Stahl Launches Hypac Super Functional Crosslinkers For High Performance Packaging Coatings
HZ info2025-08-01 09:29
Waalwijk, the Netherlands, 17 July 2025 – 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 aziri-dine-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 aziri-dine 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 aziri-dines)
■ Low curing temperature
■ Strong adhesion properties
