It uses no chemicals or abrasives, but rather photons to quickly and cleanly vaporize hard coatings. Watch as three different Laser Photonics CleanTech™ lasers power through heavy, baked on powder coating to reveal clean steel below in about thirty seconds. https://youtu.be/f5MLf_SG6qU Mark Kourihttps://laserphotonics.comnoreply@blogger.comtag:blogger.com,1999:blog-6576346347573188227.post-38751706486161654212019-04-25T11:25:48.804-07:002019-04-25T11:25:48.804-07:00Does anyone know if B17 is admissible across the b...Does anyone know if B17 is admissible across the border into Canada with no issues?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6576346347573188227.post-70365807370075340652019-03-19T00:07:08.328-07:002019-03-19T00:07:08.328-07:00Phil, that is a possibility. If you go to my arti...Phil, that is a possibility. If you go to my article "alternatives to media-blasting" you will see other ways mechanical methods for stripping parts. Just keep in mind that stripping powder coat, even with grinders is a tedious process and you will undoubtedly remove some metal in the process. As far as seeing swirl marks in the surface, this depends on the aggressiveness of the discs you are using and the powder itself. I would recommend doing some test pieces to figure out what method is acceptable to you and then go from there. I find that finishing the surface with 220 grit, either by hand or by machine sanding, is good for powder coating. <br /><br />I have used Jasco's stripper and it is probably the best stripper that is available locally, but it is not hugely effective on powder coating. It takes quite a few applications to strip powder coat and at ~$15 a quart, I find that it is not worth it. <br /><br />Understanding that you are a DIY'er and you probably don't want B17 in your garage, there is another option that I have used that I think is a lot more forgiving. It is still dangerous stuff but the fumes aren't nearly as bad. It is called Powder Strip PS-1L and it costs $160 for 5 gallons currently. Sounds expensive, but I find that having a 5 gallon bucket of it is great for smaller parts. I keep it in a 5 gallon bucket with a screw on lid and it can last a year or so in a DIY setting. It doesn't strip as fast as Benco, but it works much better than anything I have bought off the shelf at local stores. Hope that helps.

Dipping the trailer would be very expensive because of tank size and the amount of stipper you would need. Also, a trailer will probably have lots of crevices and pockets that you will not be able to sufficiently powder coat after stripping and rust would be an issue in these areas if they are bare metal. An alternative is using towels soaked in stripper and wrapping them or laying them on large surfaces and letting them sit. However, this his very dangerous as B17 burns skin on contact and its dangerous to breathe in. <br /><br />In my opinion, the best options for stripping a trailer that large is media blasting like you did or a gel/paste stripper that will stay on the surface. Benco has semi-paste strippers for items to large to fit in a dip tank. Here are 3 options on the Benco website: https://www.bencosales.com/metal-strippers/semi-paste-strippers/ <br /><br />Unfortunately, I do not have personal experience with any of them but if you call Benco about this, I am sure they will be very helpful in answering questions. As with any powder coat strippers, make sure to be as careful as possible and wear all recommended personal protection equipment.

The stripped powder coat will remain in the liquid after stripping a part and once you have a buildup of that, it will become diluted and lose its effectiveness. It can be strained out however. The only thing that really gives it an expiration date is that it will slowly evaporate over time.

The best option really depends on what type of powder coat operation it is. For any serious shop that does a lot of coating, B17 is likely the best choice because it removes powder very quickly and doesn't leave anything left behind on the metal. The safer strippers work great in DIY powder coating or home-shop operations where the user doesn't mind waiting longer for the stipper to work. Thanks for posting your experience. Just make sure you and your employees are trained in the safe use of B17 to minimize accidents.

I started off just stripping using Greensolv, the material was truckd in from Canada, Montreal I believe. We have two large heated tanks that are about 1000 gal each. We strip wheels and have baskets made up to lower into the tanks with a job crane. This stuff works great initially heated up to about 180F. It takes about 2 hours to strip most coatings from wheels. However, we routinely strip the chrome plating alternative know as PVD which does not strip easily. It took an overnight strip, typically 12 hours or so to get most of the PVD coating off. We would either restrip and fallout again or eventually start placing the stubborn one in B-17. We used a drum to manually drip wheels in one at a time to both meet the OSHA spec in rlation to air quality in methylene chloride applications and to minimize safety incidents. <br /><br />The effectiveness of the Greensolv rapidly went down with our increased stripping volume as expected. The cost was rather high combined with shipping to replenish the tank. We then made a decision to go with General Chemical's WheelStrip 4028 which is a very similar product to the greensolv. Basically the same thing but with much strong smell, you could not easily walk in the room without a respirator any time the tanks were opened. There was a large amount of the solids that were suspended in the liquid that you have to monitor and decide when to change the bath completely which is not cheap. It is a dissolver so it also generate quite a bit of sludge at the bottom of the tanks that must be cleaned out frequently. We didn't have any inline filtration but that would have been the best option. <br /><br />Continuing down the path of increasing thru-put and improving safety we just recently switched to another product from General Chemical - Stripoxy. It is water based, has almost no smell but it not nearly as stong as any of the others we have tried. <br /><br />Currently investigating a switch to using the B-17 in larger volumes as it really does a fantastic job. As mentioned above, this is not for amateurs. It is extremely dangerous and very easy to get burned. I have seen people just get a few drops from rinsing the wheels off. OSHA also requires air quality testing to be completed once per year as there are standards for allowable air quality. We have had to add upgraded exhausts and poke-yokes to minimize injury potential. <br /><br />The b-17 can also be disposed of as non hazardous waste for about $1 per gallon which is way cheaper than anything above.

Blasting takes significantly longer unless you have a serious compressor and media blasting setup. However, if you must do without stripper, it is possible to get by with blasting alone. It just gets frustrating when you get a defect when powder coating. Blasting off powder coat takes a very long time so it is highly beneficial to have a powder coat stripper available in those situations. <br /><br />As far as blasting, outgassing, and re-blasting, this would only need to be done if the item is cast aluminum, cast iron, etc. or if it has spent a long time in a dirty/greasy environment. If you only blast once, make sure that you do it AFTER you outgas the part. Sandblasting should be the last step before powder coating.

I have read so many things about stripping and blasting (with this site being the best/most detailed & clear) my head is spinning. I have a large amount of bicycles that I'm restoring (stripping & powder coating), some are steel and some aluminum. I've used strippers in the past but moving forward my preference would be to not use them for all the downside reasons listed in the article, Stripping Powder Coat. <br /><br />My goal is quality and because I have several bikes, I'm trying to nail down an efficient and results based process. That said, I guess my question(s) would be, does blasting the original paint (instead of using stripper) still need to be followed by outgassing and then blasted again? Or can I blast then outgas and then thoroughly clean?<br /><br />thanks a lot!Joehttps://www.blogger.com/profile/02722631362558762154noreply@blogger.comtag:blogger.com,1999:blog-6576346347573188227.post-74778952086103952832016-07-22T09:57:44.382-07:002016-07-22T09:57:44.382-07:00After sandblasting, only handle the part with clea...After sandblasting, only handle the part with clean gloves.
