Model number

JIAZHI®JZ-9570-10

Specification

Note: This data sheet is intended to give typical results, not standard.Subject to COA.

Application area

Solvent-based coatings

Properties

Excellent weather resistance.
excellent flexibility, the elongation 105-110% of coating on TPU substrate.
The oily pen on TPU substrate does not shrink, and alcohol can wipe away the residue.
Good chemical resistance and solvent resistance, such as denatured alcohol, gasoline and lubricating oil. ?
Heat repairable.
No slip.

Storage stability

Store in a cool, dry place in the unopened original packaging for 36 months. Products that exceed the storage period can continue to be used after passing the inspection. It must be closed immediately after use.

Note：
1.NCO% of N3390=19.6, produced by Covestro, Germany.
2. Selection of desiccant: it is recommended to use environment-friendly desiccant for TPU base material, dilute it to 1% solid content in advance, and then add about 1%. The coating has a long activation period and will not gel when stored at 25 ℃ for 24 hours; TPH base material is not suitable for environment-friendly desiccant and cannot be dried under normal baking conditions. It is recommended to use organotin desiccant, dilute it to 10% solid content in advance and add 0.5 ~ 1%. The activation period of the coating is 2.5-3.5 hours at 25 ℃
3. It is recommended to bake at 100-130 ℃ for 2-3 minutes, cool and roll, and continue to mature at about 60 ℃ for 24-48 hours.

Application suggestion for paint protective film

Instructions:

1.The test results in the table are based on the following conditions:
baking time: 120 ℃ for 3min, curing conditions: 60 ℃ for 48h,
coating thickness: TPH substrate: 8-10 μ m   TPU base material: 15-20 μ m 
in view of the variability of substrate, film thickness, baking and curing conditions, the data provided in this table are for reference only.
2.Oil pen is used for pollution resistance test. The test method is to write on the film and place the film at room temperature for 3 min
3.Reference to solvent resistance test method: the forthcoming standard for automotive paint protective film has been submitted for approval and is to be issued.
