What is T-6138-2 Resin?
T-6138-2 is a unique, low-viscosity UV curable resin renowned for its low refractive index and excellent adhesion to a wide range of substrates. It forms coatings with remarkably high hardness and outstanding abrasion resistance, even at sub-micron and nano-scale thicknesses.
Key Features & Performance Benefits:
Exceptional Hardness & Abrasion Resistance: Achieves >6H pencil hardness on glass and >5H on PET, providing superior scratch and wear resistance in ultra-thin film applications.
Low Refractive Index: Essential for advanced optical applications requiring precise light management.
Broad Substrate Adhesion: Reliably adheres to various surfaces, simplifying formulation for different uses.
Excellent Chemical Resistance: Withstands exposure to various chemicals, ensuring long-term durability.
Low Viscosity & Good Solubility: Features low inherent viscosity and is compatible with esters, ketones, and aromatic hydrocarbons (not soluble in alcohols alone). This facilitates easy processing and formulation.
Low Dielectric Constant & High Hydrophobicity: Offers excellent electrical insulation and water-repellent properties, ideal for electronic protective coatings.
Excellent Compatibility: Readily mixes with common monomers, polyesters, epoxies, polyurethanes, phosphate esters, and other acrylates for tailored formula adjustments.
