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.

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).

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.
