Lithopol WR synthetic lightweight water resistant sprayable granules are available in two grades: Lithopol WR 500 (100-500 microns) and Lithopol WR 1000 (100-1000 microns).

The specific gravity of these granules is only 1,10 g/cc. These granules are based on an ISO polyester resin. They were developed especially for the production of fiber glass swimming pools (FGSP) in order to prevent the osmosis and bleaching effect, which is a very important factor for this application. Another reason why most of our FGSP customers use Lithopol WR granules is that they are lighter and more brilliant compared to the standard type of Lithopol granules and can cover much bigger surfaces per kg. However, some FGSP customers use Lithopol standard granules with a lower cost but without the above mentioned advantages.

Lithopol WR granules are available in several solid colors (white, black, blue, coffee, etc.) and also in ready mixed granite blends. The granite blends of Lithopol WR granules can also contain sparkling decorative granules (glitter) of different colors and sizes.
The Lithopol WR granules are applied by using a special type of transparent (clear) gel coat.

Packing: in 20 kg paper bags.
