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

Recommended Uses:

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.
