Product Description
STWD8003 takes fluo rine copolymer resin or fluorinated olefins and other monomer copolymer as main film material, produced from scientific process. The two component anticorrosion decoration topcoat has large amount of C-F bond which is known to be the strongest molecular bond, therefore it has incomparable properties of durability, weather resistance, chemical resistance, non-stick, self-lubricating and anti-radiation.
Product features and advantages
* coating film is compact tough, full shine and colorful
* no yellowing, no powdery, no crack and anti-aging, with excellent weather resistance and color-keep property
* excellent adhesive strength, with good compatible with polyurethane, epoxy, chlorinated rubber, alkyd, phenolic and other coatings
* excellent abrasion resistance, bending and impact resistance
* excellent heat resistance and cold tolerance
* excellent chemical resistance such as acid, alkali and salt
* excellent anticorrosion property
* excellent waterproof property
* excellent durability to reduce the maintenance cost for lifelong
* extend the service life of sprayed structure
Typical use
Anti-corrosion protection, decoration works of construction, road and bridge, municipal engineering, stadiums, petrochemical, electrical and electronic industry, machinery industry, aviation and other fields.
