Special protection is required for satellites and rockets in aviation industry, as common material is inadequate. SWD Company developed an special polyurea coating whose high quality has been well approved, used for satellites and rockets with perfect performance.
Characteristics
The product has high reactivity, could spray-applied forming on curved,slope and vertical surface without sagging. Insensitive to moisture and temperature. No peeling and cracking when against the impact of cold and hot circumstances. Flexible and dense coating has strong adhesion to various substrates like metal and PU insulation materials. High performance of impact and wear resistance, no pulverization when long term use outdoors. A green product, no harm to human.
