Polyurethane - Bitumen Based, Two Component, Liquid Waterproofing Material - PU-B 2K

Description

PU-B 2K is a polyurethane-bitumen based, two component, fast curing, super elastic liquid waterproofing and coating material.

Fields of Application

Excellent adhesion on different kind of surfaces, such as concrete, mosaic, metal, galvanized, asphalt etc.
On basements, foundations, bridges platforms, irrigation channels,
On underground construction,
On old bituminous or EPDM membranes,
Polyurethane insulation boards,
Balconies, terrace, flower pots and roof-top gardens,
Outer surface of non-potable water tanks,

Features and Benefits

Fast curing.
Has high adhesion performance on wide variety of surfaces.
Retains elasticity even at low temperature. Elastic properties prevent the cracks on the surfaces that it is applied.
Resistant to very high and low temperatures.
Excellent mechanical resistance, crack bridging performance, tensile and tear strength.
Excellent chemical resistance.

Application Procedure

Preparation of Substrate

The surface should be washed and clean of all contaminant such as oil, grease, wax etc. Loose particles, cement laitance, release agents, cured membrane must be removed from the surface. Surface must be completely dry. Humidity on surface must be maximum 4%. For on fresh concrete application, needed minimum 28 days for curing concrete. Surface must be primed with PU 101 A or EPOX PR 100.

Application Method

A ve B components must be mixed under low stir mixer until homogenous mixture is obtained. Material is applied by a brush, roller or spatula. Mixed material pot life is 30-45 minutes. At least two coat application is recommended
