China Cellulose Acetate Butyrate CAB-531-1

CAB-531-1 achieves an exceptional balance between drying speed, leveling effect, metal pigment orientation control, and compatibility through its unique molecular structure, making it a key additive for enhancing coating performance and production efficiency.

CAB-531-1' Moderate butyryl /acetyl ratio delivers excellent solubility, flexibility, and water resistance. Higher hydroxyl content ensures superior reactivity with various cross linking resins (e.g., polyurethane, amino resins). Medium viscosity facilitates handling and provides effective viscosity support for coating systems.

Typical Properties:

Remark:

1. Viscosity to be tested by Ubbelohde viscometer 0.24mm

2. Solution to test color and haze: 20% CAB 80% Ethyl Acetate .

3. To measure Color number by Pt-Co color scale, and to measure Haze by turbidimeter.

Advantages:

Our CAB-531-1, developed over a decade of R&D and through close collaboration with domestic and international end-users, has been optimized and continuously innovated in process design, equipment selection, and automation control. This results in the following advantages:

1. Annual production capacity of 10,000 tons ensures exceptional supply stability, diversity, and security.

2. Exceptional cost-effectiveness, reducing end-user procurement costs by approximately 30%.

3. Supports customized product parameters to deliver competitive solutions tailored to client needs.

4. Rapid solvent release and accelerated drying speed. CAB-531-1 significantly accelerates paint surface drying time, boosting production efficiency, reducing dust particle damage to paint surfaces, minimizing solvent retention time, and thereby enhancing paint surface quality.

5. Superior metal pigment orientation control. CAB-531-1 effectively guides effect pigments like aluminum powder and pearlescent pigments to align highly parallel to the substrate within the paint film.

6. Superior Flow and Anti-Sag Performance. CAB-531-1 markedly improves coating leveling, facilitating the formation of smooth, mirror-like, high-gloss film surfaces. Simultaneously, it imparts excellent thixotropy to coatings, providing outstanding anti-sag properties during vertical application and enabling thicker film thicknesses in a single spray pass.

7. Outstanding Compatibility and Reactivity. CAB-531-1 exhibits excellent compatibility with acrylic, polyester, and amino resin systems. Due to its high hydroxyl content, CAB-531-1 can participate as a co-reactive resin in the crosslinking network of polyurethane or amino bake coatings, thereby enhancing the final hardness, chemical resistance, and durability of the coating film.

Applications:

With its balanced and outstanding performance, CAB-531-1 has become an indispensable key component in the following fields:

1. Automotive Coatings. As a core control agent, CAB-531-1 provides fast drying, exceptional metallic effects, and good repairability for metallic base coats.

2. Refinish Coatings. CAB-531-1's fast-drying properties align perfectly with refinish shops' efficiency demands.

3. Wood Coatings. Used on furniture, flooring, etc., CAB-531-1 delivers fast-drying, high-leveling, high-transparency, and high-hardness surface coatings, ideal for high-efficiency production line applications.

4. General Industrial Coatings. CAB-531-1 also finds broad application in home appliances, agricultural machinery, metal furniture, and similar products as a functional additive enhancing drying speed and appearance.

5. Plastic Coatings. CAB-531-1 can be applied to rigid plastic substrates (e.g., ABS, PC) to deliver a hard, wear-resistant coating.
