SMARGO® 328

SMARGO® 328  is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for ETICS. It is based on a semi-flexible copolymer of vinylacetate and ethylene and belongs to the product class SMARGO® which provides the basic properties adhesion and flexibility, giving a high degree of formulation freedom.

SMARGO® 328 is part of our standard range, offering you the best-in-class solution for a wide variety of applications.


Properties

  • SMARGO® 328 is comprised of a vinyl acetate-ethylene copolymer and is dispersible in water.
  • Mortar modified with SMARGO® 328 boasts superior adhesion, cohesion, flexural strength, abrasion resistance and workability.
  •  SMARGO® 328 contains small amounts of mineral additives as anticaking agents. No organic solvents, plasticizers, or film-forming additives are added during the production process.
  •  SMARGO® 328 is a general-purpose dispersible polymer powder with neutral rheological properties. With moderate flexibility, it is recommended for use in preparing end products with low emissions.
  •  SMARGO® 328 has good bond strength to both inorganic and organic substrates and is suited to prepare mortars with high cohesive strength and tensile adhesion strength.

For typical application fields of SMARGO® 328 , 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® 328 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.
