Product Overview
This Cationic Ink Absorption Coating for fabric digital transfer printing (DTF) is an aqueous-based formulation supplied as a milky white to light yellow liquid. Specifically engineered as a water-peelable primer layer for DTF transfer films, this Cationic Ink Absorption Coating leverages its cationic functionality to electrostatically bind anionic pigment ink particles upon contact, achieving instantaneous ink setting that eliminates bleeding, coalescence, and water-edge effects. The solids content is precisely controlled at 25±2% by weight, ensuring an optimal coating film thickness that accommodates high ink loading while permitting fast drying—critical for industrial digital printing productivity. The pH value is maintained between 4.0 and 6.0 (measured at 25°C), an acidic condition that preserves the cationic charge density and promotes consistent ionic interaction with ink formulations. With a Brookfield viscosity below 2500 mPa·s at 25°C, this Cationic Ink Absorption Coating exhibits excellent flow and leveling behavior, enabling uniform, defect-free application via roll coating or spray coating methods. In DTF fabric printing, it delivers vibrant color reproduction and sharp image resolution owing to its strong ink-absorbing capability. Furthermore, its water-peelable nature ensures clean, residue-free film release after heat lamination, coupled with outstanding die-cutting and stripping performance for efficient post-processing. For storage, the product remains stable for three months at 20°C when kept in its original, unopened packaging. The recommended storage temperature range is 5°C to 30°C. Freezing, prolonged exposure above 30°C, or contamination by bacteria, fungi, or algae must be avoided, as such conditions may irreversibly alter viscosity and particle size distribution, eventually causing sedimentation or spoilage.

Key Features
- Rapid Ionic Ink Fixation for High-Definition Prints:This Cationic Ink Absorption Coating — a superior Cationic Ink-absorbing Coating — leverages its inherent positive charge to instantly attract and immobilize anionic pigment inks upon contact. By eliminating lateral ink migration and preventing dot gain, this coating ensures exceptionally sharp image edges, high color saturation — a hallmark of a high color saturation cationic coating — and a complete absence of water-edge effects. The result is a flawless ink-receptive layer that enables high-resolution DTF printing on various fabrics without sacrificing printing speed.
- Effortless Water-Peelable Release and Superior Die-Cutting Performance:Engineered for seamless post-processing, this Cationic Ink Absorption Coating forms a cohesive film that exhibits controlled adhesion to the PET carrier. After hot-press lamination, it allows clean, residue-free water-peelable separation—a critical requirement for efficient DTF workflows. Moreover, this Cationic Ink Absorption Coating possesses the optimal balance of film rigidity and flexibility, delivering excellent kiss-cutting and stripping properties. Intricate patterns can be precisely cut and weeded without tearing or edge fraying, enhancing production yield.
- Consistent Coating Application with Defect-Free Surface: Formulated with a solids content of 25±2% and a Brookfield viscosity below 2500 mPa·s (at 25°C), this Cationic Ink Absorption Coating exhibits outstanding flow and leveling behavior. It can be uniformly applied by roll or spray coating methods, forming a smooth, pinhole-free, and snowflake-free film. The pH is maintained between 4.0 and 6.0 (at 25°C) to stabilize the cationic charge density, ensuring reliable long-term performance. When stored in original sealed packaging between 5°C and 30°C, the product remains stable for three months at 20°C, provided it is protected from freezing and microbial contamination.

Applications
- DTF Transfer Film Production for Textile Printing:This Cationic Ink Absorption Coating — an excellent ink-absorbing coating, cationic ink-absorbing coating, and no water‑edge defect coating — is specifically designed as the primary ink-receptive layer on PET release films for direct-to-film (DTF) digital transfer printing. When applied via roller or spray coating, it forms a uniform, defect-free film that instantaneously immobilizes anionic pigment inks through electrostatic interaction. The resulting printed transfer exhibits no water-edge effect, superior color brightness, and precise dot definition. Moreover, this coating enables controlled adhesion to the carrier film, allowing clean water-peelable separation after hot-press lamination — an essential performance attribute for high-throughput textile printing operations.
- Apparel Decoration and Custom Fabric Transfer:Engineered for the garment decoration market, this Cationic Ink Absorption Coating — functioning as one of the leading ink receptive coatings and a high color saturation cationic coating — delivers outstanding ink absorption and release characteristics across a broad spectrum of fabrics, including cotton, polyester, nylon blends, and elastic sportswear materials. It supports the production of high-resolution, full-color transfers with exceptional color saturation and fine-line fidelity. The coating’s excellent die-cutting and kiss-cutting properties allow intricate logos and patterns to be weeded without tearing or edge fraying. By using this coating, converters can achieve consistent, professional-grade results for customized T-shirts, team uniforms, fashion apparel, and soft signage applications.
- Industrial Roll-to-Roll Coating for High-Volume Manufacturing:Formulated with a solids content of 25±2% and a viscosity below 2500 mPa·s (at 25°C), this Cationic Ink-absorption Coating is fully compatible with high-speed industrial coating lines, including gravure, slot-die, and curtain coating systems. Its excellent flow and leveling behavior prevent common coating defects such as pinholes, snowflaking, and water marks, ensuring high production yields. The acidic pH range (4.0–6.0) stabilizes the cationic charge throughout the coating process, guaranteeing reproducible ink-fixing performance. When stored between 5°C and 30°C in original sealed packaging, this coating maintains consistent viscosity and particle size distribution, making it a reliable choice for large-scale DTF film manufacturers.
