BAIYUN pavement/road self-leveling Silicone Sealant SS860

SS860 Road Silicone Sealant
Brief Introduction
SS860 is the single component and self-leveling 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.
1. Products Properties
 Ease of application: self-leveling and no need finishing;
 No primer: neutral curing, chemically compatible with the concrete, firm chemical
adhesion to the concrete, normally it is not necessary to apply the primer;
 Long service life: excellent long-term weather proof aging properties; it will not be
damaged due to the influence of sunlight, rain, snow, ultraviolet radiation and ozone;
outstanding high and low temperature resistance; after curing, the cured silicone sealant
bar will not get hardened or brittle obviously under -40°C and still keep good elasticity; it
will not flow or degrade under +150°C;
 High movement capability: the sealant will be displaced freely with the expansion,
contraction and shearing of the concrete joints. But the sealant itself will not be damaged.
 Low modulus: when the sealant is deformed negatively, it will produce appropriately low
stress to act on the concrete substrate to make sure that the surface layer of the concrete is
not damaged.
 High elasticity and high recovery capability: the sealant can move repeatedly for many
times with the movement of joints. It can respond to and recover quickly. There is only
slight permanent deformation.

2. Main Application
 Used for filling and sealing the joint of the airfield runway and the highway, which can
resist large displacement;
 Used for filling and sealing the joint of other concrete roads;
 Used for the sealing of the subway, tunnel and bridges etc. projects.
