Water-Based Tackifying Emulsion 2158 (PU-Specific) F0326 Environmental Safety water-based polyurethane coatings
2158 is an eco-friendly water-based tackifying emulsion specifically developed for water-based polyurethane (PU) systems. Prepared through a specialized monomer polymerization process, it delivers outstanding tackifying performance, compatibility, and stability. It contains no volatile organic compounds (VOCs) and emits no irritating odors. This emulsion effectively enhances the initial tack, sustained adhesion, and peel strength of water-based polyurethane adhesives, coatings, and composite mat

I. Product Overview:
2158 is an eco-friendly water-based tackifying emulsion specifically developed for water-based polyurethane (PU) systems. Prepared through a specialized monomer polymerization process, it delivers outstanding tackifying performance, compatibility, and stability. It contains no volatile organic compounds (VOCs) and emits no irritating odors. This emulsion effectively enhances the initial tack, sustained adhesion, and peel strength of water-based polyurethane adhesives, coatings, and composite materials without compromising the system's inherent mechanical properties or weather resistance. It is widely applicable for modifying water-based polyurethane products across packaging, leather, textiles, construction, and other industries.

Features
Product Features:
1. Excellent Compatibility: Achieves uniform molecular-level mixing with water-based polyurethane resins (including anionic and nonionic types), without separation or sedimentation. Does not affect system transparency or storage stability.
2. Easy to Use: Flexibly adjust the addition amount based on water-based polyurethane product requirements to achieve different tackifying effects. Significantly enhances the initial tack and sustained adhesion of adhesives, addressing the common issue of “insufficient bonding strength” in water-based PU products.
3. Synergistic Performance Enhancement: While thickening, it optimizes the film-forming properties of water-based polyurethane, reduces film defects, and improves the flexibility and flex resistance of the coating. It has no negative impact on core system metrics such as tensile strength and water resistance, and in some scenarios, it can slightly enhance aging resistance.
4. Environmental Safety: Utilizes water as the dispersion medium, ensuring environmental friendliness and convenient storage.
IV. Product Applications:
This product is suitable for various water-based PU systems, including water-based polyurethane adhesives (e.g., composite adhesives, pressure-sensitive adhesives, footwear adhesives), water-based polyurethane coatings (e.g., wood finishes, leather finishes), and water-based polyurethane composites (e.g., artificial leather, synthetic leather).
V. Packaging:
50KG/drum, IBC containers. Store in a cool, dry, well-ventilated warehouse, avoiding direct sunlight and rain exposure.
