GAP FILLING EPOXY PASTE ADHESIVE FOR CIVIL ENGINEERING
MEGAPOXY RMF is specially formulated non-sag epoxy filling paste
and adhesive. This easy to use two-part epoxy product sets after mixing
with excellent properties ideally suited for the following applications.
Precast concrete articles
Bricks and ceramics
FILLING AND REPAIR
Concrete Pipes and Tanks
Concrete floors and stairs
Insitu formed concrete
Simple 1 : 1 mix ratio
Creamy texture, blends easily
Non sag on vertical surfaces
Adheres and cures under adverse conditions (cold and damp)
Good strength retention after prolonged immersion in water
Tensile and compressive strength superior to concrete
Very good chemical resistance
PART "A" PART "B"
Consistency Thixotropic paste Thixotropic paste
Colour White Black or Neutral
Flash Point Above 100°C Above 100°C
METALS Should be grit blasted to clean surface.
Mechanically abraded and degreased.
Wire brushing is not entirely satisfactory and gives
minimal adhesion only.
CONCRETE Should be free from grease and oil. If necessary, clean
industrial grade degreasing agent. Once clean, steps must
be taken to remove laitence; this is best done by using :
Acid etching - concentrated hydrochloric acid (muriatic
acid) 1:1 with water, and spreading 0.5 litre of this
mixture to each square metre. After the reaction has
ceased (about 10 minutes) the area is thoroughly washed
and scrubbed with a stiff bristled broom to remove loose
sand and allowed to dry for 24 hours.
PAINTED SURFACES :
Metals - a proprietary brand paint stripper should be used.
Concrete - the surface may be either flame cleaned or mechanically
Mixing Ratio : 1 part resin to 1 part hardener by volume
Mixing : Mix until uniform grey or white
Working life at 25°C : 10 minutes
Minimum application temperature :5°C
Minimum Cure Time : 2 hours at 25°C
Full Cure Time : 2days at 25°C
It is essential that the correct mixing ratio be used and that the Part "A"
and Part "B" are thoroughly mixed together before use. Inaccuracies
and poor mixing will result in lower physical properties of the cured
system and, if the error is sufficiently large, the system may not cure
satisfactorily and discolour on ageing.
