The loading ramp touches down on the harbor quay and heavy-duty vehicles begin to stream from the depths of the ship. The most active residents in the local area are preparing to file a new complaint about the noise caused by the vehicles driving down the ramp. The ramp is in need of a new coating that can withstand heavy wear, reduce noise, and dry quickly, but the ship will not be in the harbor long enough and there are no replacement ramps available. A seemingly impossible equation, but Lännen Pinnoitetyö and Teknos had a solution.
Lännen Pinnoitetyö Oy, a company founded in 2012, is a specialist in polyurea coatings and is a trailblazer in Finland. In summer 2015, the men from Lännen Pinnoitetyö were pleased to hear rumors that Teknos was launching its own elastomeric coating based purely on polyurea technology – TEKNOPUR 300.
"Until now, we had bought a product from an American manufacturer, but they had delivery problems disappointingly often. We were required to pay for the orders in advance, yet it was not always certain whether the coatings would ever arrive," says Ville Pihlava, who is responsible for Lännen Pinnoitetyö's sales and administration.
"Now that we buy the product from Teknos, we do not need to order a truck-load at a time, and we also do not need to take care of storing the product. It is much easier for us to operate and run our business when we do not need to tie up the company's capital in a large quantity of goods," says Ville Pihlava.
There is not always time to wait for a paint or coating to dry. The Viking Line loading ramp referred to at the beginning of this article needed to be back in service eight hours after the coating had been sprayed on.
"The day before we sprayed the coating, we sand-blasted the ramp. When the ship departed from the harbor the following morning, we first applied a primer coat of TEKNOPUR SEALER 100 polyurethane varnish before spraying 10 mm of TEKNOPUR 300 elastomeric coating onto the surface," Ville Pihlava says.
TEKNOPUR 300 can be walked on 40 seconds after spraying, and the paint film hardens completely after approximately one day.
"With the exception of some small marks visible at the end of the ramp, there are no blemishes on the coating, even though there were vehicles driving over it the very same day. In addition, I have not heard of any further complaints being filed about the noise caused by vehicles," Ville Pihlava says.
The quick and durable coating is very well suited to a range of production plant applications.
"It is a great benefit that the coating dries quickly because shutting down a production plant while service work takes place can be expensive. For example, we coated a tank at a paper mill over one weekend. If the tank had been coated with epoxy, it would not have dried in time," Pihlava says.
Lännen Pinnoitetyö has built up extensive experience with Teknos' polyurea coatings.
"TEKNOPUR 300 is essential for water insulation jobs because it can be used to create a seamless surface and the coated area can be taken into use quickly. This is a major benefit for coating sites such as yard decks and felt-covered roofs."
Lännen Pinnoitetyö has also praised Teknos' technical support. "American polyurea suppliers could have a hundred sales representatives but no technical support. It seems as if they have never even heard of the concept," Ville Pihlava laughs.
"We also improved our credibility in the eyes of our own customers when Teknos began manufacturing polyurea coatings," Pihlava says.
Even a good product can have its reputation destroyed by poor workmanship. "If work is performed badly, it also detracts from the credibility of the product. The work should be done right the first time," Pihlava says.
The recipe for a successful coating project sounds fairly simple: a good, functional product in the hands of expert coating professionals.
How to become a certified polyurea applicator? We train all our new polyurea customers to excel in all aspects of polyurea usage, including product chemistry, theory, and practical issues such as equipment, safety, spraying technique, and troubleshooting.
In addition to local polyurea training, we often participate in the first sprayings at the customer site to a successful start and smooth first deployment of polyurea coating.
The floor of the ventilation machine room in the training center under construction at Teknos' Rajamäki plant was coated with polyurea. The new concrete absorbs more primer varnish than the old concrete floor, so the floor of the machine room was first given two coats of TEKNOFLOOR PRIMER 306F epoxy varnish. After this, TEKNOPUR 300 elastomeric coating was sprayed on by professionals, who completed the job very quickly and made it look effortless.
Teknos' Technology and Training Center GALLUS was completed in 2017, and now serving as a trial paint shop and a training center for Teknos' own personnel and customers.
