刷流水赚钱是真的吗description: fx-489 epoxy sealer is a 100% solids, moisture-insensitive epoxy coating. fx-489, mixed at 2 :1 by volume ratio, produces a beautiful, high gloss abrasion resistant coating. it can be applied to dry or damp concrete,wood, or steel surfaces. advantages: can be applied to concrete, wood, steel or other coatings high gloss finish no offensive solvent odor easy to apply whe to use: as a tough, chemical and abrasion-resistant floor coating on concrete, wood or steel, where ease of cleaning is important. fx-489 has been used for other applications and is not limited to floors only. physical propties: color clear pot life @ 72°f 45 mins. tensile strength astm d 638 5,000 (14 days) tensile elongation astm d 638 7.5% (14 days) compressive strength astm c 109 mod. 6,000 (7 days) viscosity viscometer 600 cps surface preparation: for best results, areas to receive fx-489 should be free of dirt, grease and heavy laitance, which will affect the bond. cleaning existing floor with solvent is recommended for surface preparation. mixing: combine two (2) parts of component ""a"" and one (1) part component ""b"", by volume, in the quantity desired and mix fx-489 with a low speed drill and fx-mixing paddle for three (3) minutes. scrape sides and bottom. avoid entrapping air while mixing. apply immediately after mixing. application: apply by brush, roller, spray or squeegee. covage: fx-489 will give an approximate coverage of 200 sq. ft./gallon at a dry film thickness of eight (8) mils. coverage will decrease when applied to a rough surface. tack-free time is subject to ambient and surface temperatures. shelf life: 2 years packaging: fx-489 is packaged in three 3 gallon, fifteen 15 gallon, and 165 gallon units. caution: ""a"" component contains epoxy resin. dang! ""b"" component contains alkaline amines; strong sensitizer. may cause skin sensitization or other allergic responses. use with good ventilation, particularly if material is heated or sprayed. prevent all contact with skin or eyes. wear protective clothing, goggles, gloves and/or barrier creams. keep container closed when not in use. wash thoroughly after handling. first aid: in case of skin contact, immediately wash with soap and water. in case of eye contact, flush eyes with copious amounts of water for at least fifteen (15) minutes. remove contaminated clothing and shoes. if irritation persists, seek medical attention. wash clothing before reuse.
