Description

Releasin CAS NO 9002-69-1 is a high-purity, water-soluble polymer belonging to the polyvinyl alcohol family, widely recognized for its excellent film-forming, emulsifying, and adhesive properties. This versatile chemical is critical for industries requiring reliable binding agents and protective colloids that offer consistent performance. It is an essential raw material for manufacturers in the adhesives, paper, textiles, and construction sectors seeking to enhance product quality and process efficiency.

Application

• Adhesive Formulation: Serves as a primary binder and thickener in water-based adhesives for wood, paper, and packaging.
• Paper Manufacturing: Used as a coating agent and strength additive to improve surface gloss, printability, and tear resistance.
• Textile Sizing: Acts as a warp sizing agent to protect yarns during weaving, offering easy removal and biodegradability.
• Construction Chemicals: Functions as a non-redispersible polymer powder in cement-based tile adhesives, grouts, and self-leveling compounds.
• Polymerization Aid: Employed as a protective colloid and stabilizer in the emulsion polymerization of vinyl acetate and other monomers.
• Film Production: Utilized to produce water-soluble films for unit-dose packaging of agrochemicals, dyes, and detergents.

Quality Control

Our Releasin is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Key parameters such as degree of hydrolysis, viscosity, and purity are rigorously tested against established specifications. Certificates of Analysis (COA) documenting these results are provided with each shipment 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). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product properties.
