Polyester resins including saturated polyester and unsaturated polyester, are essential components in the coatings industry. Their unique characteristics and versatility make them suitable for a wide range of applications on different substrates, from metal and wood to plastic..

Hydroxyl-functional Acrylic Resins play an essential role in the coatings industry, serving as key components in two-component polyurethane (2K PU) systems. These resins contribute hydroxyl (-OH) groups that react with isocyanate crosslinkers to form durable, high-performance coatings. Runshine produces a comprehensive portfolio of acrylic polyols, categorized by hydroxyl value, molecular weight, solid content, and solvent type—including conventional solvent-borne, high-solids, and waterborne dispersions. Products are engineered to offer a balance of reactivity, compatibility, flexibility, and resistance properties, making them suitable for a wide spectrum of coating applications.

Runshine is leading manufacturer in the field of coating additives. With years of expertise, we produce a wide range of high - quality additives. Our product line includes various defoamers to eliminate foam during production, leveling agents for a smooth and even coating surface, dispersants to evenly disperse pigments, rheology additives for better viscosity control, and wetting agents to enhance substrate wetting.These additives are extensively used in the manufacturing of coatings and inks.

Thermosetting acrylic resins effectively enhance coating bond strength on metal (aluminum, steel, galvanized iron), plastic (PP, ABS, PVC), wood, and glass—they penetrate metal surface irregularities to form mechanical and chemical bonds, modify low-surface-energy plastics for better wettability, seep into wood fibers to prevent cracking from moisture changes, and react with glass hydroxyl groups for friction-resistant adhesion. As solvent-borne additives, they blend well with coating systems to form dense films; in automotive (car bodies, bumpers), industrial (machinery, pipelines), and decorative (furniture, architectural glass) applications, they ensure durable adhesion even under harsh conditions like road salt, acid-base corrosion, extreme temperatures (-40°C to 80°C), or outdoor UV and sand.

Our Water-soluble resin product line includes high-performance acrylic and polyester variants engineered for eco-friendly and efficient coating applications. These resins are designed to deliver excellent hydration, superior hardness, boiling water resistance, and outstanding recoating performance, making them ideal for a wide spectrum of industrial water-based coatings.  

Next-Gen Adhesion Promoter is a critical component formulated to address the unique challenges of modern high-solids and waterborne coating systems, ensuring superior substrate adhesion across a diverse range of demanding applications. This advanced promoter is engineered with a novel silane-based technology that functions through covalent bonding mechanisms, significantly enhancing the interfacial strength between the coating and difficult substrates such as plastics, treated metals, and composites. Its exceptional compatibility is demonstrated by effective performance in both polar waterborne lattices and high-solids polyol/acrylic formulations, preventing delamination and ensuring long-term durability. Key properties delivered include outstanding hydrolytic stability, excellent resistance to humidity, and improved mechanical integrity of the final film. Consequently, it is ideally suited for use in automotive OEM and refinish coatings, industrial maintenance paints, and plastic coatings where robust, permanent adhesion is a fundamental requirement for coating performance and service life.
