For manufacturers of waxes, solvents and additives, 2006 was a year of mixed results. Business was
“Noveon continued to perform very well in 2006, especially in our wax and additives businesses,” said Josh Rosenheck, commercial platform manager, Noveon Surface Modifiers. “Although it will require a lot of work from our entire team, we expect this to continue into 2007.”
“Keim-Additec experienced double-digit growth in 2006, although the water-based industry did not fare nearly as well,” said Alan Kalmikoff, president of Keim-Additec Surface USA, LLC. “Our growth was due in part to the relative economy of scale of our still-new business to the U.S. market.”
“Spiraling raw material costs have challenged us to find additional ways to take out costs to mitigate the impact on our margins and pricing,” said Guy Trerotola, market manager, commercial offset for Hexion Specialty Chemicals. “With the numerous raw material increases over the past two years it has become successively more difficult to find new opportunities to reduce costs. In 2006 we were faced with the reality of further margin contraction and more pass through costs in the form of price increases.”
“In general, the Elementis business was good in 2006,” said Sel Avci, marketing manager for Elementis Specialties. “Although we have seen decline in publication business, we saw improvement in water-based liquid ink business additives. We expect the same trend in 2007.”
“We’ve been on the leading edge of developing UV/EB curable ink resins and additives for low extractable/low odor, indirect food packaging printing which comply with European REACH regulations,” said Michael Kucharski, marketing manager – graphics, Americas for Cytec. “For 2007, our expectations are that we will continue developing new products which also meet or exceed new opportunities created by the FDA.”
“2006 was a very good year for Colloides Naturels, especially since we launched two new products into the lithography market,” said Sharrann Simmons, vice president and general manager, Colloides Naturels, Inc.
The higher costs of raw materials impacted pricing throughout the supply chain for ink manufacturers, and waxes and additives were no exception.
“Supply seems to be stable for our types of raw materials; however, the prices have increased several times since early 2006,” said Joon Choo, vice president of marketing for Shamrock Technologies.
“Raw material prices continue to increase while supplies of certain classes of materials continue to tighten,” Mr. Rosenheck noted.
“We chose to hold price increases to a minimum in 2006, even in the face of higher energy costs for transportation and the fluctuating exchange rates,” Mr. Kalmikoff said. “There were some shortages of certain PE types from Germany this summer, but the relative supply situation overall is OK.”
“Raw material pricing is still volatile – it’s a see-saw market right now,” Mr. Kucharski said.
“The acacia gum (gum arabic) market has stabilized and pricing is now very attractive vs. other indirect substitutes,” Ms. Simmons said. “Acacia gum is harvested from more than 15 countries, which contributes to the stable supply situation worldwide.”
The consolidation that occurred in the ink industry has led to changes in the marketplace, including an increasing emphasis on the bottom line.
“The most obvious trend is the consolidation of the ink companies and cutbacks in R&D efforts,” Mr. Avci noted. “The ink companies are pretty much focused on increasing their bottom line profits by consolidation of their business units as well as their product lines. Most lab or technical efforts are in lowering the cost of their formulations.”
“The ink industry continues to demand lower prices first, followed by innovative problem solving technology,” Mr. Rosenheck said.
“It is extremely difficult to create broad-based interest in water-based additive technology, however, innovative and differentiated, due to the on-going distractions caused by consolidations of many ink companies,” Mr. Kalmikoff said.
“There are strong economic pressure to lower costs, as well as consumer pressure to have safe products with more natural ingredients,” Ms. Simmons added.
“The continued increases in the cost of raw materials has resulted in the realization that ink prices must be advanced if producers expect to be viable and sustainable,” Mr. Trerotola said. “Multiple ink price increases in the same year were historically unprecedented. They are now considered unavoidable, and a prudent business practice when faced with the alternative.”
Still, there are opportunities for new technologies. For example, Mr. Choo noted the continuing push in use of radiation-cured inks as well as RFIDs. Mr. Kucharski sees growth potential in packaging.
“We’re seeing market demands for developing new inks that adhere to everything, and for ink additives to be more ‘packaging friendly,’” Mr. Kucharski said. “The emerging market segments of packaging graphics, commercial printing, publishing and industrial graphics are especially looking for more innovation. Also, we’re seeing UV/EB curable technologies continuing to attract more users.”
There are many challenges ahead for ink manufacturers and their suppliers, who are working hard to develop solutions.
Potential shortages are a major concern, and Mr. Rosenheck noted that Noveon is in a strong position to avoid such shortages.
“The most difficult challenges are raw material shortages due to an ever changing oil market, competing with low cost imported products and shorter turnaround times of finished goods,” Mr. Rosenheck said. “Presently, Noveon is dealing with these challenges by continuing to grow our extremely strong supply positions with our raw material suppliers. Looking towards the future, Noveon is utilizing its corporate technical resources, in conjunction with its parent company, Lubrizol, to prepare for the changing raw material markets. Through corporate research programs, we are looking to have tighter control on raw materials by creating them internally to offer our customers a more stable supply and cost.”
Overseas competition is a challenge. Mr. Choo pointed to stability in pricing and competition of overseas supply as challenges, adding that Shamrock Technologies is responding to those challenges by spreading its risks by investing more in its China plant, expanding production in its Belgium plant and focusing on global coordination of critical operational functions.
“The increase in the volume of finished goods being produced in Asia is a significant challenge for North America and Europe,” Mr. Trerotola said. “Asian sourced packaging and print volumes parallel this trend.”
“Hexion is strategically located throughout the world,” Mr. Trerotola added. “We are able to take advantage of the most economical regional raw material sources. We continue to research more efficient and renewable raw materials and manufacturing processes.”
Ink manufacturers have a major need for innovation, and suppliers can play a key role in helping ink manufacturers differentiate their products.
“Ink companies struggle to differentiate themselves, and in doing so, struggle to get margins up,” Mr. Kalmikoff said. “Keim-Additec continues to offer innovative materials for the water-based markets.”
“The converter base is shrinking because of consolidation,” Mr. Kucharski said. “Everyone in the graphics industry will have to maximize their positions in the value chain. We’re developing innovative UV/EB curable ink resins and additives, that in turn, help our customers successfully differentiate themselves in an increasingly global marketplace. Also, we’re enhancing our technical service, R&D, and trial ink capabilities.”
“Long term, the challenge will always be how to deliver the highest quality print image for the lowest cost,” Ms. Simmons noted. “CNI continues to be the leader in product innovation as evidenced by our launch of two new products this year.”
