PRODUCT DESCRIPTION
Flex-Tec HV is a two component epoxy material designed specifically
for strength and flexibility. Engineered to move with the natural
expansion and contraction of various natural and synthetic
materials, Flex-Ease offers outstanding long-term performance.
Excellent modeling and tooling properties make Flex-Ease the ideal
choice for the professional or casual user.
Flex-Tec HV can be used on both vertical and horizontal surfaces.
Common applications are on exterior column bases, window sills and
sashes, and architectural wood ornaments. It is also suitable for
various manufacturing uses, the repair of natural wood imperfections
such as knots or checks, and the sealing of end-grain. Flex-Tec HV
is ideal for synthetic materials such as cellular PVC trim boards
and fiberglass.

APPLICATION LIMITATIONS |
|
|
|
(A) Do not apply over damp or contaminated/decayed surfaces.
(B) Designed to be used in concert with
Prime-A-Trate Flexible Cell bonding primer.
(C) Always apply varnish or paint after completing
the repair.
|
|
|
COLOR
Controlled mixing system turns amber after proper blending. Staining
can be achieved by adding dry pigment during the mixing process. Gel
stains can be used after curing.

PACKAGING
Flex-Tec HV is available in 450 ml dual cartridge dispensing system
using a heavy or Iight duty dispensing gun. 150 ml single cartridge
fits into a standard caulk gun and dispenses both A & B components.
Both dispensing systems are re-sealable.
|
|
|
MIXING
A disposable static mixing nozzle blends the resin
and hardener automatically and thoroughly to
facilitate proper dispensing. The automatic proportioning in the mixing nozzle assures precise,
consistent formulation. Material can also be
dispensed on to a flat surface and mixed by hand
using a putty knife.
|
|
|
WORKING TEMPERATURES
45 to 95 degrees Fahrenheit. Avoid working in direct sun light.
Curing time will be extended in temperatures below 45 degrees. (See
graph below.)

|
|
TOOLING
The unique modeling characteristics of Flex-Tec HV allows for both
vertical and horizontal applications without the requirement for
“dams” or molds to contain the material while curing. In most cases,
a simple putty knife can properly position the material to desired
shape. After mixing, Flex-Tec HV has an open time of 20 to 30
minutes. After a curing time of 16 hours, Flex-Tec HV can be sanded,
chiseled or drilled. Shrinkage during curing is less than 1%.
|
|
|
SAFETY AND HANDLING
Flex-Tec HV contains no VOCs. Avoid direct
contact with skin. Do not take internally. Consult
Material Safety Data Sheets for complete information.
|
|
|
CLEANING
Immediately remove all excess material from adjacent areas. Properly
mask all adjacent porous surfaces to avoid penetration. For skin
contact, wash with soap and water, household vinegar or citrus oil.
|
|
|
SHELF LIFE
3 years when stored in unopened, original container.
2 years once opened.
Store in cool, dry area.

WARRANTY
All recommendations, statements and technical data
contained herein are based an tests we believe to be
reliable and correct, but accuracy and completeness
of said tests are not guaranteed and are not to be
construed as a warranty, either expressed or implied.
User shall rely on his own information and tests to
determine suitability of the product for intended
use, and user assumes all risk and liability resulting
from the use of the product. Manufacturer and it’s
representatives sole responsibility shall be to replace
that portion of the product of the manufacturer which
proves to be defective. Manufacturer shall not be
liable to the buyer or any third party for injury, loss, or
damage directly or indirectly resulting from the use
of, or inability to use the product. Recommendations
or statements other than those contained in a written
agreement signed by an officer of the manufacturer
shall not be binding upon the manufacturer.
|
|
|
STRUCTURAL APPLICATIONS
Due to the high flexural modulus of the Advanced
Repair Technology’s repair products, we recommend
consulting a structural engineer to design a specific
load bearing recommendation.
|
|
|
PRODUCT REVERSIBILITY
For conservation projects that require the products
specified to be “reversible” in nature, Flex-Tec HV can be fully removed at any time using
a
Methylene-Chloride based paint stripping compound.
|
|
|
AGE CURING PROPERTIES
Flex-Tec HV is formulated with age curing inhibitors.
ACI’S block continued cross-linking common in
flexible epoxy systems. ACI’S prohibit Flex-Tec HV
from becoming brittle over time, protecting the
property of flexural strength (ASTM-D-790) |
