POLSIL® MV AB

1 of 17 products in this brand
POLSIL® MV AB is addition curing, two-component liquid silicone elastomers which after the addition of a catalyst cures at room temperature. The curing time may be shortened at higher temperature (i.e. up to 6 h at 70°C). The rubber is suitable for protection of electronic and telecommunication systems against influence of external factors and for stiffening and protecting (flooding) photovoltaic cells in solar panels against impact of climatic factors in the conditions of variable temperatures ranging from -50 to +180°C.

Preparation of the Composition

100 parts by weight Polsil® MV AB or Polsil® MV AB/S – part A

100 parts by weight Polsil® MV AB or Polsil® MV AB/S – part B

Mix two components in adequate proportions in a mechanical or manual manner. It is recommended to place the composition in the vacuum chamber (30-60 mbar) in order to eliminate any entrapped air. During deaeration process which should not take more than 5 minutes the silicone mixture foams and expands to 5 times of initial volume and then returns to its previous volume. Wait then 2 minutes and pull the material out of the chamber. Pour the ready composition into element and wait until crosslinking. After complete crosslinking, the obtained composition has consistency of semi-liquid gel (Polsil® MV AB) or transparent silicone rubber (Polsil® MV AB/S).
