PR1910 is silicone sealant designed for use in a temperature range of – 75°C to + 375 °C with outstanding resistance to aging.

PR 1910 is a two-part, silicone, liquid polymer compound. The mixed compound is a thixotropic paste which can be readily applied by spatula or extrusion gun. It does not flow from vertical or overhead surfaces. Cure takes place at room temperature and without shrinkage, to form a resilient sealant possessing excellent resistance against aging, ozone and humidity. With primer JFP 7010 it gives excellent adhesion to aluminium, magnesium, titanium, steel, and numerous other materials. After curing at ambient  temperature it will resist 150°C. With heat treatment it will resist 375 °C and for short periods even temperature between 1100°C and 2800°C.
