Ultimate Chemical Resistant Coating

PRODUCT SPECIFICATIONS:

Ultimate Chemical Resistant Coating was designed
as the ultimate chemical resistant
high build coating. HJ-209 has increased resistance to
chemicals and higher strength but requires consideration
for a very short pot life and fast cure. HJ-209 is based on
high performance resin technology with a fast
acting cycloaliphatic amine, and maintains solventless
character to meet the highest standards of chemical
resistance and corrosion protection achievable.
Primarily a barrier coating or lining suited to treatment of
steel, concrete and brick in applications where acids,
alkalis, organic solvents, or a number of chemicals in
process give rise to problematic conditions.
functionality and high cross linking density is the
key stone of HJ-209 technology which also contains a
unique fill that offers high resistance to erosion and
abrasion without compromising chemical resistance.

SURFACE PREPARATION
Methods for substrate preparation may include chemical
means such as washing & etching, high pressure water
blasting, or traditional abrasive blasting techniques .
Caution should be maintained in selecting a technique
that provides satisfactory anchor for the lining.
Specialist advice is available from Peerless Industrial
Systems to ensure the correct preparation procedure is
employed for specific applications.
APPLICATION
Mixing of product should be carried out using slow speed
mixers and completed by adding to the part “A”, the part
“B”. Ensure the mix is homogeneous and free from lumps.
Avoid air entrainment.
HJ-209 can be applied either by airless spray, brush or
roller. Since it does not contain solvents, application by
spray allows the application of high film thicknesses in single
coats, and ensures that all material purchased actually
contributes to the final DFT. HJ-209 is a higher viscosity
than conventional solvent containing coatings and application
may require more specialised practices but is generally
compensated for by the speed of application and need to
apply fewer coats.
Epigen Diluent maybe added to HJ-209 to control viscosity
under some circumstances. Avoid excessive additions and
do not add Diluent in confined spaces or near naked flame.
Do not add thinners to extend pot life.
In concrete correction applications, blow holes, cracks, or
significant damage maybe faired by mixing 1 part HJ-209
with 1.5parts 30/50 sand and applying the paste to the
damaged areas. This practice should be employed after
the first coat application when the extent of degradation
becomes apparent and before second coat application.
CHEMICAL RESISTANCE
Tested at 21oC. Samples cured for 10 days at 25oC.
Curing at elevated temperatures will improve chemical
resistance.

This information is supplied as an indicative reference only.
Caution should be used where direct comparisons are to be made.
Note : Under acidic conditions, HJ-209 has been designed to
change colour allowing steps to be taken in cleaning up
spills or as a warning to beware.
CURE
Variations in cure may arise due to the amount of material
being applied, the thickness of material being applied, the
surface temperature, and the product temperature. The
cure may be increased by heating product or by leaving
mixed material stand for 15 minutes before use. The cure
may be decreased by cooling the product before mixing.
