Product Description Product Description The chemical storage tank is an very important equipment in a chemical factory, once the tanks get leaked or damaged, it will not also cause property lose but also hurt the workers. STWD9594 is a high performance one component moisture cure polyurethane coating material, the coating adopts large amount of urea bond, two urea bond, urethane bond and hydrogen bond during the pre polymerization process, it is cured after absorption with air moisture, the dense cross-linked interpenetrating network make the coating film has robust chemical resistance and physical property. It has excellent infiltration and permeability characteristics, and it will react with the hydroxyl bond of the substrate so that the adhesive strength is greatly improved with chemical and physical adhesion. In the storage tanks internal wall application, STWD9594 coating can be applied matching with special primer, it can also be used as a bottom integration material.Features and advantages* excellent adhesive strength, bond solid with carbon steel and concrete * high solid content and meet the requirements of environmentally friendly*excellent mechanical property, wearable, impact resistance and scratch resistance; flexible coating to resist the cyclic stress*excellent waterproof property*excellent anticorrosion property and resistance to many chemical rust medium such as salt spray, acid rain etc.*can be applied by hand brush or machine spraying*single component, easy to apply, and easier to guarantee the coating quality.Typical use Anticorrosion protection for the storage tanks internal wall of various chemical, petroleum, pharmaceutical, power generation industry Product informationItemResultsAppearance Color adjustableViscosity (cps )@20oC380Solid content (%)≥75surface dry time (h)1-3Pot life (h)1htheoretical coverage0.14kg/m2(thickness 100um)Physical property ItemTest standardResults pencil hardness GB/T 6739-20062Hbending test (cylindrical mandrel) mmGB/T 6742-19861breakdown resistance strength (kv/mm)HG/T 3330-1980250impact resistance (kg·cm)GB/T 173260resistance to temperature changes (-40--150oC) 24hGB/9278-1988Normal adhesive strength (Mpa), metal baseASTM D-33595A (highest)density g/cm3GB/T 6750-20071.1Chemical resistance Acid resistance 50% H2SO4 or15%HCl,30dNo rust, no bubbles, no peel offAlkali resistance 50%NaOH, 30dNo rust, no bubbles, no peel off Salt resistance, 80g/L,30dNo rust, no bubbles, no peel offSalt spray resistance, 2000h No rust, no bubbles, no peel offOil resistance 0# di esel, oil, 30dNo bubbles, no peel off( For reference: pay attention to the influence of ventilation, splash and spillage.
