Tilebond 402 Epoxy Technical Data Sheet

TILEBOND 402
Flexible impact resistant epoxy adhesive
Description
Tilebond is a flexible, heat resistant epoxy adhesive for permanently bonding surfaces subject to
impact, vibration and deflection.
High Degree of Flexibility :- Impacts and vibration are absorbed and dissipated along the bond line.
This means the adhesive and tiles won't crack or be dislodged.
Toughness & Resilience :- The adhesive will recover to its normal state after shock loading and
forced deformation.
High Temperature Exposure :- Exposure to temperatures up to 150°C increases the adhesives
flexibility unlike conventional epoxy adhesives which become more rigid.
Adhesion :- An adhesion promoter increases the bond strength to a variety of substrates.
Tilebond has proven to be highly successful in bonding fusion cast high aluminia ceramic tiles for
protection against the abrasive effects of transporting fuel, coal and shale. It has proven track record
in both coal preparation plants and coal fired power stations.

Instructions for use
Surface Protection
Steel or concrete surfaces may need to be mechanically abraded and/or degreased to achieve a
clean sound substrate, free from loose rust, laitance, dust etc. Sandblasting, grinding or wire brushing
are acceptable methods of abrasive cleaning. New concrete surfaces should be first allowed to cure
for up to 14-28 days depending on ambient conditions. Tilebond may be applied to steel or concrete
which has a sound protective coating. A light grit-blast or emery paper treatment should then provide
an adequate mechanical key, but an adhesion test is always recommended.

Mixing and Application
The mixing ratio for base: hardener is 1:1 by volume (1.68:1 by weight). An automatic dispenser is
recommended to achieve accurate proportioning in large scale applications or for frequent small scale
use. The material should be mixed until a smooth uniform appearance is obtained. Application can
be via a notched trowel or palette knife to achieve the desired film thickness, which may vary
according to the conformity of the surface. The substrate temperature should be at least 3°C higher
than the dew point for given ambient temperature and humidity conditions, to prevent surface
condensation occurring. The application temperature should be in the range of 5°C – 40°C.
Material Compatibility
Since the adhesive is solvent free, wet and dry thickness will be equal, therefore 1 litre of mixed
material will cover 1 square meter at 1mm thickness, without allowing for wastage etc. Typical film
builds are in the range of 0.5mm to 5.0mm.
Cleaning
Suitable solvents are: cellulose thinners or acetone. Refer to solvent suppliers for safe handling
information.
