SURFACE PREPARATION:
Abrade and clean surfaces before bonding. For best results, a chemical wipe of surfaces with a clean solvent (e.g. Acetone) works best
to remove grease, dirt, or dust.
DIRECTIONS FOR CARTRIDGE USE:
Place cartridge into the dispense gun. Before attaching the mix tip, dispense a small amount of adhesive to ensure proper
flow on both sides. If there is a restriction, use a pointed object to clear any blockage. Once blockage is cleared, dispense a
small amount to verify flow.
Attach mix tip. Begin pumping the adhesive through the mix tip. It is advisable to dispense a small waste shot of material to
ensure both A & B are mixed properly.
When finished dispensing, leave the mix tip attached. Adhesive in the tip will cure, creating its own seal for storage should
there be remaining adhesive in cartridge.
Remove used mix tip when using cartridge again. Repeat steps above to dispense more adhesive.
COLOR VARIATIONS:
The color of the base material may vary slightly from batch to batch due to raw ingredients. Color variations will not affect the
cured physical properties. Exposing the material to various conditions such as heat and UV light will alter the color of the cured
system. Color stability is not guaranteed. This product can be pigmented, but you may see more color shift when using lighter
pigments.
STORAGE:
Store ambient temperatures, 65-80 F (18-27 C). Unopened containers will have a shelf life of 3 months from date of shipment when
properly stored at recommended temperatures. Purge opened containers with dry nitrogen before re-sealing.
PACKAGING Part A Part B
50 ml Dual Cartridge 1 oz. 0.9 oz.
SAFETY PRECAUTIONS:
Use in a well-ventilated area. Avoid contact with skin using protective gloves and protective clothing. Repeated or prolonged contact
on the skin may cause an allergic reaction. Eye protection is extremely important. Always use approved safety glasses or goggles
when handling this product.
IF CONTACT OCCURS:
Skin: Immediately wash with soap and water. Remove contaminated clothing and launder before reuse. It is not recommended
to remove resin from skin with solvents. Solvents only increase contact and dry skin. Seek qualified medical attention
if allergic reactions occur.
Eyes: Immediately flush with water for at least 15 minutes. Call a physician.

DESCRIPTION
Sikaflex -291 is a non-sag 1-component poly-
urethane sealant specifically developed for the
marine market, which cures on exposure to at-
mospheric moisture.
PRODUCT BENEFITS
Bonds well to a wide variety of substrates
Good aging and weathering resistance
Elastic
Low odor
Non-corrosive
Can be over painted
Can be sanded
Listed under NSF Proprietary Substances
and Nonfood Compounds (black and white)
AREAS OF APPLICATION
Sikaflex -291 is a multipurpose product for use
in marine constructions. It is suitable to make
elastic, vibration-resistant joint seals, and can
also be used for a variety of interior sealing ap-
plications. Sikaflex -291 bonds well to the ma-
terials commonly used in marine construction
like wood, metals, metal primers and paint
coatings (2-C systems), ceramic materials and
plastics (GRP, etc.). Sikaflex -291 must not be
used to seal plastics that are prone to stress
cracking (e.g. Plexiglas, Polycarbonate, etc.).
Once cured, Sikaflex -291 can easily be sanded
as required.
This product is suitable for experienced profes-
sional users only. Test with actual substrates
and conditions have to be performed to ensure
adhesion and material compatibility.
1 / 2
CURE MECHANISM
Sikaflex -291 cures by reaction with atmo-
spheric moisture. At low temperatures, the wa-
ter content of the air is generally lower and the
curing reaction proceeds somewhat slower (see
diagram 1).
Diagram 1: Curing speed Sikaflex -291
CHEMICAL RESISTANCE
Sikaflex -291 is generally resistant to fresh wa-
ter, seawater, diluted acids and diluted caustic
solutions; temporarily resistant to fuels, miner-
al oils, vegetable and animal fats and oils; not
resistant to organic acids, glycolic alcohol, con-
centrated mineral acids and caustic solutions or
solvents.
METHOD OF APPLICATION
Surface Preparation
Surfaces must be clean, dry and free from
grease, oil and dust.
Surface treatment depends on the specific
nature of the substrates and is crucial for a long
lasting bond. Suggestions for surface prepara-
tion may be found on the current edition of the
appropriate Sika Pre-treatment Chart. Consider
that these suggestions are based on experience
and have in any case to be verified by tests on
original substrates.
Application
Sikaflex -291 can be processed between 5 C
and 40 C (41 F and 104 F), but changes in re-
activity and application properties have to be
considered. The optimum temperature for sub-
strate and sealant is between 15 C and 25 C
(59 F and 77 F).
