Fixobond PU

INTRODUCTION

FIXOBOND PU is a highly modified, two-component polyurethane based high impact thin adhesive with high elasticity and no vertical slip. FIXOBOND PU is an excellent multi-purpose adhesive providing exceptional bond strength to a wide variety of substrates; concrete, glass, plastic, wood, metal, etc. This highly exible adhesive also provides excellent peel strength.

 

RECOMMENDED APPLICATIONS

Interior or Exterior
vertical and horizontal surface
Fixing for ceramic tile, vitrified tile, natural stone, mosaic
Fixing for wooden, metal tiles on various surface

COVERAGE

Approx. 2 - 4 kg/ m². This coverage is based on application by notched trowel onto a smooth surface in optimum conditions. Factors like surface porosity, temperature and application method can alter consumption.

PACKAGING

FIXOBOND PU is available in packages of 5 Kg (Part A 4.7 Kg & Part B 0.30 Kg ) in pre-determined mixing proportion by weight. The container of component 2 is built in the container of component 1.

SHELF LIFE

9 months from production date, if stored in original, unopened packaging in places protected from moisture, sun exposure and frost.

 

APPLICATION PROCEDURE

SURFACE PREPARATION

The substrate must be clean, dry, sound and free of all contamination such as dirt, oil, grease, and coatings etc. which hinder adhesion.
Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/ or vacuum.

MIXING

FIXOBOND PU consists of two parts and the proportions for the mix are ready to use. Pour the small container of part B in the large pail of part A and stir thoroughly with a variable speed mixer until a homogeneous and smooth consistency is obtained. The complete contents of both parts of the adhesive must be used at once. Improper mixing may result in a poor bond. Using a variable speed mixer should not take longer than 2 minutes to mix the two parts to a creamy texture. Over mixing will cause the catalyst to set up too fast, thus reducing pot life and entrapping air which may reduce bond performance. The adhesive has to be applied immediately after mixing, otherwise it will thicken and be much harder to trowel. The flooring must be installed while the adhesive is wet. The mix must be used within 45 minutes

APPLICATION METHOD

  1. Use the recommended notched trowel with sufficient depth to ensure that at least 80-90% of the adhesive transfers to the material backing.
  2. Do not spread more adhesive than can be covered with material within 30 minutes. (Note: floor and room temperatures directly affects setting time: The warmer it gets, the faster it sets).
  3. Install the flooring material onto the fresh adhesive.
  4. Push out air using the rubber hammer and press the tiles.
  5. Adhesive setting time will depend mainly on the temperature of the substrate, which are subject to increase in moisture or which are not perfectly dry.
  6. Do not lay on substrates subject to moisture rising or which are not perfectly dry.
  7. Cleaning or removal of adhesive must be done with solvent/thinner while the adhesive is still wet.

CURING

Optimum performance level is reached after 24 hours of curing.

* Kindly follow the required health and safety precautionary measures. (Refer our Safety Data Sheet for more details)
