Coelan
COELAN®
is a liquid one component polyurethane coating that remains
permanently flexible. The hardening component is moisture
in the air. Since it is a single component product, it is
easy to apply.
FLÛSSIGKUNSTSTOFFE
is German for “liquid plastic”. Coelan Marine Coating is a
proprietary and highly refined product. It is neither paint
or varnish.
Due
to its flexibility COELAN® will expand and contract
along with changes in the wood due to moisture, heat, and
mechanical stress. And; leaks are usually stopped. In addition;
COELAN® is extremely resistant to UV and withstands
damage due to abrasion and foot traffic. In fact, COELAN® contains re-growth properties which allow the coating
to automatically mend minor damage due to scuffing and abrasion.
Elongation
is approximately 335 %. This means that COELAN® can be stretched to three times its length before breaking.
Product
life is at least 5 years when applied in accordance with the
instructions. instructions but many testimonies from boat
owners report a ideal look even after more than 10 years.
COELAN® coating and the associated primer, filters away 99 % of UV
light. It is used on boats in the Mediterranean and Caribbean
Sea and lasts for many years. We have clients who have experienced
product life in excess of more than 10 years.
It
retains it’s gloss for years. Little if any touch up required.
When applied per
manufacturers instructions, Coelan is a very resilient coating
and stands up to heavy wear. Very useful for steps, benches,
floorboards etc.
Yes,
it bonds very well to these woods. The appropriate primer
affects this. Do not use thinners to remove oil and no other
sealers are required. Just dry sand with 80 grain and vacuum
thoroughly before putting the primer on.
Yes,
COELAN® bonds to all polyurethane sealers, like
Sikkaflex etc. Like may other products it does NOT bond to
silicone sealers or silicone based products.
Yes,
a matte finish can be applied on top of the last coating.
It should be applied thinly as otherwise the matte effect
will not come out. It is not recommended for decks or floorboards
as it is more slippery than the gloss finish. This is due
to the microscopic sized glass particles which create the
overall matte effect.
COELAN® is far less slippery than ordinary varnish due to it’s “rubbery”
texture. Like most surfaces when wet, a risk of slipping always
exists. There is a very effective anti-slip application possible
using COELAN®’s glass beads along with the optional
use of the ANTI-SLIP pre-punched tape.
No,
the COELAN® coating has a micro porous structure
which allows the transfer of moisture or condensation between
the wood and the environment. This unique ability will prevent
the properly applied coating from cracking or lifting. Deterioration
of the wood is frequently a problem with most paint or varnish
as moisture or the effects of UV light will erode the coating
or wood.
COELAN® coating, allows the wood to remain at it’s natural low moisture
equilibrium point. The wood must be dry (max. 15 % moisture
content) when applying COELAN®. Refer
to the detailed user guidelines.
The
microscopic coating porosity can, in very wet conditions,
result in a milky condensation under the top layer of the
coating. There is NO damage to the coating. In fact this is
proof of the coatings ability to transfer moisture. In this
case the transfer is inhibited by overlying moisture or small
pools of water. The milky water condensation will disappear.
This normal transfer capability is restored due to the combined
effects of sun and wind.
A
great advantage of the product is WATER-VAPOUR EXCHANGE. This
keeps the natural process of wood to “breath” and exchange
moisture. The innovation makes it possible that the natural
condensation water has the ability to vaporise in a natural
process. This protects the wood core from a creeping rotten
process. Further like a valve it provides a way for the condensation
to vaporisation and it avoids the tear and pealing of the
coating caused by vapour pressure if not able to vaporise.
The WATER-VAPOUR EXCHANGE of Coelan provide for an application
that is good for many years! The typical WATER-VAPOUR EXCHANGE
through the coating will be visible by a temporary
dimming of the surface or parts of it (spots) at more moistures areas on the surface - an indication for
the correct function of our system. I.e. this can proofed
in the morning after heavy rainfalls, this milky colour disappears
as soon as the sun shines again.
Unopened,
at least 12 months. Opened tins are best used the same day
or very shortly thereafter due to the effects of humidity
and heat. Some thinning may be required. Careful calculation
of product requirements will help you to order appropriate
sized containers. It is also a good idea to order several
smaller sized tins for future touch up. Every shipment of
Coelan Marine Coating Products is given a rigid quality control
check prior to leaving the factory.
COELAN® is a German company which is a leader in the industrial coating
field. COELAN ® has specialized in designing chemical products
since 1952. More recently, in 1992, COELAN chemical engineers
adapted these building related products to the marine and
boating environment. COELAN marine coatings have enjoyed
exceptional success in Europe.
In
Germany COELAN Industry Products have been on the market for
many years. Based on the success the Coelan Marine Product
line has been developed and is on the market for many years
now. It’s known in Europe as a top quality product and has
proven itself in the Mediterranean where varnishes usually
disintegrate in half a year. Articles in recent boating publications
have also sustained COELAN quality and claims.
Between
5 and 30 degrees centigrade. No direct sun on surface! Use
in constant or descending temperature. Temperature itself
is not the prime concern. Relative air humidity (moisture)
is more influential. High humidity = fast drying, (+/- 2 hours),
low humidity = slow drying (+/- 6 – 12 hours). Use of COELAN
Retardation Agent may be required.
In
order to achieve optimum long term results and ensure maximum
product characteristics, the final coating thickness must
be 1.0 mm (0.039”).
On
horizontal surfaces this value is normally reached in 5 very
full layers, or 7/8 layers (thinned) on vertical surfaces.
The COELAN® must be thinned by +/- 25 % to prevent
dripping. Only use the special COELAN® THINNER.
COELAN® can be thinned to work more easily but
always apply a rich full coat in order to get the best results.
If possible, measure the thickness of the wood prior to coating
and then apply 5 layers totalling 1.0 mm thick.
Between
2 – 4 hours in normal humidity conditions. Thereafter the
next coat can be applied without sanding. One can work quite
fast this way.
No.
No sanding is required if the next coat is applied within
14 days. The bonding is then chemical. This saves a lot of
work. After 14 days sand with grain 80 to get good bondage.
Yes,
COELAN® is a very strong adhesive as well. So take
care with putting COELAN® coated objects on top
of surfaces, they will glue together. This adhesive effect
between two coated objects cures for approx. 14 days until
the coating is fully set. So take care not to lay two coated
objects against each other. Use wax paper in between if necessary.
Use gloves for your hands.
Normally
apply COELAN® 0,5 centimeter on top of the anti
fouling. Waterline can be painted with COELAN® or a normal strong waterline paint. The product should not
be applied below the waterline.
Please
see our User
Guide or the detailed Application
Instructions on our web site. Further a Working Tips Index is provided
on our web site for your assistance.
Use
a heat gun to soften the coating and then lift with a wide
putty knife. For localized areas; cut out damaged, area including
sufficient boundary, with sharp utility knife. Re-sand, re-prime
and build up several layers of coating to ensure minimum of
1.0 mm thickness and smooth transition onto adjacent existing
coating.
