SikaBond® TF Plus R is a 1-component, PU-based adhesive for the SikaMembran® facade membrane system, which combines high mechanical strength with the necessary elasticity to cope with high movements in facades. SikaBond® TF Plus R adheres very good to a wide range of substrates.  

  • EMICODE EC1PLUS , very low emission
  • Secure application with good sag resistance
  • Bonds well to concrete, aluminium (anodized or powder-coated), rigid U-PVC, timber and other standard construction materials
  • Application of adhesive to one side only (mostly to substrate)
  • Ensures levelling of substrate
  • No contact pressure necessary
  • Fast curing
  • Adjustment of membrane possible until 30 minutes after installation

Areas of Application

SikaBond® TF Plus R is used for bonding SikaMembran® facade membranes (e.g. SikaMembran® Universal, Outdoor, Outdoor plus, Strong, Eco Uni, Eco Out) behind curtain walling and rainscreen cladding. SikaBond® TF Plus R is also suitable to bond over plasterable membranes (e.g. SikaMembran® Uni-P, Outdoor-P) to concrete and brick wall in window installation.
This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

CURE MECHANISM

SikaBond® TF Plus R cures by reaction with atmospheric moisture. At low temperatures the water content of the air is generally lower and the curing reaction proceeds somewhat slower.

CHEMICAL RESISTANCE

Resistant to water, seawater, cement grout and water-dispersed detergents.

Application

Surface preparation

The substrate must be sound, homogeneous and no paint or other coatings must be present. It needs to be clean, dry and free from oils, grease, dust and loose or friable particles.
Surface treatment depends on the specific nature of the substrates and is important for a long lasting bond.
Treat non-porous surfaces with Sika® Aktivator-205. Clean porous surfaces by wire brush and / or vacuum cleaner. On porous substrates exposed frequently to water use Sika® Primer-210 or Sika® Primer-3 N. Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates.
Structured and metallic powder coatings has to be grinded with abrasive pad -very fine- and treated with Sika® Aktivator-205.

Application

SikaBond® TF Plus R can be processed between 5 °C and 40 °C but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and adhesive is between 15 °C and 25 °C. Until the adhesive is fully cured the substrate temperature must be in between 5 °C and 40 °C.
To avoid condensation on the surfaces, the temperature of the bonding substrates must be at least 3 °C higher than the dew point of the air.
The skin time is significantly shorter in hot and humid climate. The SikaMembran® must always be installed within half of the skin time. Never join bonding parts if the adhesive has built a skin.
SikaBond® TF Plus R can be processed with manual, pneumatic or electric driven piston guns.

 

Tooling and finishing

Tooling and application of SikaMembran® must be carried out within the skin time of the adhesive.
For detailed information about the application of SikaMembran® consult Product Data Sheet “SikaMembran System".

Removal

Uncured SikaBond® TF Plus R can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once cured, the material can only be removed mechanically.
Hands and exposed skin have to be washed immediately using hand wipes such as Sika® PowerClean wipes or a suitable industrial hand cleaner and water.

Do not use solvents on skin.

Application limits

Where two or more different reactive process materials are used, allow the first to cure completely before applying the next.
The compatibility of gaskets, backer rods, and other accessory materials with SikaBond® TF Plus R must be tested in advance.
Do not use SikaBond® TF Plus R on natural stone or as a glazing sealant.
Do not use on PTFE (Teflon), Polyethylene (PE), Polypropylene (PP), Polystyrene (PS) and bituminous substrates, natural rubber, EPDM rubber or on any building materials which might leach oils, plasticisers or solvents that could degrade the product.
Do not mix with or expose uncured SikaBond® TF Plus R to substances that may react with isocyanates, especially alcohols which are often components within e.g. thinners, solvents, cleaning agents and formwork releasing compounds. Such contact could interfere or prevent the cross linking curing reaction of the material.
