3.1 Standard environment

Standard environment is preferred, the provisions of the air temperature and humidity and atmospheric pressure and limit the speed range of constant air circulation

Environment, the air does not contain significant additional ingredient, and the environment is not any obvious external radiation affected.

[GB/T 2918-1998, Definition 2.1]

3.2 Test environment testatmosphere

Environmental constant throughout the test period in which the sample or specimen.

[GB/T 2918-1998, the definition 2.3]

3.3 Conditioning

One or more commands to the sample or specimen to reach equilibrium temperature and humidity conducted.

[GB/T 2918-1998, the definition 2.4]

3.4 Hard coat hardcoating

In the IMD level with a pre-coated film by wet coating process a thermal curing or UV curing hard coat layer formed on the film

Protective effects play a scratch resistant surface, there are two types of hard coat, one is a haze of 20% to 70% range of matte hard coat layer, and the second is

A haze of 1.5% or less of the transparent hard coat layer.

3.5 Precoated level primerside

The surface of the PET film, online or offline coating thickness of 0.1µm ~ 0.2µm polyester, polyurethane or acrylic

Pre-resin coating for improving adhesion fastness and the ink layer and the hard coat layer between the films.
