Application
DEXICRYL 16V03 is used to manufacturer building adhesives such as tile adhesives in paste form and panel adhesives, etc. The high binding power of DEXICRYL 16V03 also allow it to be used to formulate primers, textured finishes and sealants.
   
 
Formulations that contain pigments and fillers have to contain dispersing agents in sufficient quantities to ensure that they remain stable in storage.
   
 
The minimum film-forming temperature of DEXICRYL 16V03 can be lowered by adding a coalescent solvent in the required quantity. Cellulose ethers and polyacrylates can be used to adjust the viscosity.
   
 
Commercial defoamers can be used to suppress foam. It is usually sufficient to ass 0.05 – 0.2%, expressed as a proportion of the adhesive. The exact amount of defoamer has to determine in trials.
   
 
We would recommend adding preservatives to adhesives and sealants that contain DEXICRYL 16V03 to protect them from microbial attack over long periods in storage. The compatibility and efficacy of preservatives must be tested in trials.
   
Safety General
The usual safety precautions when handling chemicals must be observed. In particular, the place of work must be well ventilated if large quantities are processed, the skin should be protected, and safety glasses should be worn at all times.
 
Safety Data Sheet
A safety Data Sheet is available for DEXICRYL 16V03 which contains up-to-date information on all questions relevant to safety.
 
Labelling
According to all the data at our disposal, DEXICRYL 16V03 does not need to be labelled as a dangerous substance or preparation as defined in the relevant European Union directives according to their current status.
 
Storage
DEXICRYL 16V03 has a shelf life of six months at 10-300 C in tightly sealed containers. Like other polymer dispersions, DEXICRYL 16V03 is sensitive to iron, copper, zinc and aluminium. It must not be allowed to come into contact with these metals or their alloys in storage or in pipeline, mixers and other industrial equipment.
We would recommend treating this product with a biocide in order to prevent problems with microorganisms from occurring during storage and processing. Further details are given in our leaflet on “The handling and storage of polymer dispersions”
