Dezo Injection-201

Flexible PUR-Injection resin for permanent watertight sealing

 

Product

Dezo Injection-201 is a very low viscous, flexible and solvent-free polyurethane

 

Description

injection resin. In contact with water, a uniform, closed and therefore watertight pore structure forms, which is elastic and flexible.

 

Uses                                          „   

Dezo  Injection-201 is used for permanent watertight sealing with some flexibility to absorb limited movement, in dry, damp or water-bearing cracks and joints in concrete, brickwork  and natural stone Dezo Injection-201 can be used for the injection of the Dezo  Injectoflex- System (non re-injectable!) For use in water-bearing cracks under hydrostatic pressure, preliminary injection with shall be made with Dezo Injection-101

 

Characteristics / Advantages

„    Permanently elastic, can absorb limited movements

„    No shrinkage in subsequent dry conditions

„    Due to its low viscosity it can penetrates into cracks >0.2 mm in width

„    Cured Dezo  Injection-201 is inert and chemically-resistant

„    Solvent-free, environmentally friendly, usable in ground water protection zones

„    In cold temperatures (< +10°C) Dezo Injection-201 can be accelerated using Dezo  Injection-AC20  Can be injected as a one           component system (when no accelerator is used)

System

Information

 

Application Details

 

Substrate Preparation  Surfaces of cavities and cracks need to be clean, free of loose particles, dust, oil and any other bond-breaking substances. Any dirt must be blown out by compressed air.

 

Application Conditions/ Limitations

 

Substrate Temperature       +5°C min. / +35°C max.

 

Ambient Temperature         +5°C min. / +35°C max.

 

Application

Instructions

 

Mixing Ratio            1 : 1 parts by volume

 

Mixing      -   Empty parts A and B into a mixing vessel and mix slowly and thoroughly for at least 2 min (max. 250 rpm) until homogeneous, observing the safety precautions. The containers are supplied according to the required mixing ratio of 1 : 1 parts by volume.

-   Partial quantities can be measured out into separate vessels. After mixing, pour the material into the pump’s feed container, stir briefly and apply within the pot life.

-   After mixing, pour the material into the pump’s feed container, stir briefly and use within the pot life.

If the substrate and/or ambient temperatures are < +10°C, Dezo Injection-AC20 can be added to accelerate the reaction time.

Application Method / Tools

 

The given data are laboratory parameters and may deviate depending on the object and conditions on site.

Text Box: weight of Sika®Use injection pumps suitable for single part products, such as Dezo  Injection Pump

EL-1, EL-2, Hand-1 or Hand-2.

 

 

Cleaning of Tools  Clean all tools and application equipment with Dezo .Colma-Cleaner to remove any polyurethane residue immediately after use. Do not leave Dezo .Colma-Cleaner in the injection pump. Hardened/cured material can only be removed mechanically.

 

Notes on Application / Limitations

The waterproofing process is divided into three phases:

 

Injection:

The time during which the injection material flows under pressure from the pump to the desired moisture ingress/water containing areas.

 

Induction:

The time from initial mixing until the reaction starts.

 

Reaction in contact with water:

The period during which the mix viscosity increases and foam formation takes place.

or Reaction in dry conditions:

The period during which the mix viscosity increases and the hardening process

(without foam formation) takes place

 

 

For water intrusions that can not be stopped with Dezo  Injection-201, the fast foaming PUR injection resin Dezo  Injection-101 can be injected until the water flow stops.
