THERMAL
PROPERTIES
Grouting may be carried .out at ambient temperatures between
69 C and 30s C.
The cured grout is completely resistant to frost and extreme
sub-zero temperatures. Continuous exposure to load at temperatures above 45s C
should
be avoided.
Huntsman should be contacted for advice prior to specification
if higher temperatures are anticipated.
INSTRUCTIONS FOR USE
PREPARATION
The
concrete structure must be solid and strong enough for the intended load.
Optimum
performance of Araldite Anchorbond requires the formation of a mechanical
fixing through chemical hardening of the grout. Holes must therefore provide a
mechanical key.
Drilled holes should be prepared by a rotary percussive drill
with air or water flush.
Diamond drilled holes must be under-reamed.
Cast
in holes must be of inverse dovetail configuration. If parallel sided holes are
cast they should be rough to provide adequate keying.
However formed, the hole
must be clean and free from dust, grease or dirt.
All bars should be degreased
and all flakey rust removed.
.MIXING
Mechanical mixing of
resin based materials is preferred whenever possible.
In order to avoid trapping
air in the material, mixers running at less than 400 rpm are recommended. For
small quantities, manual mixing is acceptable.
PLACING
Araldite
Anchorbond is supplied in 3 pre-weighed packs of exact proportions. No other materials
should be added. Stir the contents of each tin
thoroughly.
Pour the entire
contents of the hardener into the resin and mix until uniform. Slowly add the
graded filler and mix until fully blended.
Araldite Anchorbond P may
then be poured into the hole.
Araldite Anchorbond T should be pumped
into the hole starting from its deepest part and working backwards to avoid trapping
any air. Due to its
thixotropic nature, it will not run out even, from overhead
cavities. The steel bar should then be worked into the grout and fixed in place
until
hardening is complete. Ensure placing and fixing is completed within
the pot life of the mixed batch.
CURING
Allow the grout to fully
harden before applying load.
STORAGE
Shelf life of 12 months
minimum if stored below 25s C.
CAUTION
Keep uncured epoxy materials
away from the mouth, food or drink.
Do not use empty tins to store food even
if they appear to have been cleaned. Always wear gloves or barrier cream when
handling uncured epoxy materials. Clean any splashes or smears from the skin immediately
using warm water and soap. Avoid inhaling vapour. Do not use below 59 C.
