| Processing
Polymist® XPP 541 is used as additives in paints and coatings where improvements in non-stick, mar resistance, slip, chemical resistance, and moisture repelling characteristics are desired.
Polymist® XPP 541 may be used independently as an additive or in combination with polyethylene waxes. The PTFE content at the surface layer is required in order to impart the properties of PTFE to the coating, substantially. Extreme environmental demands on greases, such as those experienced in the automotive industry (i.e. wide temperature ranges and heavy loads) can be accommodated by the addition of Polymist® XPP 541 micronized powders.
Polymist® XPP 541 can be dispersed easily at room temperature, and it doesn't agglomerate at temperatures used during formulation or printing. Chemical inertness and improved temperature resistance give ink formulators the opportunity to use a variety of solvents without adverse chemical reactions.
Storage and Handling
The usual precautions for safe storage and handling of Polymist® XPP 541 should be taken according to material safety documentation and experience. There will be no chemical deterioration of the Polymist® XPP 541 during proper storage.
Shelf life of Polymist® XPP 541 micronized powders will vary depending upon whether the recommended storage conditions are maintained and whether the material remains free from foreign contamination during storage time (not exposed to dirt, dust, water or other chemicals). The material should remain sealed in the original containers and storage conditions should provide for protection from temperature extremes as well as rain, snow or other wet environments (or such conditions which may damage the storage containers in which the product is stored).
Safety and Toxicology
Before using PTFE Polymist® XPP 541 micronized powders consult the product Material Safety Data Sheet and follow all label directions and handling precautions.
As with all PTFE materials, handling and processing should only be carried out in well ventilated areas. Vapor extractor units should be installed above processing equipment. Fumes must not be inhaled and eye and skin contact ought to be avoided. In case of skin contact wash with soap and water. In case of eye contact flush with water immediately and seek medical help. Do not smoke in areas contaminated with powder, vapor or fumes. See Material Safety Data Sheet for detailed advice on waste disposal methods.
Packaging
Polymist® XPP 541 is packaged in 25 kg non returnable drums. Each drum has one bag liner made of polyethylene resin. |
