Thermal curing optical film
In-page Navigation

What is thermal curing optical film?
It is thermal curing optical film that offers superior heat and weather resistance.
We are developing and proposing the HR series transparent type and the WR series white type.
Have you experienced these issues?
I would like to bond the materials by the simple lamination process.
case
01
The film is required the heat resistance.
case
02
The optical stability of the film is the important point.
case
03
Here is the product that resolves these issues.
