BETTOSEAL PU - B 2K

BETTOSEAL PU - B 2K

Polyurethane - Bitumen Based, Two Component, Liquid Waterproofing Membrane

MATERIAL DESCRIPTION

BETTOSEAL PU - B 2K is a bitumen enriched; polyurethane based, two component, fast curing, elastic, cold applied, elastic liquid membrane for waterproofing and protection purposes. It adheres strongly to many surfaces and forms a highly elastic film layer.

A Comp. 20 Kg + B Comp. 20 Kg = 40 Kg Set Tin
AREAS OF USE 
• In subsoil foundation and curtain concretes,
• In terrace insulation above the parking lot,
• Bridge platforms,
• Cut-and-cover tunnels,
• Retaining walls.
• Used on surfaces such as EPDM-Bituminous membranes and
asphalt.

APPLICATION METHOD
After mixing BETTOSEAL PU - B 2K as recommended above, it should
be poured onto the primed surface and spread with a roller, brush or
toothed trowel until the entire surface is covered. After 12-24 hours (do
not wait more than 48-78 hours at the latest), another coat of
BETTOSEAL PU - B 2K should be applied. If desired, a third coat of
BETTOSEAL PU - B 2K can be applied after the waiting time has elapsed.
If BETTOSEAL PU - B 2K is to be covered with ceramic tiles, saturate
with baked, dry silica sand (size 0,4- 0,8mm) while the last coat of
waterproofing material is wet. The silica sand will form an adhesion
bridge over the waterproofing. For best results, the temperature during
application and curing should be between +8°C - +35°C. Low
temperatures delay curing, while high temperatures accelerate it. High
humidity may affect setting.

ADVANTAGES
• Fast curing.
• Can be applied in thick coats, does not form bubbles.
• After opening the package, the unmixed components can be
stored for later use.
• Its crack bridging properties are excellent due to its low modulus.
• Exhibits effective resistance to chemicals.
• It adheres perfectly to any surface, primed or unprimed.
• Although it does not need to be thinned, it can be thinned
with polyurethane thinner according to the conditions
• Its thermal resistance is excellent, the product never softens.
• Maximum use temperature is 80°C, maximum shock temperature is
200°C.
• Resistant to cold, the film retains its elasticity up to -40 °C
• Excellent mechanical properties.
• It has high elongation, tensile, tear and abrasion resistance.
• Plant root resistance.
• It functions effectively as a water vapor barrier.
• It can also be applied as joint filling material.
• The 1/1 volume of the components facilitates the mixing process
