Product is a completely soluble thermoplastic polyimide, containing no precursor - polyamic acid, and the polyamic acid
is converted into polyimide requires a high temperature condition of the job.Because of this, the polyimide products
more simple and convenient than conventional PI processing.For example, for coating applications, as long as the
product is dissolved in a solvent, coating on a substrate, and then to evaporate the solvent and form a dense, strong
toughness of the coating.For other types of polyimide, due to its solubility characteristics not only by its precursor -
polyamic acid to coat,However, this process requires a high temperature "curing" process, to be converted into a polyimide,
and the curing process will produce the byproduct water (polyamic acid is converted into polyimide is a chemical reaction
that produces water), Since water is generated, resulting in a smooth coating is difficult without "pinhole" or free of defects.
Soluble product which is completely cyclized polyimides, anhydrous generating process, can avoid this fatal defects.
Due to the special properties of soluble and very excellent temperature resistance (high glass transition temperature), and
has a very excellent beyond the conventional polyimide chemical corrosion resistance, such as: water, steam, salt, acid,
caustic and non-polar solvents (Note: Most of polyimide intolerance steam, acids and bases). Therefore, the product is
particularly suitable for high-temperature coatings and composites.
