Darex range of compounds is aimed at high-speed liner use

A Darex family of sealing compounds for nozzle application on non-round food ends has been added to Henkel’s portfolio in North America.

The WBC 8790 range has been introduced in response to increasing investment in high-speed copy liners that have been replacing dated platen-and-die and shower-head application machines.

“Our WBC 8790 family of products was specifically developed for this demanding application,” says John Stankiewicz, head of product development for Henkel AA Metals North America, which now includes the Darex product portfolio. “The high solids and customised product rheology are dialled in for specific copy liner equipment. The result is superior application with optimised compound flow out and coverage without compound spill over.”

The compound range is also said to have excellent separation and mechanical stability. This reduces liner mechanical handling requirements and increases application efficiency, reducing down-time and lowering camera spoilage rates.

“We have eliminated the decades-old requirements to add non-web and other modifiers to eliminate webbing or curtains,” adds Stankiewicz. “We’ve even built in superior chemical resistance, i.e. compatible with fatty-food packs.”

Henkel acquired the Darex business from GCP Applied Technologies in July 2017. Stankiewicz, who is also global technology leader for Henkel Darex can sealants, has worked with Darex for more than 30 years.

As well as can sealants, Henkel offers canmakers a one-stop shop for its can chemistry needs, including front end can forming lubricants and cleaners, mobility enhancers, internal and external can coatings.

With food safety the number one priority for canmakers, Henkel has implemented a ‘Triple Safety’ philosophy for its can coatings and sealants. The company’s risk assessment process looks beyond regulations and analytical assessment, to demonstrate that its coatings and sealants show no evidence of endocrine disruption, DNA-reactivity nor toxicological concerns.

“These are exciting times for the industry,” remarks Stankiewicz. “We are experiencing high demand for food cans and unprecedented recent investment in the beverage can as the preferred sustainable consumer package.

“As an industry, we must maintain focus on cost effective, sustainable solutions while anticipating new trends in consumer preferences. However, we cannot sacrifice the impeccable safety record of the can. Consumers trust the can as a reliable, durable and safe, especially in these unusual times.”
