DescriptionThe black Nitrile Butadiene Rubber (NBR) coating can be applied on one or both sides of flat metal substrates (cold-rolled steel or stainless steel) to provide adhesion, insulation and temperature resistance for industrial sealing and structural components.
General- Good adherence to substrate.
- Excellent noise damping.
- Adjustable coating thickness according to application requirements.
- High resistance to oils and solvents.
- Conformability and flexibility under bending.
Product behaviour (test summary)- Total coating thickness — Standard: EN 13523-1 / ASTM D1005; Unit: μ; Result: > 20; Observation: Depending on final use.
- Resistance to rapid deformation — Standard: EN 13523-5 / ASTM D2794; Unit: joules; Result: 18; Observation: No detachment.
- Adherence (pull-off) — Standard: ISO 4624 / ASTM D4541; Unit: MPa; Result: 2.5; Observation: No coating lifting.
- Cross-cut test — Standard: EN 2409 / ASTM D3359; Result: score 0; Observation: No detachment.
- Resistance to MEC friction test — Standard: EN 13523-11 / ASTM D5402; Result: DF > 50.
- Resistance to anti-freeze liquid (≥50% ethanol) in autoclave (120°C, 1.03 atm) — Visual: Pass; Observation: No detachment after cross-cut test.
