VINNAPAS® 4712 N

ANHUI LIWEI CHEMICAL CO.,LIMITED

[Introduction]

VINNAPAS® 4712 N is a high-performance redispersible polymer powder (RDP) specifically designed for tile adhesives, based on a vinyl acetate-ethylene (VAE) copolymer formulation with a medium glass transition temperature (Tg). It delivers an optimal balance of adhesion strength and flexibility, with exceptional bonding performance to wood substrates (e.g., plywood) – making it ideal for tile installations on wood-based surfaces. Additionally, mortars modified with this product exhibit excellent water resistance while maintaining good workability and open time, fully complying with international standards such as ANSI 118.4, ANSI 118.11 and ISO 13007-1.

[Properties]

• VINNAPAS® 4712 N is a VAE-based redispersible polymer powder (RDP) and is dispersible in water.

• Mortars modified with this product show superior adhesion to wood substrates, excellent water resistance and balanced flexibility, with stable mechanical properties.

• It complies with international tile adhesive standards (ANSI 118.4/118.11, ISO 13007-1), ensuring reliable performance in demanding applications.

• The product enhances mortar workability and open time without compromising flow properties, facilitating construction operations.

• VINNAPAS® 4712 N contains a fine mineral filler as antiblocking agent. It is produced without the addition of organic solvents, plasticizers or film-forming agents.

[Storage]

During storage, protect the product from contact with moisture and direct sunlight. Prolonged storage at temperatures above 30 °C may result in blocking. Carefully seal any open containers and store in a cool, dry warehouse. Do not store the product for more than six months from the delivery date (unless specified otherwise in the Certificate of Analysis). Verify performance before use if stored beyond the recommended period.

N Series

This series comprises versatile, basic RDPs, mostly vinyl acetate-ethylene copolymers. They have minimal impact on the rheological properties of mortar, providing basic adhesion and flexibility. With high formulation flexibility, they are commonly used as basic modifiers for dry-mix mortars.

Typical products include VINNAPAS® 4023 N, suitable for tile adhesives, plastering mortars, and self-leveling materials. It improves the bond strength, flexural strength, and abrasion resistance of mortars without affecting their leveling and water retention. Another example is VINNAPAS® 5010 N,VINNAPAS® 5044N,VINNAPAS 5005 N,VINNAPAS 5043 N,VINNAPAS® 4712N often used as a general-purpose powder in tile adhesives and putties, featuring low ash content and compatibility with various dry-mix mortar formulations.

VINNAPAS® 4712 N also belongs to this series, specifically optimized for adhesion to wood and vitrified tiles. It exhibits excellent water resistance, meets relevant international tile adhesive standards, and is suitable for formulating multi-purpose thin-layer tile mortars.
