2009 Waterborne Automotive Coatings Webinar

Hosted by PPRC and Sponsored by EPA Region 10.

Overview

Want to learn more about the specific brands of waterborne coatings, the pros and cons of using waterborne, and what it takes to make the switch? This webinar features an hour long presentation from instructors and shops that have made the switch to waterborne coatings, followed by a second hour of questions and answers. Due to time contraints, those questions not answered live were sent out to each of the panelists, with the responses posted under Q&A below.

Speakers:

Larry Hults (I-CAR) - Larry is a waterborne coating instructor for I-CAR. He addresses the general waterborne coating technology and covers commonalities across the different paint manufacturer lines. These commonalities include reduced VOCs, better blending and color match, ease of use, etc.

Kevin Stalder (Driven Autobody, Anchorage, AK) - Kevin is the owner of Driven Autobody and has been using PPG's waterborne line for about 1.5 years. Before choosing PPG, he tried out several lines including BASF, DuPont and the Martin Senour brand from NAPA. In addition to running a "Green Star" business in Alaska, Kevin also serves on the board of Green Stars and helps other businesses to become better environmental stewards. He is a huge advocate of waterborne coatings and claims they are a superior product that is much more economical than solvent-based coatings.

Jerry Richardson (Advanced Collision Repair, Seaside, OR) - Advanced Collision Repair has been using BASF's waterborne coating line for several years. As a shop owner in a ocean resort town, Jerry is keenly aware of his impact on the surrounding community. He has been involved in the development and application of waterborne coatings for more than a decade and has been involved in the collision repair industry for more than four decades. He is a 2009 recipient of EPA's SBEAP Environmental Stewardship Award for achievement in pollution prevention, industrial environmental leadership and community environmental leadership.

Matt Thornton (Parks Royal, Boise, ID) - Mark is the owner of Parks Royal auto body and has been using BASF's Glasurit 90 line for over a year.

Greg Richards (Clover Park Technical College, WA) - Greg is an instructor at Clover Park's collision repair program, which is unique in that they exclusively teach with waterborne coatings and have been doing so for over a year.

Q&A:

What size air gun nozzle do you use with waterborne primer? Many of the manufacturers recommend a 1.2-1.5 mm fluid tip; one recommends 1.4-1.7. Larger tips sizes may be recommended for higher ambient temperatures.

Are there funding resources a small shop could tap into in order to help offset any capital investment needed to make the conversion? If the business is located in King County, it probably is eligible for the Voucher Incentive Program which can pay 50% reimbursement up to $500 to make improvements in the management of hazardous materials and the disposal of hazardous waste. This would include making the conversion to water borne. If you know of any businesses that want to make this switch, please have them contact me, Patrick Hoermann.

Does adding flex additive extend the drying time of the material? The panelists did not address this question. However, two manufacturers did provide a response.  PPG says it has no recommendations for flex additive with waterborne; flex only goes in clearcoat and single-stage paint.  Sherwin-Williams says it does not have any flex additive for the AWX waterborne system.

Do waterborne basecoats still carry VOC's? Yes, on average about 10% organic solvents versus 85% for solvent based automotive paints.

I have heard of match problems when blending the waterborne product with high base solid solvent products. Have you heard of this and is there a good workaround? I have not heard of blending issues with any waterborne paint. Just the opposite seems to be the case. Shops using waterborne report improved color match and blending. You can topcoat over solvent based products with waterborne just as you would with another solvent based product.

It was mentioned that some states have switched over to water-based paints. What states have made the switch? Are there any federally proposed regulations for waterbased paints that anyone is aware of? California is the state we mentioned but they only require waterborne primers. There are states with more restrictions than the national rule, which does not require waterborne base coats. These include Massachusetts, Delaware and the District of Columbia. There are also metropolitan areas that have more restrictions. These include Houston, Dallas, Los Angeles, San Diego, San Francisco, Chicago and north along the lake, and Nashville. This list may continue to grow.

Does anyone have a list of the manufacturers with contact information and can it be made available? Manufacturers distributing in the United States, as of a couple of months ago, include AkzoNobel, BASF, DuPont, PPG, Sherwin Williams and Standox. A local supplier should be easy to find online or in the phone book. The local supplier would be a source for product information, support and training.

Is Clover Park marketing their program to students and/or potential employers as a "green economy/green jobs" option? Is there increasing interest in your program?. It is not currently part of our marketing strategy, although we are developing a plan that promotes our use of waterborne paint in our marketing efforts. We pursued the use of waterborne because we felt it was the "right thing to do."
