S857 is one-component heat curing, solvent-free sealant based on PVC/acrylate. It can be applied to clean, bare steel, or electro coat and accepts powder paint either cured or wet on wet . |
S857 is cured by heat Curing depends both on temperature and elapsed time. |
The most suitable heat sources are convection ovens. |
The minimum heating temperature is
175°C (347°F)
, while
the maximum temperature must not exceed
230°C (446°F)
.
It is mandatory to perform tests with original parts to ensure proper curing and function of the bonded part under original conditions |
For further information contact the Technical Service Department of SEPNA Industry. |
