Applications
T-6138 is recommended for high-performance UV-curable coatings requiring extreme thinness and durability:
Ultra-Thin Optical Coatings – Anti-reflective (AR) and anti-glare (AG) layers for precision lenses, optical waveguides, and diffraction films.
Specialty Fiber Optics – Protective and functional cladding for medical, military, and telecommunications fibers.
Electronic Hard Coatings – Durable protective films for display panels, touch sensors, and flexible electronics.
Nano-Coatings for Optics & Surfaces – Where minimal thickness and maximum hardness are critical.
Formulation Guidelines
Monomers: Compatible with most standard monomers. Due to its relatively low viscosity, monomer content can be minimized to preserve optical and mechanical properties.
Solvents: Miscible with esters, ketones, and aromatic hydrocarbons. Not soluble in alcohols alone but compatible with alcohol-ether blends.
Polymers: Exhibits good compatibility with polyesters, epoxies, polyurethanes, phosphates, and other acrylates for tailored formulation.
Why Choose T-6138?
Unmatched Thin-Film Hardness – Perfect for applications where coating thickness must be minimized while maintaining scratch and wear resistance.
Optical Clarity & Function – Low refractive index and high transparency support advanced optical designs.
Robust Chemical & Environmental Resistance – Ensures long-term reliability under harsh conditions.
Formulation Versatility – Easily integrated into existing UV coating systems with wide solvent and polymer compatibility.
T-6138 resin meets the needs of cutting-edge applications where ultra-thin, high-hardness, and optically functional coatings are required. From precision optics and specialized fiber optics to next-generation electronic films, T-6138 provides a reliable, high-performance material solution.
