MasterSeal 878 - Rapid curing, chemical resistant, elastomeric waterproofing membrane
How does MasterSeal 878 work ?
MasterSeal 878 is a solvent free, two component, high performance polyurea based waterproofing membrane, with high resistance to common chemicals. Using a specially designed spraying machine, the two components are pre-heated and spray applied, to a rapid curing, elastomeric, waterproofing membrane
MasterSeal 878 is recommended for water- proofing of large structures exposed to aggressive waters, containing potable water and other containment structures..
Typical application areas include:
Water containment areas.（potable and contaminated）
Primary & Secondary containment tanks
Waste water treatment tanks
Protection & waterproofing of infrastructures
What are the Features & Benefits of MasterSeal 878 ?
Fast reacting - Rapid installation. Does not run when applied on vertical surfaces
Seamless - No risk of leaky seams and laps.
Spray applied - Fast installation on large surfaces; easy application on complex details.
Fully bonded - Eliminates water collection behind membrane even if punctured.
High tensile strength - Excellent ability to accept movements without rupturing.
Elastomeric - Excellent crack-bridging ability.
High tear resistance - Minimized risk of damage to membrane in service.
Low Tg of -20˚C - Remains elastomeric at very low temperatures. Performance unaffected in below freezing conditions.
Solvent-free - Improved safety
Potable water contact approved – suitable for tanks containing drinking water.
