Dirk Plas – President, BYK, USA
BYK makes additives for composite applications in the construction, transportation, automotive, recreation, and wind energy markets. Applications include wind blades, fiberglass tubs, boat hulls, automotive body panels, and duroskins for fiberglass doors. The additives are designed to improve the processing or air release in spray-up and lay-up manufacturing as well as the casting process (marble, solid surface). Dirk Plas, BYK-USA president, discusses his view of the composites industry.
What markets are you more focused on?
The area we’re most focused on is anything to do with energy savings, which includes “green” and wind energy. Many customers are working actively to replace existing raw materials with more sustainable materials. There’s a lot of money being invested there. There’s a very significant focus right now on developing alternative energy technologies. There’s a high demand for green products and more money going into that area. A lot of our customers need help in making these new materials work.
What challenges do your customers have?
When formulating with green products, there are challenges with regard to compatibility. Customers are always looking for ways to reduce scrap. Anytime you make a composite, you have an air release problem. Filler materials help make composites more cost competitive, and so do the wetting and dispersing additives. These additives reduce rollout time and filler increase.
Is the “green” movement here to stay?
I think so. Green doesn’t necessarily have to be expensive. Some industries will be slow to adopt, but ultimately it’s not a fad, and it’s not going away.
What is the state of the additives industry?
Like everyone else, we suffered a decline at the end of 2008 that continued through 2009. Things have started to improve; however, the market was already competitive but has become even more so. Everyone’s looking for new business, scrambling after stimulus dollars and looking for new areas. As a result, competitors are also moving into new areas. But we’re also doing the same thing. We’re not seeing a lot of consolidation, but rather more people coming into the market.
How has the market changed in the past decade?
The market for additives in composites isn’t an old market, so we’ve seen a lot of growth. New technologies are being developed and it’s still a growing market. Our company in particular started focusing on the composites industry about 20 years ago, and we began seeing strong market pickup.
Perhaps the biggest difference is that now, we get more demands or requests for composites that are highly flame-retardant because reduced emissions of the actual composite are a more important factor. In any industry, everything focuses on low VOCs. Personal safety for the workers, the people who work in manufacturing, is always important. Nanoadditives have also come on strongly in the last three to four years in the composites market. There have been a lot of government regulations, particularly in regard to styrene. ACMA has been an active voice in regard to styrene regulation.
How do you see the styrene issue playing out?
I speculate we have reached the minimum amount of styrene that we can work with. I don’t think those can go much lower. There are trends in development that are styrene-free, but I don’t think the government will push much for us to reduce styrene content. Styrene is an integral part of the polyester, which is responsible for cross-linking in chemical processes. It has over 50 years of historical use in these types of composites. It will be difficult, if not impossible, to take them out in the next few years. Alternatives to styrene do not offer same type of historical use or consistency in use. Partial replacements could occur in the near future, but we’re talking about a very long time to make a total replacement.
How will the composites industry change in the next five years?
I think lower densities and lighter weight composites will be a trend for all applications. Everyone’s always looking for stronger composites, so that will be a trend. Renewable resources will continue to grow. You’ll also see an increase in coupling agents that will increase the physical properties of composites. Nanoadditives will emerge more and more for certain applications such as antimicrobial tendencies.
In aviation, there’s a big push for carbon fiber. It’s a little bit of a fragmented, niche application market, so it’s hard for us to focus on that market. We want to though, because we believe it’s an area where composites is going to grow. Technology in aviation sometimes transfers to automotive, so we’ll see a trend in that direction.
From your viewpoint, how can composites grow?
There needs to be more applications away from steel, aluminum, and wood. The standard approach composites has had for years is converting applications, but there needs to be more of a focus on day-to-day growth. That approach has picked up in the construction market and has helped reinvigorate the infrastructure market. Those two areas have strong immediate and long-term growth opportunities.
What segments have been hit hardest?
The recreation market was down almost 80 percent in 2009. It has recouped a little bit since then, but it’ll be a long-term process to get back to where it used to be. A lot of baby boomers are coming onto the market, and they may be interested in RVs, so that might drive growth a bit. Concerning boats, manufacturers have had success with making boat hulls from composites. You can see a conversion to infusion-molding and vacuum bag from spray-up and lay-up. I think companies that make RV parts can diversify by integrating their parts into construction or fire-retardant panels.
