Application Advice/Typical Applications

PLEXTOL D 509 is preserved against bacterial and fungal attack. In the manufacture of finished products, the material has to be retreated, as usual, with suitable biocides to give enhanced preservation.

Above minimum film forming temperature PLEXTOL D 509 forms a clear, tack-free film. PLEXTOL D 509 is a pure acrylic dispersion, which is particularly stable against electrolytes and saponification resistant. The dispersion is especially used in hydraulically setting systems and has a liquefying effect, which renders a reduction of the water/cement ratio possible. By the addition of PLEXTOL D 509 plasticity and wet adhesion and consequently workability of mortars are improved. Following final properties of mortars are improved: flexural strength, adhesion, abrasion resistance, shrink/swell behaviour, water resistance, chemical resistance. Applications for PLEXTOL D 509 are: PCC-mortars in general, plasters for trowel applications, primers, sealers, floor screeds, self-levelling compounds, industrial floorings, and building adhesives. The addition of film forming aids is not necessary, when end products are applied in thick layers.

Shipping and Storage

PLEXTOL D 509 is supplied in road tankers or in non-returnable plastics drums secured by a lid with clamping ring or in non-returnable palletized bulk containers (net weight 1,000 kg). PLEXTOL D 509 has to be stored protected from frost and, as far as possible, below 40 °C. Storage at temperatures between + 5 and + 30 °C is recommendable. PLEXTOL D 509 contains a preservative to counter microbial attack during transportation. To protect it against germination during subsequent storage, absolutely stringent plant hygiene and, under certain circumstances, the addition of suitable preservatives will be necessary. Care must be taken to ensure that drums and storage containers are tightly closed. During processing, storage and transport of the product contact with metals unprotected against corrosion (likewise non-ferrous metals) has to be avoided. When stored correctly PLEXTOL D 509 has a storage life of 12 months from date of delivery.
