NCA 2207

NCA 2207 is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for tile adhesives. It is based on a hard copolymer of vinylacetate and ethylene. It provides the basic properties adhesion and flexibility, giving a high degree of formulation freedom, offering you the best-in-class solution for a wide variety of applications.



Properties

  • NCA 2207 is a copolymer of vinyl acetate and ethylene that is dispersible in water.
  • Compounds modified with NCA 2207 exhibit improved adhesion and cohesion strength, flexural strength, abrasion resistance and workability.
  •  NCA 2207 contains fine mineral additives as anti-blocking agent. It is produced without adding organic solvents, plasticizers and film-forming agents.
  •  NCA 2207 has no effect on rheological properties. It is a hard dispersible polymer powder and suitable for formulating low emission tile adhesives of high cohesion and adhesion strength.

Processing

For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend NCA 2207 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.

If the product is used in applications other than those mentioned, the choice, processing and use of it is the sole responsibility of the purchaser. All legal and other regulations must be complied with.

Slight color variations of the polymer granulate may occure without impairing the product's functionality.

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.
