Application Description

Liquid applied membranes provide a tough but flexible/elastomeric membrane with specific performance property requirements.  They are used extensively in the construction market segment and offer vapor, water and/or air resistance.

For this complex market, MCP offers emulsion polymers that allow the customer to formulate for all three types of liquid applied membranes (vapor, water or air resistive) and for all variations of formulations, elastomeric, cement containing, and blends with asphalt emulsions.

CARBOXYLATED STYRENE-BUTADIENE EMULSION

  • Polymer
  • Solids (%)
  • Viscosity (cps)
  • MFFT (°C)
  • BarrierPro® 4555
  • 50.0 - 52.0
  • 1000 max
  • 0
  • BarrierPro 4555 is a styrene-butadiene emulsion polymer of low stiffness. It dries to form a soft but tough film. Its softness makes it excellent for water proofing where films must remain flexible at below-freezing temperatures.

  • BarrierPro® 4550
  • 49.0 - 51.0
  • 900 max
  • +10
  • BarrierPro 4550 is a general purpose styrene-butadiene emulsion polymer of medium stiffness. It dries to form a flexible, tough film of high water resistance.

  • BarrierPro® 4559
  • 49.0 - 51.0
  • 100 - 900
  • +10
  • BarrierPro 4559 is a low odor, general purpose styrene-butadiene emulsion polymer of medium stiffness. It dries to form a flexible, tough film of high water resistance

  • BarrierPro® 4551
  • 52.5 - 54.5
  • 1000 max
  • +8
  • BarrierPro 4551 is a carboxylated styrene-butadiene emulsion with excellent strength properties, high resistance to liquid water and water vapor, high blush resistance and excellent adhesion to multiple construction substrates.

  • BarrierPro® 4545
  • 51.0 - 53.0
  • 200 - 1000
  • +8
  • BarrierPro 4545 is a styrene-butadiene emulsion polymer of medium to high stiffness. It dries to form a flexible, tough film of high water resistance.
