Fig. 5 Housing material
Individually marked cap and base SNL housings are made of grey cast iron.
Paint, corrosion protection
SNL housings are painted black (RAL 9005)
using a water based alkyd/acryl paint. The
paint protects the housing in accord ance with
ISO 12944-2, corrosivity category C2 (i.e.
exterior atmospheres with low level of pollu-
tion, interior atmospheres where condensa-
tion may occur). The paint is not affected by
most lubricating and engine oils, cutting fluids
or alkalescent washing chemicals. Housings
can be repainted with most water or solvent
based 1- or 2-component paints.
Unpainted surfaces are protected by a solv-
entless rust inhibitor.
