Application

Adhesive is designed for indoor and outdoor ultrastrong fixation of chemical resistant tile, for protection of the building structures in premises of different purposes (including food processing without direct contact with food) and places where high demands are placed on resistance to mechanical loads, abrasive wear, aggressive agents exposure with pH level from 3,6 up to 14 and hygiene.

Properties

  • Application temperature from +5º С;
  • Odourless;
  • Polymer achieves its strength development very fast at earlier hardening stages and allows faster facility commission and this is extremely urgent for operating productions;
  • Surface is ready to use for pedestrian load in 8 hours after application, full mechanical and chemical load is possible in 3 days (at the temperature of 20°С inside the premise);  
  • Has high resistance to the exposure of the majority of chemical agents in various concentrations with pH level from 3,6 up to 14: mineral acids in low and average concentrations (30-50 %), organic acids in low concentrations (up to 15 %), alkalis solutions (up to 50 %), water, oils, fats, oil products, and some types of solvents (see chemical resistance list);
  • High adhesive composition plasticity after components mixture;
  • Minimal shrinkage (dry residue after resin polymerization is 98 %) and lack of shrinkage cracking;
  • Water and frost resistance, high bioproofness to fungal infections;
  • High resistance to abrasive wear (shore hardness D - 77 s.u.), mechanical strength (compressive strength 50 MPa, tensile strength 36,5 MPa) and increased adhesion to different types of substrate, single-piece articles made from different types of ceramic (including chemical resistant and fireclay  tile), porcelain stoneware, mosaic, natural stone, fused basalt and steel.

SURFACE PREPARATION

All factors preventing proper adhesion shall be thoroughly removed: dust, moving particles, scales, grease and oil stains. It must have mechanical strength and have sufficient bearing capacity. Residual moisture of concrete substrate on the depth up to 20 mm must not exceed 10 %. This moisture is obtained after 28 days since concrete base/ screed has been laid in naturally wet hardening conditions. In case of concrete surface reinforcement, decrease capillary leak of water and binding free water (if residual moisture is more than 10 %) the usage of epoxy bottoms is recommended. For these purposes epoxy water emulsion based bottom Primer EP 01 (can be applied to dry and wet substrates) will be suitable. If technological break between bottom application and further adhesive layer application lasts more than 12-24 hours (depending on the temperature), it is essential to sprinkle calcined quartz sand fr. 0,3-,07 mm on the substrate immediately after priming and spread it evenly over the surface. After bottom hardening extra amounts of quartz sand are swept with brush.

 

MIXTURE PREPARATION

Tile adhesive preparation is done by thoroughly components mixing on the worksite. For doing this, it is essential to open the bucket with ingredients B (low-viscosity liquid) and pour it into the bucket with ingredients A (thick paste).These ingredients can be mixed directly into the bucket with a mechanical mixer or low-speed (300-400 rpm) electric drill equipped with a special mixing head. Mixing shall be done for not less than 2 minutes to form a homogeneous mixture without stripes and lumps. Special attention shall be paid to mixing the composition near the walls and bottom of the bucket. Manual mixing of adhesive components is not recommended. Freshly-prepared tile adhesive composition must have elastic, homogeneous, pasty consistence, resistant to subsidence. When mixing paste with hardener it is essential to strictly keep proportions of the components written in product passport and in the manual.

Upward and downward variations from stated proportions lead to the loss of hardened composition technical properties!

 

CONSUMPTION

Tile adhesive Himflex-KX consumption depends on applied type of lining products and according to reference data with recommended layer thickness of 2,5…3 mm is approximately 4…4,8 kg/1 m² tile (excluding decorative framing), 2,8-3,5 kg using comb fitting of 6 mm and it can also be strictly calculated using the following formula:

msc = 1650 × (V layer +V tile joints), kg

where msc – specific consumption for 1 m²;

1650 – specific weight, kg/m³

Vlayer – volume of the layer beneath the tile, m³

Vtile joints – tile adhesive volume in tile joints between lining products, m³

 

SURFACE USE (at the air temperature from +18º up to +25º С)

  • Surface is ready to use for pedestrian load in these hardening conditions in 8 hours;
  • Surface is ready to use for full mechanical and chemical load in 3 days;
  • In case of lower temperatures the possibility of surface use can be delayed up to 2 days for pedestrian load and 7 days for chemical and full mechanical loads. 

 

MANUALS

  • Not recommended for construction (compensating) joints filling (for this purpose the usage of chemical resistant sealant (mastic) Himflex EPU 510 is more preferable);
  • Clean tile surface before the composition hardened (see Application unit)
  • Ready-mixed adhesive shall be applied within 30 minutes.;
  • Do not expose Himflex-KX to chemical load earlier than in 3-4 days after application (depending on air temperature in the premises where works were carried out).

 

SAFETY REGULATIONS

  • Wear protective gloves and glasses while working with composition;
  • If skin contact occurs, the area should be immediately and thoroughly washed with water;
  • If exposed to eyes, eyes should be immediately and thoroughly flushed with water and seek medical attention immediately.

 

TRANSPORTATION AND STORAGE

  • Modified epoxy resin included in ingredients A is not affected by crystallization that allows storage and transportation even at below-zero temperatures;
  • Tile adhesive components (Ingredients A and B) shall be stored in sealed containers in covered storage rooms (in unheated is also possible);
  • In case of tile adhesive transportation and storage at the temperature lower than 0º С, unpacking of containers shall be made not earlier than in 24 hours after their conditioning at the temperature not lower than 20º С.
