Description

Starch, Polymer With Butyl 2-Propenoate CAS NO 75665-11-1 is a chemically modified starch derivative, created by polymerizing starch with butyl acrylate. This modification imparts enhanced film-forming, adhesive, and hydrophobic properties to the native starch, making it a valuable functional biopolymer. It is primarily sought by manufacturers in the adhesives, coatings, paper, and textile industries seeking sustainable, bio-based performance additives.

Application

• Adhesive Formulations: Used as a bio-based tackifier and binder in pressure-sensitive adhesives, remoistenable gums, and label pastes.
• Paper & Paperboard Coatings: Enhances surface strength, printability, and provides a moisture-resistant barrier in coating formulations.
• Textile Sizing & Finishing: Serves as a warp sizing agent to strengthen yarns and as a finishing agent to impart stiffness or handle.
• Biodegradable Films & Coatings: A key component in the production of water-resistant, yet compostable, packaging films and protective coatings.
• Construction Materials: Acts as a rheology modifier and binder in gypsum boards, joint compounds, and other building products.
• Personal Care & Cosmetics: Functions as a film-former, texture enhancer, and stabilizer in hair styling products, creams, and lotions.

Quality Control

Our Starch, Polymer With Butyl 2-Propenoate is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as degree of substitution, viscosity, and solids content. Certificates of Analysis (COA) documenting these parameters 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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking or degradation.
