Product Description

 

3M™ Dyneon™ PFA 6900GZ is a 50% solids fluorothermoplastic aqueous dispersion. It is a melt-processable copolymer of tetrafluoroethylene and perfluorinated comonomers, with a melt viscosity several orders of magnitude lower than PTFE.

 

It can be utilized in coating system formulations and in combination with conventional PTFE dispersions, binding resins, and pigments. Dyneon PFA 6900GZ is ideal for use as a protective fabric coating and, particularly in combination with PTFE dispersions, for coating and impregnating glass fiber fabrics and metal and ceramic substrates.

 

Processing

 

PFA 6900GZ is applied by dipping, impregnating or spraying. Melting of the polymer particles and film formation normally occurs between 320°C and 380°C (608°F and 716°F). To avoid blistering, we recommend drying the applied coating at a maximum of 90°C (194°F).

 

This dispersion can be processed in concentrated or diluted form, utilizing either distilled or demineralized water.

 

Product Form

 

PFA 6900GZ is furnished in 40 kg (88 lb) drums.

 

 

Storage and Material Handling

 

This aqueous dispersion must be protected from freezing. It should be stored at temperatures between 5°C and 15°C (41°F and 59°F). Although it has a minimal tendency to settle, it is recommended that PFA 6900GZ dispersion be homogenized by gently drum rolling at low rpm

 

(2-4) for 10-15 minutes once every 2 months. Before use, the dispersion must be rolled and filtered with a 100-micrometer filter.

 

Safety/Toxicology

 

This product is a fluoroplastic material, so normal precautions observed with fluoroplastics should be followed. Before processing this product, be sure to read and follow all precautions and directions for use contained in the product label and the Material Safety Data Sheet. General handling/processing precautions include: (1) Process only in well-ventilated areas; (2) Do not smoke in areas contaminated with powder/residue

 

from this product;(3) Avoid eye contact; (4) After handling this product wash any contacted skin with soap and water. Potential hazards, including evolution of toxic vapors, can exist if processing occurs under excessively high temperature conditions. Appropriate local exhaust ventilation such as vapor extractor units should be installed above processing equipment. When cleaning processing equipment, do not burn off any of this product with an open flame or in a furnace.
