THIELE
After heat treatment the chain surface can be described as ‘natural black’. As corrosion products can form
on this surface after just a few days in storage all THIELE chains – unless corrosion protected in some
other way – are coated with Tectyl (TEC) for transport purposes. Tectyl is also a proven means for pre-
venting corrosion during storage.
The duration of the corrosion protection afforded by Tectyl will depend on the weather and climatic
conditions. Experience shows that chains whose Tectyl coatings remain intact are still fully ft for service
after several months of storage outdoors.
Tectyl also acts as a running-in lubricant in that it eases the bedding-in process (progressive initial wear)
that the chain links have to go through.

Corostar Plus (COR) is a zinc-rich paint
containing specially developed additives. It
reduces friction at the chain links and is
widely used to improve the running-in
lubrication effect – especially in the case of
plough chains.
Corostar Plus is also a very effective
medium-term corrosion protection agent
for conveyor chains.
