UV shadowless adhesive glue _ _ _ ultraviolet UV-curable glue Appearance: Transparent Viscosity: 4000-4500cps Hardness: 77D Temperature range: -50--120 ℃ fixed time: 5S light intensity:> 10mW / cm2 Delivery date: In Stock Packing: 250g / support 1KG / bottle UV glue, also known as UV shadowless glue or gum, is a one component UV visible light curing modified acrylate structural adhesive. English UltravioletRays UV is the abbreviation of the UV light. Ultraviolet (UV) is invisible, is a piece of electromagnetic radiation outside the visible light wavelength in the range of 10 ~ 400nm. It means to be cured by ultraviolet light irradiation to a class of adhesives, which can be used as the binder, but also as paints, coatings, inks and other plastic materials use. UV adhesive curing principle is the UV-curable material photoinitiator (or photosensitizer) under UV irradiation to produce reactive free radicals after absorbing ultraviolet or cationic, causing monomer, crosslinking and then branching chemical reaction, so that the adhesive agent within seconds by the liquid into a solid. Features: 1. Fast curing reaction can be controlled; solvent-free, pollution-free; suitable for automated operations; 2. Extensive material bonding, high bonding strength, structural bonding, widely used surface; 3. Excellent optical properties; colorless and transparent glue, after curing light transmittance of> 99%, with groups of plastic known; 4. Excellent weather resistance, non-yellowing; 5. The disadvantage is that you must be sticky side light, curing equipment needed to cure; UV shadowless adhesive glue _ _ _ ultraviolet UV curing adhesive
