Series 19
Special applications
Objects that are directly exposed to the salt/fog conditions of a marine environment must be coated twice t obtain a minimum film thickness a=of at least 80 microns on the edge and corners. The first coat will be cured between the range of 200 °C -4 [min] and 170 °C -10 [min]. The second coat must be cured between tha range of 200 °C -12[min], and 180 °C -22 [min]. (All cure cycles refer to substrate temperature).
Any kind of filiform corrosion will not be a cause for any claim under any warranty.
Please note
Post-bending properties of any part must be verified prior to application. Minor cracks in the coated surface may lead to corrosion.
Proper application of any packaging material is important, including but not limited to any fixing aids or means of transportation and to the ease of their post-removal (e.g. adhesive tapes). Under unfavorable storage conditions a micro climate (e.g. water and moisture accumulation under packaging foils) may lead to milky-white spots on the coated surface. This physical process only occurs occasionally and may be revered with heat (e.g. post-tempering in the oven, industrial heating device).
Non-colored coatings, e.g. clear coatings may prone to stress cracks due to the difference in material tension between the substrate and the powder coating.
Joint sealants and any other auxiliary products, such as glazing aids, gliding waxes, drilling and cutting lubricants, which come in contact with the coated surface, must be ph -neutral and free of substances which may damage the finish. Prior to coating a suitability test at the applicator is therefore highly recommended.
