High solids, low viscosity, and medium hydroxyl content; delivers high gloss and excellent fullness. Suitable for use as topcoats for construction machinery, as well as solid-color finishes and clearcoats for motorcycles. Features superior weather resistance (QUA 1000h+).
The High-Solids Acrylic Resin DS-2370 represents a breakthrough in modern coating formulations, meticulously synthesized from a precise copolymerization of (meth)acrylate and specialty monomers. Visually, the resin presents as a flawlessly transparent liquid, completely devoid of mechanical impurities, ensuring that the final clearcoat maintains pristine optical clarity and a mirror-like finish. By utilizing butyl acetate as its primary solvent carrier, the formulation achieves a delicate balance between flow dynamics and evaporation rates.
When applied, the coating levels smoothly across complex geometric surfaces, such as motorcycle fairings and automotive body panels, before curing into a robust, high-gloss film. The tactile result is a glass-smooth surface that resists environmental degradation, chemical spills, and mechanical abrasions. For large-scale production facilities, this translates to fewer application defects, reduced volatile emissions due to its high solid nature, and a significantly accelerated drying profile that optimizes the entire finishing line throughput and reduces energy consumption during the baking phase.
Formulators and coating engineers require precise chemical metrics to ensure seamless integration into existing paint systems. The following technical parameters dictate the cross-linking density, reactivity, and ultimate film integrity of the DS-2370 resin. With a tightly controlled hydroxyl content and an optimized acid value, this resin provides predictable, consistent curing when paired with aliphatic polyisocyanates. The high solids concentration guarantees excellent build and fullness, while the low viscosity ensures effortless sprayability without the need for excessive thinning solvents.

Our acrylic resin is engineered to address the most critical pain points in industrial coating applications, delivering tangible improvements to both the application process and the final product lifecycle.
Exceptional Gloss and Fullness: The elevated solids content (70±2%) ensures that every pass of the spray gun deposits maximum resin, resulting in a thick, luxurious clearcoat. This translates to a deep, mirror-like finish that elevates the visual appeal of motorcycles and luxury vehicles, giving them a premium showroom aesthetic.
Accelerated Drying Profile: Engineered for high-throughput coating lines, the specific monomer composition and butyl acetate solvent system facilitate rapid solvent release. Facilities can significantly reduce flash-off and baking times, thereby lowering energy consumption and increasing daily output yields.
Superior Chemical and Weather Resistance: Once fully cross-linked, the resulting paint film forms an impenetrable barrier against harsh environmental elements. It effortlessly repels automotive fluids, road salts, and acidic contaminants, while its UV-stable backbone prevents yellowing or chalking even under intense solar exposure.
Optimized Viscosity for Application: Despite its high solid nature, the resin maintains a remarkably low viscosity (V-Z seconds). This unique rheological property allows for excellent atomization during spraying, ensuring a smooth, orange-peel-free surface finish without the excessive use of VOC-heavy reducers.
Understanding the rigorous demands of modern manufacturing, this resin is designed to provide comprehensive solutions from the mixing room to the final inspection bay.
The "high-solid, low-viscosity" architecture is the cornerstone of this resin. It perfectly balances film-forming quality with application efficiency. Paint manufacturers benefit from formulating low-VOC coatings that comply with stringent environmental regulations without sacrificing the high gloss and fullness demanded by the automotive industry.
DS-2370 is primarily designed for use in conjunction with the trimer (N-3390) to formulate topcoats or clearcoats. Its exceptional compatibility makes it the resin of choice for automobiles, motorcycles, construction machinery, and other outdoor structures requiring long-lasting protection.

Below are some of the most common technical inquiries we receive from formulation engineers and procurement specialists regarding the DS-2370 acrylic resin.
For optimal cross-linking density and film performance, DS-2370 is designed to be paired with an aliphatic polyisocyanate trimer, specifically N-3390. The exact stoichiometric ratio should be calculated based on the 3.0% theoretical hydroxyl content of the solid resin, ensuring a complete reaction for maximum weather and chemical resistance.
Butyl acetate acts as a medium-evaporating solvent. It provides enough open time for the coating to flow and level perfectly, eliminating brush marks or orange peel, while still facilitating a rapid overall drying profile compared to heavier, slower-evaporating solvent alternatives.
Yes. While it excels in high-gloss clearcoats due to its transparent nature and chroma of <1, its excellent pigment wetting properties make it highly suitable for formulating solid color topcoats, as demonstrated in our reference formula utilizing Titanium Dioxide.
The resin should be stored in tightly sealed containers within a cool, dry, and well-ventilated warehouse. Because it contains butyl acetate, it must be kept strictly away from direct sunlight, open flames, and strong oxidizing agents to ensure safety and maintain the resin's shelf life.
This characteristic allows formulators to create coatings that require less volatile solvent reduction to achieve sprayable viscosities. This not only helps in meeting strict VOC emission regulations but also allows operators to apply higher film builds in fewer coats, significantly boosting production efficiency on the factory floor.
