Stahl launches Hypac crosslinkers for high-performance packaging coatings
Stahl introduces its new range of highly functional carbodiimide crosslinker products specially designed for packaging coatings.

Stahl has launched Hypac, a group of patented crosslinkers that enable customers to manufacture high-performing, durable packaging products without compromising on sustainability or safety.
Crosslinkers, used for their high levels of reactivity, improve a coating's tensile strength and resistance to cracks, abrasion, chemicals, water and heat, while 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.
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 volatile organic compounds (VOCs), making them the most sustainable, safe and easy-to-use option for high-performance crosslinking.
Tested using high-level expertise and equipment at the company's Centers 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 formulation, suitability for a wide range of end applications, long pot life exceeding 24 hours, proven anti-soiling properties, contribution to lower carbon emissions, non-yellowing characteristics, very high efficiency on par with aziridines, low curing temperature and strong adhesion properties.
