Stahl Launches Hypac Super-Functional Crosslinkers For High-Performance Packaging Coatings

Stahl, the global leader in speciality coatings for flexible materials, has introduced a new range of highly functional carbodiimide crosslinker products specially designed for packaging coatings.

Hypac is a group of patented crosslinkers that enable Stahl customers to manufacture high-performing, durable packaging products without compromising on sustainability or safety.

Crosslinkers improve coating performance
Crosslinkers, used for their high levels of reactivity, improve a coating’s tensile strength and resistance to cracks, abrasion, chemicals, water and heat, whilst improving adhesion to the coated material. With the help of crosslinkers, coated products can withstand a variety of climates and experience a much longer life, resulting in lower maintenance costs.

The range includes conventional isocyanate and aziridine-based crosslinkers, as well as more sustainable carbodiimide alternatives, making it versatile for customers’ application requirements.

Carbodiimide crosslinkers: better for people and the planet
Stahl’s Hypac range includes a variety of carbodiimide crosslinkers, which maintain the high performance of aziridine and isocyanate crosslinkers without using carcinogenic, mutagenic and reprotoxic (CMR) materials: Carbodiimides are defined as non-hazardous under the Global Harmonized System (GHS).

Many carbodiimide Hypac products cure at room temperature, are water-based, have a long-lasting pot life and contain zero voltatile organic compounds (VOCs), making them the most sustainable, safe and easy-to-use option for high-performance crosslinking.

Sustainable solutions without sacrificing quality
Tested using high-level expertise and equipment at our Centres of Excellence, Hypac carbodiimide crosslinkers deliver superior resistance, flexibility, and efficiency, while reducing environmental and health impacts.

Key benefits of Hypac carbodiimide crosslinkers include:

• Low toxicity and CMR-free
• Suitable for a wide range of end applications
• Long pot life exceeding 24 hours
• Proven anti-soiling properties
• Contributes to lower carbon emissions
• Non-yellowing
• Very high efficiency (on par with aziridines)
• Low curing temperature
• Strong adhesion properties

Produced in Europe but available worldwide, Hypac crosslinkers enable Stahl to achieve our purpose – Touching lives, for a better world – by providing high-performance solutions that limit impact on people and planet.
