From the merger of Rental Colloid and Kreys

Our history

RCK Chemicals was founded in 2017 from the union of Rental Colloid and Kreys to consolidate the presence on the Italian and European market. Rental Colloid was founded in 1987 in Veneto, in the city of Valdobbiadene in the province of Treviso. In just a few years it expanded across Italy and Europe, and, after years of growth and successes, it has become one of the most renowned and reliable companies in the paper chemicals industry. Kreys was founded in Castelraimondo in the province of Macerata and, thanks to the long-standing experience of its technicians, is specialised in water treatment for paper mills. RCK Chemicals combines the know-how of both companies, developing new formulations and solutions and offering even more experience and professional skill.
