Description

Poly(Vinyl Butyrate) is a synthetic polymer derived from the esterification of polyvinyl alcohol with butyric acid. This material is valued for its excellent film-forming properties, adhesion, and flexibility, making it a versatile component in high-performance industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty chemical sectors for creating durable, protective layers and binders.

Application

As a primary film-forming agent and binder in high-quality industrial and protective coatings.
In the formulation of specialty adhesives and sealants requiring strong adhesion and flexibility.
As a key component in printing inks to enhance gloss, rub resistance, and substrate adhesion.
In the production of temporary protective coatings for metals and sensitive surfaces.
As a modifier in composite materials to improve impact resistance and interfacial bonding.
For research and development purposes in polymer science and material engineering.

Quality Control

Our Poly(Vinyl Butyrate) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in key parameters such as molecular weight distribution, degree of butyralization, and residual solvent content. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
