>    1. Paste performance test: easy to paste on the surface, without leaving adhesive residue: a 90 degrees bending over objects, not broken, do not fall off; after tear off of the paint film Zi Baosuo test, not in the surface film residue.
    2. Load test load withstand / SPCM2: 360h25 degrees -50 degrees, peeled rubber track residual surface.
    3. UV resistance test: 50 degrees 300w UV lamp 60h after irradiation does not crack, no deformation, tear off the rear surface residual traces.
    4. Resistance to heat aging test: 60 degrees +80% = 240H does not fall off, peeled off without leaving adhesive residue, non-corrosive surface.
. Paste requirements: to be affixed to the surface to be dust-free and free of grease.
