When one speaks about epoxy one has to differentiate
between common epoxy or other kinds of resins such as
polyester and Lignu® Impregnating resin.
Traditional epoxy or other resins are thick and will
prevent air circulation and won´t allow the wood
to breathe. This has caused many people to refrain form
using epoxy since problems can develop in the wood under
the epoxy that are not discovered due to the epoxy.
Lignu® Impregnating resin is an epoxy manufactured
from resins mainly derived from wood. This is very thin
(it runs like water) and will penetrate the wood deeper
than any other product we know of. It has the best durability
and protective ability we have ever experienced and
it allows the wood to breathe. Its biggest advantage
is its ability to penetrate the end section of wood,
cracks between planks and so on, where rot and bacterial
infestations start.
Lignu® Impregnating resin is more expensive than
other epoxy resins that are manufactured from petrochemical
products, but has a better bonding with the wood and
is stronger and more flexible.
Lignu® Impregnating resin is a clear epoxy and
seals better than any other product we have tested.

Now there is a modern way of improving the surface
protection your boat needs in order to ride through
all the various conditions of the climate and environment.
Boat owners spend a lot of time on scraping, sanding
and varnishing their boats. But the varnish gets dull
after a year or even 6 months, it cracks, peels and
comes off and one has to sand it all off the next spring
and start all over again.
Lignu® Impregnating resin is a deeply active impregnating
resin that protects against rot and gives the varnish
a superior bonding with wood.
Wood contains water. Varnish is based on oil. Water
and oil don't mix so the varnish can not get a optimum
bonding with the wood. Lignu® Impregnating resin,
however, dissolves water and cures with the wood. At
the same time Lignu® Impregnating resin has the
ability to chemically bond with the varnish. Lignu®
Impregnating resin is very flexible so when something
impacts with the varnish it will not crack, but will
stay bonded with the Lignu® Impregnating resin which
is chemically bonded with the wood. The point of damage
will stay intact. It will not develop dark spots and
the wood will not swell so the varnish cracks and peels.
The only "damage" is usually a small, almost
invisible dent in the wood. It takes a lot longer for
Lignu® Impregnating resin to break down due to UV
rays, than it takes for wood fibres. This means the
wood fibres will not age as fast due to UV rays since
Lignu® Impregnating resin is chemically bonded with
the wood.
