Benefits of Cellulose Acetate Butyrate in Formulations

Cellulose acetate butyrate is valued for its combination of cellulose-derived chemistry and polymeric performance.

Depending on the grade and formulation, CAB can help support:

Final performance should always be confirmed through formulation testing.

CAB-381-0.5 for Coating Formulations

Coatings manufacturers can evaluate CAB-381-0.5 when developing systems that require a combination of film-forming ability and controlled surface properties.

CAB can interact with resins, solvents, pigments, plasticizers, and other additives. Therefore, the selection of the CAB grade should be based on the complete formulation rather than on viscosity alone.

Laboratory evaluation can help determine the appropriate addition level and compatibility with the selected coating system.

CAB-381-0.5 for Printing Inks

Cellulose acetate butyrate can be used in selected printing ink formulations as a functional polymer component.

Depending on the ink system, CAB may contribute to:

• Film formation

• Surface appearance

• Drying behavior

• Resin compatibility

• Formulation stability

• Print surface performance

The recommended grade and dosage should be determined through testing with the actual pigment, resin, solvent, and additive system.

How to Choose the Right CAB Grade?

Selecting a CAB grade requires consideration of both raw-material characteristics and final product requirements.

For new formulations, laboratory-scale compatibility testing is recommended before commercial production.

CAB-381-0.5 Quality Control

Consistent raw-material quality is important for manufacturers using CAB in commercial formulations.

Typical quality-control parameters may include:

• Appearance

• Viscosity

• Moisture

• Ash content

• Acetyl content

• Butyryl content

• Solubility
