In leather surface finishing, high-gloss printing coatings, and flocking printing adhesives, formulators frequently face technical bottlenecks such as excessive film hardness, lack of delicate tactile feedback, insufficient adhesion, and wash durability falling short of apparel standards. Traditional polyurethane resins often struggle to strike the ideal balance between an ultra-soft hand-feel and wash-resistant performance.
To provide an innovative resin binder delivering both extreme softness and strong adhesion, Senova developed waterborne-pud-rs-tc0322 (RS-TC0322 waterborne polyurethane dispersion). As an anionic aliphatic waterborne polyurethane dispersion, waterborne-pud-rs-tc0322 integrates an ultra-soft adhesive film akin to self-adhesive materials, a “silicone-like” surface effect when combined with a curing agent, superior surface pressure-sensitive bonding performance, and exceptionally high gloss. It serves as an ideal resin binder for high-end leather finishing, high-gloss printing, and flocking adhesives.
1. Why Choose waterborne-pud-rs-tc0322?
While maintaining a fine and uniform emulsion structure, waterborne-pud-rs-tc0322 provides four core technical advantages for industrial coatings and printing pastes:
- ☁️ Ultra-Soft Film with a Distinct “Silicone-Like” Touch waterborne-pud-rs-tc0322 forms an extremely soft film comparable to self-adhesive materials. When combined with a curing agent, it imparts a unique “silicone-like” surface feel and smooth texture, significantly increasing the end-product’s value.
- ✨ High Gloss & Pressure-Sensitive Adhesion The emulsion film delivers exceptionally high gloss alongside outstanding surface pressure-sensitive bonding performance, making it well-suited for demanding high-gloss coating and lamination processes.
- 🌊 Aziridine Crosslinking for Apparel Wash Requirements The resin coating inherently exhibits excellent water resistance. When compounded with 3% aziridine curing agent, the crosslinked network easily fulfills the strict washing requirements for clothing.
- 🔀 Excellent Acrylic Compatibility & Emulsion Stability Featuring a fine, uniform particle structure, waterborne-pud-rs-tc0322 exhibits good compatibility with other acrylic resins and can be blended seamlessly with our other anionic waterborne polyurethanes.

4. Sinergia na dispersão de pigmentos e otimização de aditivos
When compounding high-gloss leather finishes or flocking printing pastes using waterborne-pud-rs-tc0322, pigment wetting and system leveling dictate final film clarity and touch uniformity.
To guarantee uniform spreading without cratering or pinholes during large-scale application, pair this resin with hyperdispersants, wetting agents, and defoamers from our sister site www.rk-chem.com. Os aditivos de alta eficiência atuam de forma sinérgica com waterborne-pud-rs-tc0322 to maximize its silicone-like haptic response, high gloss, and wash durability.
