Orgal PR 845 A

Orgal® PR 845 A is an APEO and zinc oxide free, acrylic polymer emulsion developed for the formulation of very high quality stain-blocking primers for wood, walls, ceilings, and metal surfaces. It is possible to formulate low VOC products according to EU Directive 2004/42/CE, since the polymer has good low temperature coalescence performance.

Orgal PR 845 A is suitable for:

• Interior tannin/stain blocking primers
• Wood primers
• Primer undercoats
• Primers with flash and early rusting resistance on metal surfaces

Orgal PR 845 A can be used in formulations without additional zinc oxide as a stain-blocking agent; however, if zinc oxide is used in the formulation, it is compatible with the zinc oxide.

Key Features

• Excellent stain-blocking property
• Excellent adhesion on wood
• Resistance to flash rusting
• Compatible with zinc oxide and a variety of fillers and pigments

To ensure safe storage of this emulsion, containers should be well sealed to prevent 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.
