Silopren LSR 2540 is a two-component liquid silicone rubber especially developed for the coating of textiles and glassfibre fabrics.

Key Features and Benefits
Vulcanisates consisting of Silopren LSR 2540 are distinguished by the following properties:

low viscosity

excellent thermal stability

high stability and flexibility at low temperatures

good rubber-like properties

long service life at dynamic stress

high stability to ozone and ultraviolet light

outstanding resistance to ageing

excellent dielectric behaviour over a wide range of temperatures

not readily combustible, does not melt or drip

easy pigmentable with the LSR Colour Pastes

Potential Applications
Because of the outstanding properties Silopren LSR 2540 is particularly suitable for the following applications: textile coating for protective suits or conveyor belts, coating of glasfibre fabric sleeves, coating of fabrics for compensators, tents and other technical applications s.o.
