VINNAPAS® 240 HD
VINNAPAS® 240 HD is a multi-purpose construction dispersion for liquid and paste, cement-free binder technology, specifically suited for primers, ready-to-use tile adhesives and one-component dispersion-based water-proofing membranes. It is based on a flexible copolymer of styrene and acrylate and belongs to the product class VINNAPAS® HD which means that it provides a remarkable hydrophobic effect in addition to the excellent adhesion even under wet conditions.
- VINNAPAS® 240 HD is a fine-particle 50% dispersion of a styrene/acrylic acid ester copolymer in water.
- Films based on VINNAPAS® 240 HD possess high water resistance and excellent adhesion even in wet conditions.
- VINNAPAS® 240 HD is also produced without the use of film-forming agents.
VINNAPAS® 240 HD is highly compatible with standard pigments and fillers. When using the dispersion in the preparation of filled, pasty compounds, it is advisable to raise its pH to a value > 7.5 prior to the addition of fillers. Since VINNAPAS® 240 HD contains no free ammonia, ammonia-free compounds can be prepared by adding KOH or 1)AMP-95®. Because of the low minimum film forming and glass transition temperature an addition of organic solvents or plasticizers is not necessary.
VINNAPAS® 240 HD is ideal for use in pasty construction and tile adhesives whose high adhesive strength is not affected by water or dampness. VINNAPAS® 240 HD can be used to produce construction adhesives and primers conforming to strict eco-labeling requirements.
