VINNAPAS® 5343 E is typically blended with ASTM C 33 concrete sand or ASTM C 144 masonry sand and a small amount of Portland cement to produce high-performance polymeric joint sands.
Processing
For the production of polymeric joint sands blend VINNAPAS® 5343 E with the other dry ingredients in appropriate equipment. Temperatures should not be allowed to rise excessively during mixing because otherwise the dispersible polymer powder could agglomerate and lead to the formation of small lumps of resin. Base sand needs to be properly graded to avoid segregation during handling. In the field the paver sand is poured and swept into the joints. It is subsequently wetted down to start the film-forming process. Avoid sweeping the paver sand over more than a few feet and do not over-wet as polymer could be washed away before film has formed.

- Properties
- VINNAPAS® 5343 E is is a copolymer powder of vinyl acetate and ethylene.
- VINNAPAS® 5343 E contains a fine mineral filler as an antiblocking agent. It is produced without using film-forming or coalescing agents.
- VINNAPAS® 5343 E provides flexibility to paver sands to enable them to better withstand the effects of wetting & drying, ground movement, freeze-thaw & thermal cycling.
- It improves the resistance of paver sand to wash-off from rain, especially in high-exposure areas such as downspouts.
