Liquid epoxy resins

Our company manufactures a wide range of epoxide resins varying in their elementary properties and purpose of their use. Our wide production assortment allows for choosing the right resin for every application starting from certified resins for the aerospace industry, ending with waterproof resins to make boats.

Our assortment of epoxide resins includes special types developed to be used in the aerospace industry. They are resins suitable for manufacturing fibreglass parts for ultra-light aircraft, airplanes, glides, helicopters, gyroplanes and other flight-able machines.

Besides resins to be used in aerospace manufacturing applications, our assortment also includes resins for current applications with fibreglass products having to achieve excellent mechanical properties. Those features are exactly achieved by our resins that can be used in manufacturing models, boats, canoes, pressure vessels, surfs, wrapped tubes, production moulds, etc.

Our company’s production assortment also includes foaming-in epoxide systems which are used thanks to their properties to fill up and reinforce cavities and hollow spaces. Once mixing its components, the volume will expand to 150 – 550% (according to the content of the swelling agent) to make a hard foam-like structure. These systems are suitable to manufacture surfing boards, boats, aircraft, cars or wind power plants.
