From the Sector

January 2024 marks the official birth of ERCA TCS (Textile Chemical Solutions), a business unit of ERCA S.p.A. with a focus on the textile market. Founded in the 1960s, ERCA S.p.A. is an Italian company, present with six plants in three macro-regions: Europe, Latin America and Asia. The ERCA group produces specialty and auxiliary chemicals with a responsible innovation approach and its production covers several markets: textiles, cosmetics, polyurethanes, concrete.

Why a business unit that caters solely to the textile industry? The decision to give birth to ERCA TCS comes from the desire to be a unique and innovative reference point for ERCA's customers, with products and
services designed specifically for the needs of today's textile industry, grappling with the challenges and
opportunities of sustainability and responsible production.

ERCA TCS bases its activities on the principles of "Green Chemistry" with the aim of offering the textile industry chemical solutions that make the concepts of safety, performance and circularity a reality. The chemical auxiliaries of ERCA TCS are the result of a vision that incorporates responsible innovation, continuous research, and a desire to offer to the market effective yet ethically, environmentally, and economically sustainable solutions.

The green, high tech and circular commitment of ERCA TCS is demonstrated by a product and brand range that is totally based on the circular economy, which started from a problem - the disposal of used vegetable oil - and turned it into a resource, into a raw material for the production of chemical auxiliaries for the textile industry: REVECOL®, the circular range of high-performance, made-in-Italy, GRS-certified chemical auxiliaries. The REVECOL® range can be used on any type of fiber, recycled or not.

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.
