Chemical and materials manufacturing facilities play a major role in just about every facet of our lives but few people are aware of this industry’s role in keeping other sectors of our economy humming – think chemicals for newspaper printing presses, recycling water, cleaning boilers…the list goes on. Guardian Chemicals provides over 400 chemicals products for multiple applications and they have four divisions that cater to a wide range of sectors. One thing is common across these industries – they’re looking for products that are not only effective and reasonably priced, but environmentally safe as well - a tough juggling act from my point of view but a manageable challenge for their research and development team.
The most common binder used in making these boards is formaldehyde, a chemical that is of concern to the wood panel industry because of the risk of cancer. The industry has imposed tighter controls on the use of formaldehyde and most mills in Europe and North America are switching to resins that are free of them.
Although these resins are safer to use, some cause excessive buildup on panel pressing machines, thereby slowing production. So the smart scientists at Guardian Chemicals have formulated a release agent called Pressguard that prevents this sticky resin buildup from occurring. In the picture above, the wood panel is sprayed with the release agent before the surface of the metal press comes into contact with the panel. Unlike other release agents on the market, Pressguard does not require any elaborate application process so it keeps the cost of board manufacturing low and our furniture affordable for us.
In the picture above, a computer-controlled spray boom on the back of a distributor truck is spraying a county road with Roadtek. Depending on the weather, the road is typically tack free (i.e. not sticky) within 4 to 6 hours. At that stage, the area may be reopened while the sealer coat continues to cure. It reaches full strength within 10 to 14 days.
Here's what a country road looks like after it’s sprayed. Looks like you'll have a few less trips to the carwash this fall! It’s remarkable to see a local company develop such innovate products that will ultimately have a positive impact on industry and the environment.
