UNIFINER

Processing Characteristics of UNIFINER

1. Film

In view of the excellent solubility to solvents, the cast method is recommended when making UNIFINER into film.
Making UNIFINER into film by the melting extrusion method needs processing in a very high temperature range, because the glass transition temperature of UNIFINER is high. Therefore, pay special attention to the selection of a processing machine, as well as to the thermal decomposition and hydrolysis of resin.

2. Coating

UNIFINER can dissolve in solvents with a low boiling temperature. It has excellent processability and permits easy removal of solvents as a coating material, reducing generation of outgas from products.
The formed film has excellent toughness and resistance to hardness and abrasion.
Utilization of such properties permits surface reforming (improvement of heat resistance, hardness, and wear resistance) of plastic film (sheet).
In comparison with other kinds of transparent resin, UNIFINER has excellent adherence, and its use as a protective coating for metal is expected.
