Scratch resistance is a key factor that defines coating durability and surface aesthetics. A high-performance coating must resist impact, abrasion, and color fading over time. Uralac, known for its excellent scratch resistance, protects surfaces through advanced polymer structure and outstanding hardness.
WHAT IS URALAC? MAIN FEATURES OF POLYESTER RESIN
Uralac is a carboxyl-functional polyester resin developed for high-performance powder coatings. When combined with TGIC or non-TGIC curing systems, it forms a strong cross-linked polymer network. This structure improves hardness, gloss, and abrasion resistance of the coating film.
The surface formed by Uralac is smooth, uniform, and naturally glossy. Its stable molecular structure minimizes coating defects and cracking while improving adhesion. Uralac also offers high thermal stability. It does not degrade during curing and maintains color consistency, preventing chalking or fading over time.
HOW URALAC ENHANCES SCRATCH RESISTANCE
Cross-linked polyester network – creating a harder coating film
The carboxyl groups in Uralac react with epoxy or hydroxyl groups in the curing agent, forming a durable three-dimensional polymer network. The dense cross-linking distributes stress evenly under mechanical impact, preventing cracking and delamination. Coatings with Uralac show 20–25% higher scratch resistance than those using conventional polyester resins.
Smooth surface – reducing friction and visible scratches
Uralac creates a uniform coating surface with minimal defects, reducing friction during physical contact. Its stable flow-out behavior ensures an even film thickness with no marks or thin areas. As a result, Uralac coatings retain their gloss and resist scratches even under frequent use.
Superior heat and chemical resistance
The polymer structure of Uralac remains stable under high temperatures without softening or losing gloss. In cold conditions, the coating stays flexible and does not become brittle. The resin resists mild solvents, cleaning agents, and UV exposure, ensuring long-lasting color and durability even in harsh environments.
REAL-WORLD APPLICATIONS OF URALAC IN COATING INDUSTRIES
Home appliance coatings
Uralac is widely used in powder coatings for refrigerators, washing machines, ovens, and kitchen appliances. The coatings achieve high gloss, excellent color stability, and superior scratch resistance. Uralac-based finishes also offer improved anti-stain properties, making surfaces easier to clean and maintain.
Metal furniture coatings
In the furniture industry, Uralac ensures long-lasting, stable coatings that resist scratches during transport and assembly. The bright, glossy finish enhances visual appeal and perceived product quality. Uralac is compatible with various pigments and effect agents, allowing flexible color design and finishes such as matte, deep gloss, or metallic shimmer.
Industrial and automotive coatings
Uralac is ideal for coating metal parts, frames, and outdoor equipment. Its excellent UV, heat, and chemical resistance keeps surfaces durable for years. The coating withstands humidity, oil, grease, and mild solvents without losing adhesion or color.
