Ester Morter.(VE) :- |
° |
INTRODUCTION:
Vinyl Ester Mortar is used in the construction of floors,
sumps, trenches, tanks, vessels and bleach towers in
chemical processing, food and beverage plants, dairies,
laboratories, textile, steel and pulp& paper mills.
VE has excellent resistance to oxidizing bleach
solutions, mineral and organic acids, alkaline solutions
and some organic solvents. When used with chemical resistant
masonry units and the proper membrane VE will
protect concrete and steel sub base from chemical attacks
and physical abuse. VE is silica filled vinyl
ester mortar supplied in two parts – powder &
liquid – which must be mixed together in the proper
proportions (1:5.5 PBW) prior to use.

CHARACTERISTICS:
Resistant to strong oxidizing agents, acids, alkalis and
bleaches and solvents. Low absorption and shrinkage.
High bond, tensile and compressive strengths.
Rapidly develops physical properties… initial set time
is
one hour at room temperature.

Physical properties were determined on specimens
prepared under laboratory conditions using applicable
procedures. Actual field conditions may very and yield
different results; therefore, data are subject to reasonable
deviation. Data should not be used for specification
purpose.

SURFACE
PREPARATION:
All surfaces in contact with VE should be clean,
and free of dust, dirt, grease, oil, and other contaminants.
Surface prep should be in accordance with membrane
requirements.
|
| ° |
APPLICATION:
Empty correct proportion of liquid into a clean mixing
vessel. Gradually add measured amount of powder while
mixing continuously with a trowel, By hand or
mechanical mixer until mortar is uniformly blended to a
workable consistency. After mixing, spread mortar in a
thin layer in a mortar pan to ensure maximum working
time of 25 minutes at 35 * C. Recommended mix ratio by
weight, is Part A (Resin) 1 PBW to Part B (Filler) 5.5
PBW Material, which has begun to set, cannot be
retempered and must be discarded. Never add liquid or
other materials to mixed material or any component part.

CHEMICAL RESISTANCE:
Resistant tng oxidizing agents, acids, alkalis and
bleaches and solventso stro.

INSTALATION:
Trowel an average 1/8” thick bed joint of VE
directly on top of membrane or preceding course of
brickwork. Apply the mortar by buttering on side and one
head join of each masonry unit. Set the masonry units in
place and position by tapping to form an average 1/8” wide
vertical joint.
|
| ° |
FINISHING:
Strike extruded mortar off the face of the masonry unit
with a trowel. For floors where appearance is a factor,
waxed face units are recommended.
When waxed units are used, wait until VE
mortar has achieved full cure (24 hours at 35* C) and
clean face of masonry units using 60-psi (minimum)
steam pressure at the nozzle.

| ° |
CLEAN-UP:
All equipment should be cleaned with acetone or MEK
before MOPRO-VE cures. If removal is required after
cure, consult CHEMIPROTECT ENGINEERS for
recommendations. |
| ° |
SETTING/CURING:
VE is self-hardening due to a chemical reaction,
which occurs when the powder and liquid are mixed
together. An initial set occurs in one (1) hour at 35* C
-
the material is ready for service after twenty-four hours
at
35o C.

| ° |
SELF-LIFE:
VE powder has self-life of 3 months and liquid
has self-life of one (1) months, when stored in unopened,
tightly sealed container/bags in cool, dry place at 35o C. |
