solvent manufacturer's warnings and
instruction for use. Once cured, the material
can only be removed mechanically. Hands
and exposed skin should be washed
immediately using a suitable industrial hand
cleaner and water. Do not use solvents on
skin!
Overpainting
Sikaflex-221 can be overpainted when tack-
free. The paint and paint process must be
tested for compatibility by carrying out
preliminary trials. Sikaflex®-221 should not
be exposed to baking temperatures until it has
attained full cure. It should be understood that
the hardness and film thickness of the paint
may impair the elasticity of the sealant and
lead to cracking of the paint film with time.
Limitations
Avoid application below 40°F (5°C) and
above 105°F (40°C). Do not apply on frozen
or wet surfaces or through standing water. Do
not apply over silicones or in the presence of
curing silicones. Contact with alcohol or
alcohol containing solvents will prevent cure.
Deliberate misuse by inhalation of vapors
may be harmful or fatal.
