VINNAPAS® 7031 H

VINNAPAS® 7031 H is a hydrophobic dispersible polymer powder for dry mix mortars, specifically suited for tile grouts, renders and plasters, wall and joint fillers. It is based on a flexible terpolymer of vinyl acetate, ethylene and vinyl ester. VINNAPAS® 7031 H belongs to the product class VINNAPAS® H which means that it provides a remarkable hydrophobic effect in addition to the basic properties workability and adhesion. 


Properties

  • VINNAPAS® 7031 H is a terpolymer powder of vinyl acetate, vinyl ester and ethylene and is dispersible in water.
  • Compounds modified with VINNAPAS® 7031 H exhibit improved adhesion, flexural strength, deformability, abrasion resistance and are easier to process.
  • Leveling, thixotropy and water retention are essentially unaffected. It additionally acts as a strong hydrophobizing agent, but will not have any appreciable effect on water-vapor transmission in normal usage concentrations.
  • As a result of the resin's special composition, compounds modified with it provide strong and lasting bulk water repellency on alkaline building materials and significantly reduced water absorption.
  • VINNAPAS® 7031 H contains a fine mineral filler as an antiblocking agent. It is produced without the use of organic solvents, plasticizers and film-forming agents.
  • VINNAPAS® 7031 H is a hydrophobizing dispersible polymer powder in the lower Tg range. It has no effect on rheology and has excellent general-purpose properties and is especially suitable for mortars with low emissions.

Processing

For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® 7031 H 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.

Packaging

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.