Sikaflex -291 can be processed with manual,
pneumatic or electric driven piston guns.
Tooling and finishing
Tooling and finishing must be carried out within
the skin time of the product. It is recommen-
ded using Sika Slick. Other finishing agents
must be tested for suitability and compatibility
prior the use.
Removal
Uncured Sikaflex -291 can be removed from
tools and equipment with Sika Remover-208
or another suitable solvent. Once cured, the
material can only be removed mechanically.
Hands and exposed skin have to be washed im-
mediately using a suitable industrial hand
cleaner and water.
Do not use solvents on skin!
Overpainting
Sikaflex -291 can be best painted after forma-
tion of a skin. Painting could be improved by
treating the joint surface with Sika Aktivator-
100 or Sika Aktivator-205 prior to paint pro-
cess. If the paint requires a baking process (>
80 C), best performance is achieved by allow-
ing the sealant to fully cure first. All paints have
to be tested by carrying preliminary trials under
manufacturing conditions.
The elasticity of paints is usually lower than
that of sealants. This could lead to cracking of
the paint in the joint area.

DESCRIPTION
Sikaflex -292i is a non-sag 1-component poly-
urethane adhesive of thixotropic, paste-like
consistency which cures on exposure to atmo-
spheric moisture. It exhibits excellent adhesive
properties and a good mechanical strength.
Sikaflex -292i meets the low spread of flame
requirements set out by the International Mari-
time Organisation (IMO).
PRODUCT BENEFITS
Good gap-filling properties
Can be painted
Bonds well to a wide variety of substrates
Wheelmark approved
Solvent free and very low VOC
AREAS OF APPLICATION
Sikaflex -292i is suitable for structural joints in
marine constructions which will be subjected to
high dynamic stresses. It is suitable to bond
metals, particularly aluminium (including anod-
ized finishes), metal primers and paint coatings
(2-component systems), or ceramic materials,
plastics such as GRP (unsaturated polyester res-
in), ABS, etc.
Seek manufacturer s advice and perform tests
on original substrates before using Sikaflex –
292i on materials prone to stress cracking.
This product is suitable for experienced profes-
sional users only. Tests with actual substrates
and conditions have to be performed ensuring
adhesion and material compatibility.
1 / 2
CURE MECHANISM
Sikaflex -292i cures by reaction with atmo-
spheric moisture. At low temperatures the wa-
ter content of the air is generally lower and the
curing reaction proceeds somewhat slower (see
diagram 1).
Diagram 1: Curing speed for Sikaflex -292i
CHEMICAL RESISTANCE
Sikaflex -292i is generally resistant to fresh wa-
ter, seawater, diluted acids and diluted caustic
solutions; temporarily resistant to fuels, miner-
al oils, vegetable and animal fats and oils; not
resistant to organic acids, glycolic alcohol, con-
centrated mineral acids and caustic solutions or
solvents.
METHOD OF APPLICATION
Surface Preparation
Surfaces must be clean, dry and free from
grease, oil and dust. Surface treatment de-
pends on the specific nature of the substrates
and is crucial for a long lasting bond. Sugges-
tions for surface preparation may be found on
the current edition of the appropriate Sika
Pre-treatment Chart.
Consider that these suggestions are based on
experience and have in any case to be verified
by tests on original substrates.
Application
Sikaflex -292i can be processed at temperat-
ures (climate and product) between 10 C and
40 C (50 F and 104 F) but changes in reactiv-
ity and application properties have to be con-
sidered. The optimum temperature for sub-
strate and sealant is between 15 C and 25 C
(59 F and 77 F).
Consider that the viscosity will increase at low
temperature. For easy application, condition
the adhesive at ambient temperature prior to
use.
To ensure a uniform thickness of the bondline
it is recommend to apply the adhesive in form
of a triangular bead (see figure 1).
Figure 1: Recommended bead configuration.
Sikaflex -292i can be processed with manual,
pneumatic or electric driven piston guns. The
open time is significantly shorter in hot and hu-
mid climate. The parts must always be installed
within the open time. Never join bonding parts
if the adhesive has built a skin.
Tooling and finishing
Tooling and finishing must be carried out within
the skin time of the sealant. It is recommended
using Sika Slick. Other finishing agents must
be tested for suitability and compatibility prior
the use.
Removal
Uncured Sikaflex -292i can be removed from
tools and equipment with Sika Remover-208
or another suitable solvent. Once cured, the
material can only be removed mechanically.
Hands and exposed skin have to be washed im-
mediately using a suitable industrial hand
cleaner and water.
Do not use solvents on skin.
