Since 1973, Soprima has specialised in precoating in the automotive industry. Now as a part of the LINKSY Group, the company works in synergy – along with Prelok – to provide the best fixing solutions with expertise in assembly trades.
Soprima’s technique consists of applying, on any type of threaded or smooth fastener, a micro encapsulated adhesive that activates while mounted. Polymerising, the adhesive therefore ensures the locking of the part and the sealing of the assembly.
Soprima points out that this technology, developed thirty years ago in the automotive industry, is an advantageous alternative of the classical but costly method of thread lockers. Precoating gradually found itself in many industries, including aeronautics, due to its ease of use and its economical and favourable technique – vibration resistant, easy conception, high productivity, easy technical visual control, reduction of the assembly costs, and being the most effective anti-loosening solution.
Prelok and Soprima provide precoating of nearly 200 million pieces a year, in small and in large series. “We work upstream from the engineering office of our clients and are advocates of technical solutions, in co-development. We also perform the tests and industrialisation and can provide the parts that will be pre-coated,” comments Isabelle Boulineau, sales manager at Soprima.
