WACKER launches new products for fabric coatings
Wacker has developed two new condensed cross-linked silicone rubber products for fabric coatings, ELASTOSIL E 91 and ELASTOSIL E 92 N, typical applications for suspenders of nylon socks with a non-slip layer or rubber dots
for the soles of non-slip socks.
The newly launched ELASTOSIL E 91 and ELASTOSIL E 92 N are acetic acid cross-linked silicones that cure
under the action of moisture in the air.
At the same time, these two new products also use a new catalyst system, which does not contain organotin compounds.
Standart 100 Textile Eco-certification specifies
limit values for organotin compounds.
In addition, the two new products have good flow and are extremely easy to process
.
Fabrics are coated without changing operating habits or curing processes, and they cure at speeds similar to those of conventional
silicones.
The viscosity design of the new product allows it to wet the fabric surface well without penetrating the fabric mesh
.
ELASTOSIL E 91 and ELASTOSIL E 92 N are also different
.
ELASTOSIL E 92 N is more transparent and can be used in a wide range of colours
.
In addition, the processing characteristics of the two differ depending on the catalyst system: the catalyst used in ELASTOSIL E 91 withstands higher curing temperatures and is ideal for steam furnace processing; ELASTOSIL E 92 N rubber cures
quickly at room temperature.
