MasterSeal SL 189 - A
Ultra-low modulus silicone sealant for concrete to concrete / concrete to asphalt and asphalt to asphalt pavement joints
MasterSeal SL 189 is a high performance one
component, moisture curing, silicone
construction sealant. In properly designed and
constructed joints the product has been
formulated to offer ultra-low modulus, fuel and
UV resistant, elastomeric seal.
Asphaltic paving materials have low tensile
strengths. It is important to use an ultra-low
modulus material when sealing these substrates
to ensure minimal strain is placed on the
asphaltic joint face.
Where is MasterSeal SL 189 applied?
MasterSeal SL 189 has been developed
specifically for sealing dynamically moving joints
such as; expansion and control joints.
MasterSeal SL 189 can be used to seal
irregularly shaped and spalled joints.
MasterSeal SL 189 sealing sawcut openings
used to encapsulate and seal sensitized wiring
loops for control of traffic signals, traffic
counters, parking lot gates, ticket dispensers,
and other similar equipment. It is also excellent
for use in sealing light cans and electrical cable
used in airport runway lighting.
