CNP 44 is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for ETICS, waterproofing membranes and concrete repair mortar. It is based on a very flexible copolymer of vinylacetate and ethylene which has a neutral effect on rheology and 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.
- CNP 44 is a copolymer powder of vinyl acetate and ethylene and is dispersible in water.
- Because of its relatively high ethylene content, this resin is soft and flexible, its glass transition temperature (Tg) is below the freezing point of water.
- Compounds modified with CNP 44 exhibit improved adhesion, flexural strength, deformability, abrasion resistance and are easier to process. Leveling, thixotropy and water retention are essentially unaffected. The product is ideal for use in combination with other mortar additives intended to enhance specific properties.
- CNP 44 contains a fine mineral filler as an anti-blocking agent. It is produced without the addition of organic solvents, plasticizers and film-forming agents.
- CNP 44 has no effect on rheological properties and is a general-purpose powder in the lower Tg range. It is suitable for formulating highly flexible compounds with very good adhesion to organic substrates (polystyrene) and end products with low emissions
For typical application fields of CNP 44 , refer to the section "application". Please discuss additional applications with your WACKER customer representative.
For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend CNP 44 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.
