The conventional surface preparation for painting steel involves near white blast cleaning according to procedure SSPC SP-10. This level of grit blasting is costly, time consuming and is an environmental issue because of the large amount of hazardous waste produced.
NANOMYTE® PT-20 is a thin nanocomposite pretreatment that acts as a bonding agent between the metal substrate and primer. Excellent adhesion enables reduction of grit blasting from SP-10 to SP-6, or even SP-3 in less corrosion prone areas.
