SS-1801 Product Description
Download PDF
SS-1801 is a fast curing silicone RTV adhesive rubber developed for radiator
sealing applications that require fast development of physical properties
and excellent adhesion. SS-1801 is a two part, 1:1 mix ratio silicone that
when mixed and applied to the substrate allows handling of the coated radiator
assembly within minutes. When cured the elastomer resists weathering, ozone,
moisture, UV and high temperatures. SS-1801 works well in static mix dispensing
equipment.

Mixing Instructions
The preferred method of mixing and application of SS-1801 is through a static
mixer at a 1:1 mix ratio by volume. The substrates should be held in place
for 10 minutes while the adhesive is curing.
Depth of cure vs time
Very firm deep section cures are formed in 15 minutes. Ultimate cured properties
are found in 24 hours.
Packaging
SS-1801 is available in 18 lb. kits, 90 lb. kits and 1000 lb. kits. This product
is also available in customer defined packaging sizes, upon request.
