CTC multifunctional coatings generated considerable interest at the 28th ASEFAPI Technical Congress

The multifunctional coatings designed by the CTC Technological Centre, namely, three developments featuring hydrophobic qualities, abrasion-resistant and the ability to retain transparency, caused a significant impact at the 28th ASEFAPI Technical Congress.

The presentation of these three advances linked to the KrEaTive Habitat project came by the hand of Dr Núria Mas, from CTC’s Advanced Materials and Nanomaterials team. The project’s main objective is to develop a series of intelligent coatings to be applied on materials used in the construction sector (cement, marble and fibreglass composite, among others). Her talk—entitled “New multifunctional coatings: transparent, with superhydrophobic properties and wear resistance”—opened the congress, generating much curiosity among the attendees.

Dr Mas explained how, thanks to the integration of nanoadditives, the scientists of the Cantabrian centre have achieved multifunctional coatings, whose main innovation lies in their ability to group together several features at the same time. In other words, they combine resistance to UV light, wear and abrasion, as well as superhydrophobicity.

This capacity notably increases the added value of these products and makes them ideal for the repair of monuments and heritage, as well as for innovative designs in exteriors, urban furniture, façades of buildings and houses, garden elements, etc. Not by chance have they become a way to overcome the limited wear resistance of commercial superhydrophobic materials.

Another of the most innovative elements of these developments is the integration of nanoadditives in the polymeric matrix of paints. Achieving the desired characteristics after adding resin to nanomaterials has involved many hours of study. However, the combination of nanomaterials into commercial elements and the variety of substrates tested make these developments firm candidates for application in a multitude of industrial sectors where paints are used. For example, in paints for hospitals and schools or offshore paints where superhydrophobicity and wear resistance are critical.

The ASEFAPI Congress is a major technical event that brings together more than 250 professionals from companies and research agents related to the manufacture of paints and printing inks. In this edition, held recently in Madrid, there was a total of 25 presentations of different developments as well as several parallel sessions, a poster area and a space dedicated to networking. Beyond the public exhibition, the presence of CTC in this forum was very interesting to gain an insight into the latest market trends and needs.
