standard.Subject to COA.
Application system
Solvent-based system
Properties
Increase slip. Improve hydrophobicity and oleophobicity.
Provide anti-marker wiping performance.
Provide lotus effect.
Compared with anti-graffiti additive, better easy-to-clean effect and alcohol-resistant wiping performance.
Water contact angle＞100°
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. Usage recommendation for defoamer
Add WE-D980 with 0.01% to PU varnish and no affecting of compatibility.
Can increase the addition to 0.1% of WE-D980 to color paint.
2. NCO% of N3390=19.6, produced by Covestro, Germany.
3.The mixed part A and B should be used up within 5-7 hours in a sealed container. Otherwise, the mixed material will be gelled.
4.Suggest dry it at 110-130℃ for 2-3min. for automotive protective film, ripening at 60-80℃ more than 24h. Dry it at 80℃ for 1h, or 150 ℃ for 5h for other industrial coatings. The advantages and disadvantages of fouling resistance and aging resistance depend on whether the coating is fully cross-linked; it is an effective method to put the surface treated film into the ripening box. It takes at least 24 hours during ripening, and the effect is better if it can reach more than 48 hours.

Instructions:
1. Baking conditions :110-130℃ 3min
Maturation conditions: 80 ℃ 48h
Coating thickness: TPH base 8-10μm TPU base 15-20μm
In view of the variability of substrate, film thickness, baking and aging 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. The brand of carburetor cleaner used in chemical resistance test is Bontny.
