Description
of Application
On modern ships, yachts and motor boats the joints between
different materials must be sealed to protect against
water ingress, corrosion, etc. In addition, they must
also supply an aesthetic finish to the joint.
High-performance sealant joints can be made with conventional
one-component, polyurethane-based systems, which, due
to their excellent adhesion to various substrates,
allow permanent elasticity and resistance against water
ingress and corrosion.
Conventional polyurethane sealants, however, exhibit
some sensitivity to UV radiation. After prolonged periods
of exposure the joint may exhibit fine cracks and degradation
of the surface. This does not detract from the sealing
properties, as it is only a surface effect. If a durable
surface aspect is required, the use of a specifically
formulated, UV-resistant polyurethane should be promoted.
|
Most ships and particularly luxury yachts and vessels
require a large number of such joints and hence require
the use of a high-durability
sealant. Sikaflex® -295 UV, in white or black, provides
excellent resistance against solar UV radiation and
sea water attack, the white grade also providing superior
non-yellowing characteristics.
Sikaflex® -295 UV is therefore particularly suited
for sealing such areas as deck fittings, hatches, window
rebates, etc.
