Technical Data Sheet
FUTUREWAY
®
EN-4S
Potting heat insulation adhesive
FUTUREWAY
®
EN-4S is a 2-component liquid silicone rubber which cures at room temperature. The silicone
system contains no solvents or plasticizers.
Features & Benefits
High flow behavior
Useful temperature range -50°C to +200 °C
Good tightness to aqueous media
Good UV resistance
Low water absorption
Good mechanical resistance
Good chemical resistance
Good low temperature flexibility
Excellent ultra high temperature heat insulation capability
Typical Applications
2-component liquid silicone rubber for potting
Processing
Processing generally takes place using 2-component mixing and metering
systems. The material must be homogenized by gentle stirring in the supply
vessels
The material surfaces must be kept clear of platinum catalyst poisons such as
sulfur, amine, phosphorus, chlorine and tin compounds
Flawless silicone curing must be confirmed in advance by testing
Small quantities of hydrogen are created during the reactive time
Curing
After mixing the A+B components, curing takes place at room temperature. A few
minutes at 50-80°C causes a tack free surface of the silicone and shortened
assembly time. If a low compression set is needed the gasket should be cured for
20-30 minutes at the maximum exposure temperature.
