Orgal PR 670
Orgal PR 670 is a non-plasticized styrene acrylic copolymer emulsion with very fine particles, developed as a primer for mineral substrates or formulations for impregnating wood stains.
Orgal PR 670 is supplied as a low viscosity emulsion.
The emulsion of Orgal PR 670 dries to give a slightly tacky and clear film.
Due to the very small particle size, Orgal PR 670 has excellent penetration and adhesion properties.

APPLICATION PROPERTIIES
Orgal PR 670, having extremely small particle size, is especially suitable for the production of aqueous high penetration primers on substrates as plaster, concrete and cement.
Small quantities of surfactants would help to increase the penetration power.
Orgal PR 670 is highly resistant to alkaline media thus making it compatible with gypsum and gypsum board.
Penetration power also depends on the porosity of the substrate.
Orgal PR 670 may also be used as a binder in impregnating wood stains
Penetrating stain varnishes
Wood primers
Penetrating primers
Concrete curing membranes
PRODUCT HANDLIING – STORAGE – SHELFLIIFE
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 6 months and freezing must be avoided.
Orgal PR 670 by Organik Kimya is a styrene acrylic copolymer.
Orgal PR 670 is recommended for architectural primers.
Orgal PR 670 is in-line with VOC regulations, phasing out formaldehyde, ammonia and other restricted substances.
