations for impregnating wood stains.
Such low particle size emulsions are also referred to as "Hydrosols". Orgal PR 667 is a Hydrosol.
Orgal PR 667 is supplied as a low viscosity polymer with a bluish to clear appearance.
The polymer dries to give a slightly tacky, elastic and clear film.
Due to the very small particle size, Orgal PR 667 has excellent penetration and adhesion properties.

APPLICATION PROPERTIES
Orgal PR 667, having extremely small particle size, is especially suitable for the production of aqueous high penetration primers on substrates as plaster, concrete and asbestos cement.
The penetration power increases with decreasing solid contents.
However the reinforcing effect increases with the dry binder amount.
An optimum dilution should be decided by pretests.
Small quantities of surfactants would help the penetration power.
Orgal PR 667 is highly resistant to alkaline media thus making it compatible with gypsum and gypsum board.
Excellent penetration
Excellent adhesion
Excellent durability
PRODUCT HANDLING – STORAGE – SHELFLIFE
To ensure safe storage of this emulsion, containers should be well sealed to prevent the water evaporation and skin forming.
The emulsion must be stored between 5-25°C for a maximum of 12 months and freezing must be avoided.
Protect from freezing
