Introduction
SS861 is the single component and non-sag type silicone sealant which is specially designed for the expansion joint, contraction joint and vertical joint of the airfield runway, highway, tunnel, bridge and other concrete roads. It is characterized by low modulus and good expansion & contraction recovery which can accommodate the displacement of the concrete joints. The accelerated weathering aging tests show that its excellent weatherproof aging property can completely resist the harsh tests of the high and low temperature as well as the strong ultraviolet radiation environment of the concrete road.

Adhesion Test:
SS861 road silicone sealant has excellent adhesion to the concrete. No primer is necessary. But since the variety of the configuration of the concrete and the different surface cleaning conditions, we cannot ensure that the sealant is applicable to all kinds of road concrete. Small scale of field adhesion test must be carried out before the large-scale application so as to propose reasonable plan and further to ensure the good adhesion.
