VINNAPAS EP 705K Comprehensive Analysis

In the rapidly evolving field of industrial adhesives, finding a product that combines strength, flexibility, and durability has always been a challenge. Today, we introduce VINNAPAS EP 705K , an innovative polymer dispersion designed for modern, demanding applications. Its unique properties provide superior solutions for a variety of complex bonding needs.

VINNAPAS EP 705K (VAE CW 40-758) is a Vinyl acetate-ethylene copolymer emulsion dispersion protected by polyvinyl alcohol (PVOH). It has a moderate viscosity and is produced without the addition of formaldehyde donors, giving it advantages in environmental friendliness and application safety. The unique main chain structure of this polymer endows the dried film with two core characteristics: strength and flexibility. More importantly, these properties are maintained even under water immersion or temperature fluctuations.

♠ Overview of Superior Adhesive Performance:

• Excellent adhesion to a variety of plastic surfaces.
• Durable and flexible bonded joints.
• High cohesion, ensuring the structural strength of the adhesive itself. Chemical stability: It remains chemically stable at both low and high pH levels.

VINNAPAS EP 705K (ULS) offers excellent compatibility, being compatible with a wide range of polyvinyl acetate (PVAc) polymers, rubber latexes, EVCL dispersions, and other VAE dispersions. It is also compatible with a variety of resins, solvents, plasticizers, and other modifiers, providing formulators with significant flexibility for product customization and performance optimization.

In terms of applications, as a multi-functional adhesive, it reliably bonds a variety of substrates, including paper, wood, cotton fabric, nylon fabric, cardboard, polyurethane foam, and certain types of coated paperboard.

♠ Key application areas

This product offers significant advantages in packaging and lamination applications, with typical applications including:

Packaging: such as windowed carton and box forming, envelope manufacturing.

• Lamination: wood lamination and low-cost veneer veneering, PVC lamination and OPP wet lamination, film-to-wood lamination.
• Other applications: Flooring installation, paper packaging and processing, bags and handbags, and textiles or interiors.

♠ Processing and Storage Recommendations

VINNAPAS EP 705K exhibits good stability on high-speed machines and is suitable for a variety of applications, including roll coating, extrusion, and spray coating.

♠ Storage Guidelines

Proper storage is crucial to maintain optimal product performance: Shelf Life: When stored in its original, unopened container at temperatures between 5°C and 30°C, the product has a shelf life of 9 months from the date of manufacture.

• Container Recommendations: Due to the weakly acidic nature of this dispersion, iron or galvanized iron equipment and containers are not recommended, as corrosion may cause discoloration. Containers and equipment made of ceramic, rubber, or enamel materials, appropriately finished stainless steel, or plastics (such as rigid PVC, polyethylene, or polyester resin) are recommended.
• Freeze Protection: Freezing of the product must be prevented.
• Pre-use Treatment: Filtration is recommended before use as the polymer dispersion may form a surface film or clumps during storage or transportation.
