Polyimide chemistry

P84® Coatings – Beyond the limits of polymer coatings

Polyimide P84® imparts excellent heat resistance to high performance coatings.

P84® Solution for PI coatings

Polyimides from Evonik are well known for their remarkable heat stability and creep resistance, even at elevated temperatures of 250°C or higher, so they are the right choice for coating applications in challenging environments.

Since P84® is soluble in a range of selected solvents, there is no curing step necessary, reducing complexity during the coating process.

Heat resistance

No melting point and a glass transition temperature of 315℃ ensure exceptional thermal stability.

Product Range

Polyimide P84® is provided as polymer solution with up to 25% solid content in a variety of solvents including DMF (Dimethylformamide), NMP (N-Methylpyrrolidone), NEP (N-Ethylpyrrolidone).

Low tox solvent mixtures based on DMSO (Dimethylsulfoxide) are also available.

Preferred processing

Application processes for P84® polyimide solutions include, among others, casting (doctor blade), dipping, spin-coating, spraying or roller-coating.
