ISOPOLANT PU-B FC
ISOPOLANT PU-B FC
One-component, polyurethane-bitumen FAST CURING liquid membrane for waterproofing
One-component, polyurethane-bitumen fast curing liquid membrane. Despite rapid curing, the product does not show bubbles during the polymerization process, even at high atmospheric temperatures and humidity, while exhibiting excellent adhesion to most types of surfaces.
The membrane is based and on pure elastomeric hydrophobic polyurethane resin expanded by chemically polymerized pure bitumen.

Application area
• Foundations
• Underground walls
• Under tiles, for example on balconies, terraces and wet rooms
- not recommended to use in the places, exposed to direct UV radiation.
Features and benefits
- Easy to apply on vertical surfaces and complex shapes without smudges with minimal bubble formation
- Very fast cure even at low temperatures and low humidity
- Excellent practical adhesion to any type of surface, with or without special primers
- Excellent heat resistance, the product never becomes soft. Maximum operating temperature 80°C
- Resistance to cold: the membrane remains flexible even at -30°С
- Excellent mechanical properties, high elongation, tensile and tensile strength, high abrasion resistance
- Effective moisture barrier
Application procedure
1
Requirements for a concrete substrate (standard):
• Hardness of concrete: R28 = 15Mpa.
• Concrete humidity: W <10%.
• Temperature: 5-35o C.
• Relative humidity: <85%.
The substrate must be dry, chemically neutral, even, strong - without cracks and damage, clean - without dust, rust or flaking particles. Seal cracks, damage, holes must be coated with suitable material. Traces of contamination from oil, oil substances or chemicals must be removed.

Immediately prior to use, the content buckets must be carefully mixed using a low speed mixer (up to 300 r/min) to a homogeneous mass. Prolonged storage may cause slight dreg and/or separation of products, that are to be re-homogenized. It is necessary to carry out mixing very carefully, especially on the walls and bottom of the bucket, until the mixture becomes completely homogeneous, while preventing air from entering the fluid.

Apply with a brush, roller or trowel in one layer, flow rate 2.0 kg/m2.
General information
25 kg, 5kg
It can be stored for 12 months minimum in the original unopened buckets in dry places at temperatures between 5° C to 25° C. Once opened, use as soon as possible.
Contains volatile flammable solvents. Apply in well-ventilated, no smoking areas, away from naked flames. Indoors, use ventilators and carbon active masks. The MSDS (Material Safety Data Sheet) is available on request.
