Product Advantages
When used in coatings, Cellulose Acetate Butyrate 551-0.2 offers several benefits:
1. It creates clear and smooth films.
2. It reduces unwanted surface stickiness and spotty appearances.
3. It minimizes cratering defects.
4. It improves the flow and thermal reflow properties of the coating.
5. It provides strong adhesion between coats and excellent resistance to UV light.
6. It is particularly useful in durable coatings that form strong cross-links.
CAB Resin 551-0.2 is also very versatile because it can be combined with various resin systems and dissolved in a wide range of solvents. This makes it a useful additive in many different coating formulations.
