ORGAL PR 667

ORGAL PR 667

Orgal PR 667  is a low viscosity, styrene acrylic copolymer with very fine particles. Orgal PR 667 provides slightly tacky, elastic and clear films. Orgal PR 667 exhibits excellent penetration, durability and adhesion properties. Orgal PR 667 is suitable to produce aqueous high penetration primers and wood stains. Orgal PR 667 provides high resistance to alkaline media. Orgal PR 667 is compatible with gypsum and gypsum boards. The maximum shelf life is 12 months.

ORGAL PR 667 is a styrene-acrylic copolymer emulsion with very fine particle size.
Orgal PR 667, designed for both primers, can be included in the composition of wood paints.
ORGAL PR 667 - is supplied in the form of a low-viscosity emulsion with a bluish to white shade.
Orgal PR 667 provides a slightly sticky, elastic and transparent film.
Thanks to the very small particle size of Orgal PR 667s, the emulsion has excellent penetration and adhesion properties.

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 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 of Orgal PR 667

To ensure safe storage of Orgal PR 667, containers should be well sealed to prevent the water evaporation and skin forming.

Orgal PR 667 must be stored between 5-25°C for a maximum of 12
months and freezing must be avoided.
