Before applying the anti-reflective coating, it is essential to apply an abrasion-resistant coating to maintain the optimal anti-reflective effect when using polycarbonate sheets for automotive displays. This ensures durability and clarity for a superior display experience.
When specifying abrasion-resistant polycarbonate, decide whether one or both sheet faces need a hard coat. AR1 has one coated face, while AR2 has two. The right option depends on which surfaces will be exposed to contact, cleaning, and wear during use.
AR1 has an abrasion-resistant hard coat on one face. It suits applications where the coated face can be oriented toward the main source of contact or cleaning, while the reverse face is bonded, laminated, printed, or kept protected. Confirm that the selected adhesive or ink is compatible with the uncoated face, and mark the coated side before fabrication and installation.
AR2 has an abrasion-resistant hard coat on both faces. It is suitable for freestanding panels, machine guards, and other applications where either side may be handled, exposed, or cleaned. The two-sided coating provides protection on both faces, but does not necessarily mean greater scratch resistance per face than AR1. Check the selected grade’s data for UV, chemical, and cleaning performance.
Choose AR1 when only one face needs abrasion-resistant coating and the sheet can be installed with that face toward the exposed side. The uncoated reverse face may be more suitable for bonding or printing, depending on the materials and process. Verify compatibility with the selected adhesive or ink before production.
Choose AR2 when both faces need abrasion-resistant coating because either side may be exposed during use, handling, or cleaning. Confirm that the selected grade meets the project’s requirements for weathering and chemical contact.
Indeed, while polycarbonate is a robust material, its surface is softer compared to glass, making it susceptible to scratches over time. To address this concern, manufacturers often apply a hard coating to the surface of the polycarbonate sheet. This hard coating serves as a protective layer, enhancing scratch resistance and prolonging the lifespan of the material. It is a common practice to provide this additional layer to ensure that polycarbonate maintains its optical clarity and durability, especially in applications where the sheet is exposed to potential abrasion or wear.
Polycarbonate is a durable material, but its surface is softer than glass. The exact hardness can vary depending on the specific formulation and manufacturing process, but generally, polycarbonate has a Rockwell hardness of approximately 72-75 R scale. This is softer than glass, which typically has a higher hardness.
While polycarbonate is resistant to many types of impacts and is known for its toughness, it is more susceptible to scratching than some other materials. The application of hard coatings can significantly improve scratch resistance and protect the surface from abrasion.
AR Polycarbonate(tuffak ar) typically refers to polycarbonate sheets that have Abrasion Resistant coating on polycarbonate sheet surface.
Here are the tips to make polycarbonate abrasion and scratch resistant.
Hard Coating: Applying a hard coating to the surface of polycarbonate is a widely used method. This coating forms a protective layer that increases the material’s resistance to scratches. The hard coating is often cured through a chemical process or exposure to UV light.
Anti-Scratch Coating: Anti-scratch coatings are designed specifically to reduce the susceptibility of polycarbonate to scratches. These coatings create a durable barrier that helps protect the surface from abrasion.
Abrasion-Resistant Polycarbonate: Some manufacturers produce polycarbonate sheets that are inherently more resistant to abrasion. These sheets are formulated with additives that enhance their resistance to wear and scratches.
The abrasion-resistant acrylic/polycarbonate sheets can be cleaned in the same way as standard acrylic or polycarbonate sheets. Simply use a mild soap or a soft cloth or sponge to gently clean the surface. Avoid using abrasive cleaners or rough materials that may scratch or damage the abrasion-resistant coating. Rinse thoroughly with clean water and dry with a soft, lint-free cloth to maintain the clarity and performance of the sheet.

Some grades and coatings withstand certain sterilization methods; compatibility must be validated per sterilization process (e.g., EtO, gamma, autoclave) before use.
Standard polycarbonate can scratch during use, cleaning, or handling. To improve surface durability, choose abrasion-resistant polycarbonate sheet with a factory-applied hard coat. The coating helps resist everyday scratches and wear, while preserving the sheet’s clarity and impact performance. It improves scratch resistance but does not make the surface scratch-proof.
Choose single-sided coating when only one face will be exposed, and double-sided coating when both faces may be handled or cleaned. For parts that need bending or thermoforming, confirm that the selected hard-coated grade is designed for forming, since some grades are intended for flat applications only.
