KDD 718 from KDD Chemicals' fully alcohol-soluble low-odor universal thermoplastic acrylic resin series is a modified alcohol-soluble resin designed for multi-system primers and environmentally friendly coating scenarios. Using high-purity ethanol as solvent, this resin is transparent to slightly emulsified liquid with 50% solid content, featuring fully alcohol-soluble property and low-odor advantage
Fully alcohol-soluble, environmental and low-odor - Completely soluble in ethanol, pure solvent system, low-odor, meeting strict environmental coating standards.
Universal for three primers - Compatible with rubber, PU and UV primer systems, high versatility, reducing formula R&D costs.
Excellent protective performance - Outstanding water resistance and weather resistance, stable coating after film formation, capable of resisting complex environmental erosion.
Efficient construction features - Fast drying speed, greatly shortening construction cycle; good anti-adhesive-burning property, suitable for sensitive substrate coating.
Universal primer for multi-systems: Preparation of rubber primer, PU primer and UV primer, adapting to diverse coating systems and simplifying supply chain management.
Environmental plastic toy paint: Production of low-odor single-component plastic paint and toy paint, meeting toy safety standards and ensuring use safety.
Alcohol-soluble wood protective paint: Protective coating for wood surfaces, good water resistance, avoiding wood moisture deformation and improving product durability.
High-end printing ink: Preparation of alcohol-soluble ink, suitable for printing on paper, plastic and other substrates, with strong adhesion and excellent printing adaptability.

Q1: What are the primary processing methods suitable for KDD718?
A: KDD718 is designed for thermoplastic processing techniques including extrusion, injection molding, and solution coating. Its low melt viscosity and excellent thermal stability support consistent flow and minimal degradation during standard polymer processing.
Q2: How does KDD718 enhance surface properties in coatings and inks?
A: As a film-forming binder, KDD718 contributes clarity, gloss retention, and improved mar resistance. It also enhances substrate adhesion—particularly on plastics and metallized films—without compromising flexibility or recoatability.
Q3: Is KDD718 compatible with common plasticizers and other acrylic or vinyl resins?
A: Yes, KDD718 demonstrates good compatibility with typical plasticizers (e.g., phthalate- and adipate-based types) and blends readily with other thermoplastic acrylics, nitrocellulose, and certain vinyl copolymers—enabling formulation flexibility for multi-resin systems.
Q4: What solvent systems are recommended for dissolving KDD718?
A: KDD718 dissolves efficiently in common organic solvents such as esters (e.g., ethyl acetate, butyl acetate), ketones (e.g., methyl ethyl ketone, methyl isobutyl ketone), and aromatic hydrocarbons (e.g., toluene, xylene). Solvent selection should consider evaporation rate, safety requirements, and end-use regulatory constraints.
