The DS-2375 is primarily designed for use in conjunction with the trimer (N-3390) to formulate topcoats or clearcoats for automobiles, motorcycles, construction machinery, and other outdoor structures, offering weather resistance exceeding 1,000 hours.
Formulating top-tier coatings requires raw materials that do more than just meet basic standards; they must actively enhance the final product. The DS-2375 hydroxyl-functional acrylic resin is engineered to deliver a multitude of operational and performance advantages.
Rapid Drying Dynamics: The unique molecular architecture facilitates accelerated solvent release, allowing the paint film to achieve touch-dry and hard-dry states in a fraction of the standard time. This translates to faster production cycles and reduced energy consumption during the baking phase.
Unrivaled Visual Brilliance: Capable of producing an extraordinary depth of gloss and a high distinctness of image. The cured film reflects light with a liquid-like clarity, giving automotive and motorcycle exteriors a premium, wet-look finish that captivates the eye.
Formidable Weather Defense: Tested to withstand over 1,000 hours of rigorous weather exposure, the resin maintains its structural integrity and aesthetic appeal even under punishing sunlight, heavy rain, and fluctuating temperatures.
Optimized Application Viscosity: Despite its high solids content, the medium-to-low viscosity profile ensures excellent leveling and atomization during spray application, preventing common defects like orange peel or sagging.
Understanding the intricate demands of large-scale coating production, the DS-2375 resin is built around six core performance dimensions that directly address the most pressing challenges faced by modern formulation engineers.
At the heart of this resin is a highly sought-after high solid, low viscosity profile. With a solids content of 75±2% and a precisely controlled hydroxyl content of 3.0%, it provides the perfect foundation for high-quality PU topcoats. The high solids nature not only ensures a thicker, more durable film per pass but also significantly lowers Volatile Organic Compound (VOC) emissions, aligning perfectly with stringent global environmental standards.
For high-end applications like automotive and motorcycle finishes, visual perfection is non-negotiable. This resin is formulated to deliver unparalleled gloss and distinctness of image (DOI). The resulting surface is incredibly smooth to the touch, offering a mirror-like reflection that instantly elevates the luxury appeal and market value of the end product.
Outdoor steel structures and heavy construction machinery face relentless environmental assaults. Engineered for survival, this resin boasts a documented weather resistance exceeding 1,000 hours. Its robust chemical resistance acts as a steadfast barrier against corrosive agents, ensuring long-lasting protection that dramatically reduces the frequency and cost of maintenance and repainting.
Time is a critical resource in any coating facility. The DS-2375 resin features exceptional rapid-drying characteristics. By drastically shortening the waiting times for surface drying and thorough curing, it accelerates assembly line throughput, minimizes bottlenecks, and cuts down on the thermal energy required for baking ovens.

To further assist your formulation and procurement teams, we have compiled answers to the most common technical inquiries regarding the DS-2375 acrylic resin.
The DS-2375 is engineered with a specific hydroxyl content (3.0%) and high solids (75±2%) that, when cross-linked with an aliphatic polyisocyanate trimer, creates a dense, highly durable polyurethane network. This results in exceptional gloss retention, superior distinctness of image (DOI), and outstanding resistance to UV degradation and chemical spills, which are critical requirements for automotive finishes.
A high solids content means more actual film-forming material is deposited on the substrate per spray pass, reducing the number of coats required. Simultaneously, the medium-to-low viscosity (Z-Z3) ensures that the paint atomizes beautifully through spray guns without the need for excessive thinning. This combination lowers VOC emissions, saves on solvent costs, and increases overall application efficiency.
Absolutely. While it is highly prized for clearcoats due to its pristine transparency (Chroma <1) and lack of mechanical impurities, it is equally effective as a binder for solid color topcoats. Its excellent pigment wetting properties, especially when used with premium additives, make it ideal for formulating vibrant, high-hiding automotive and machinery paints, as demonstrated in our reference formula utilizing Titanium Dioxide.
For optimal weatherability and chemical resistance, we strongly recommend using an aliphatic isocyanate trimer, such as N-3390. The exact mixing ratio should be calculated based on the theoretical hydroxyl content (3.0% on a solid basis) of the DS-2375 and the NCO equivalent weight of the chosen hardener, ensuring a balanced stoichiometric ratio for complete cross-linking.
The resin should be stored in tightly sealed, original containers in a cool, dry, and well-ventilated area, away from direct sunlight, open flames, and strong oxidizing agents. Since it utilizes butyl acetate as a solvent, proper grounding and explosion-proof storage protocols must be observed. When stored correctly under these conditions, it maintains excellent stability and performance integrity over its designated shelf life.
