Hybrid Coating
*Note
: Higher concentration of sulfates is allowed, provided the sum of chl sulfates parameters does not exceed 650 mg/l for
Baltibond/SST304L.
*Note
: In case of a HDG coil, passivation of the coil is required. During this period, both the pH and the hardness of the spray water will have
more stringent requirements. The pH must be kept between 7 and 8.2, and the hardness must be kept between 100 and 300 ppm.
