SMARGO® 309

SMARGO® 309 is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for thermal insulation integrated board system. It is based on a hard copolymer of vinylacetate and ethylene and belongs to the product class SMARGO® which means that it has a neutral effect on rheology and provides the basic properties adhesion and flexibility, giving a high degree of formulation freedom. SMARGO® 309 is part of our standard range, offering you the best-in-class solution for a wide variety of applications.


Properties

  • SMARGO® 309 is a copolymer of vinyl acetate and ethylene that can be dispersed in water by mixing.
  • Compounds modified with  SMARGO® 309 exhibit improved adhesion and cohesion strength, flexural strength, flexibility, and workability and low VOC.
  • SMARGO® 309 contains fine mineral additives as anti-blocking agent. It is produced without adding organic solvents, plasticizers and film-forming agents.
  • SMARGO® 309 is rheology neural while exhibited good workability in applications. It is a relative hard polymer and suitable for formulating very low emission dry-mix applications.

For typical application fields of  SMARGO® 309, refer to the section "application". Please discuss additional applications with your WACKER customer representative.

Processing 

For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend  SMARGO® 309 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 by virtue of its thermoplastic properties. The mortar is prepared for use by adding the recommended amount of water and mixing mechanically or by hand. Since hand mixing generates little shear force, we recommend allowing the fresh mortar to slake for 5 minutes and then stirring it again. This is usually unnecessary where mechanical mixers are employed.

Storage

During storage, protect the product from contact with moisture. Prolonged storage at temperatures above 30 °C, especially in combination with pressure, humidity or exposure to sunlight, may result in blocking. Carefully seal any open containers and store them under suitable conditions. We recommend storing the product in a warehouse that provides cool and dry conditions. Do not store the product for more than six months, starting from the date at which it was received, unless the Certificate of Analysis contains a different date, which would take precedence. If the product is stored longer than recommended, it may still be used but users are advised to verify the properties required for the intended use.
