Who are we

We stand for innovative solutions! 

Prokol has been developing and producing synthetic plastics for more than 30 years. Our products are used for coating and protecting buildings and structures. During the past 15 years, we have developed into a true specialist in the field of polyurea systems. In addition to the so-called hotspray systems, our supply programme does of course include products based on polyurea, epoxy, polyurethane and various variants thereof, all of which are suited for hand-application. 

Out there, together! 

Prokol likes to be close to its customers. That is why we attach great importance to our employees truly understanding customers. We achieve this by mainly deploying employees with practical experience. Our hands-on experience is of great added value for our customer. 

Global network 

Prokol’s products are recommended by our technical specialists from our offices in the Netherlands, the United Kingdom and the United States of America. In addition, we now work with expert partners in more than 30 countries. Our products are now finding their way across a large part of the world. 

Hands-on expert 

After 30 years, Prokol can honestly say it knows what motivates the customer. 

In addition, we know better than anyone else that every problem requires a different solution. This way, we arrive at the best possible end result for all parties. Our website gives you an impression of the possibilities. We deliberately state “impression” of the possibilities, because it is impossible to present all solutions to you online. We do in fact prefer to talk to you directly and listen to the challenge you want us to deal with for you. 

If you have any questions, don’t hesitate to contact us. You can call +31 85 78 200 20 or, alternatively, e-mail us at info@prokol.nl.
