Description
The solvent-based primer-enamel is made in matt, semi-gloss and gloss, in black, and in BS and RAL colors. It is overcoated with itself and with other epoxy and polyurethane finishes of the same manufacturer. The chemical bond of the epoxy makes it possible to work with ferrous and non-ferrous metals and many composites. After 7 days of air drying or accelerated curing for 30 minutes at 125 °C the coating withstands 48 hours at 204 °C and 100 hours at 180 °C. In hot ASTM Fluid 101 oil at 177 °C it lasts 8 hours, in lubricating oil at 150 °C 100 hours, and in reference fuel B at room temperature 4 hours and 100 hours without peeling or softening. After heating for 48 hours at 204 °C a layer with a cross-shaped scribe withstands 350 hours of salt spray per ASTM B117. The high build per coat reduces the number of operations, which matters in repair and maintenance of rolling stock.
How to choose
Look at where the part works. For bogies and wheelsets, frames, liquid and air receivers, control cabinets and support structures the material is recommended directly. If an aviation finish is needed, see the IP3 and IP9064, and for magnesium and aluminum the Rockhard. Gloss and color, matt, semi-gloss or gloss, black, BS or RAL, are set by the project.

FAQ
Which substrates can RWIP120 be applied to?
Steel, aluminum, galvanized steel and composites, as well as ferrous and non-ferrous metals.
How many coats are needed and what can it be overcoated with?
One or two coats. It is overcoated with the material itself and with epoxy and polyurethane finishes of the same manufacturer.
What temperature does the cured RWIP120 film withstand?
After 7 days of drying or 30 minutes at 125 °C the film holds 48 hours at 204 °C and 100 hours at 180 °C.
How many hours of salt spray does the coating withstand?
350 hours per ASTM B117 with a cross-shaped scribe, after heating for 48 hours at 204 °C.
Are the VOC values, consumption and pot life of RWIP120 known?
The available materials give no specific values for VOC, consumption and pot life. They should be checked in the data sheet.
