]]> Comment on Venting Your UV Light-Curing Process by Dan Hanscom http://www.dymax.com/blog/?p=478&cpage=1#comment-621 Dan Hanscom Thu, 17 Feb 2011 15:14:10 +0000 http://www.dymax.com/blog/?p=478#comment-621 Mr. Westre Thank you for your opinions and comments. First of all, OSHA places the responsibility of safety within the walls of your facility on your company not the supplier. While the end user may consult with suppliers for guidance or additional information, if available, most suppliers cannot anticipate what occurs at their customer's facilities. Therefore, when determining whether to exhaust or not, the 8 factors mentioned in the post (<a href="http://www.dymax.com/blog/?p=478" rel="nofollow">http://www.dymax.com/blog/?p=478</a>) are critical in assisting with this assessment. Due diligence is important to provide management with supporting data to justify whatever decision is made by the end user. Odor should not used as an indicator of a hazardous exposure. Our sense of smell is acute and highly receptive. This means, that in some cases, we are able to detect odors well below exposure limits where it poses no risk to the employee. See <a href="http://www.dymax.com/blog/?p=149" rel="nofollow">http://www.dymax.com/blog/?p=149</a> for more information on this subject. I'm not sure what you meant by species. If you are referring to the chemical composition, we do know what is coming off of the curing product during “normal” use. While we can make an assumption that you are using it normally, this would only be an assumption and not based on data. Under normal use, what is being emitted during polymerization is a small percent of the more volatile components within the finished product. These components can be found on the material safety data sheet (msds) which can then be used to provide guidance on the hazards associated with the 727BT and how to protect your company’s employees. If you need a more current msds, please let us know and we will send it to you. The “smoke” you see coming off the product, in this case, is a sign that a polymeric exothermic reaction is occurring but not all light curing materials exhibit this phenomena to the extent that fumes are visible. <a href="http://www.dymax.com/blog/?cat=20" rel="nofollow">http://www.dymax.com/blog/?cat=20</a> please review the blog written on this subject. Ultimately, by conducting a hazard assessment of the process you should be able to determine what factors are contributing to the condition experienced by your employees. You did not mention what other tasks they are performing, if there is any other chemicals (i.e. cleaning solvents, lubricants, etc.) they may be exposed to during the course of a day, whether the room is climate controlled or any other factors that may impact this situation. In order for us to provide better assistance, a greater understanding of your process is needed. If you need local assistance, please provide your contact information and we can make sure someone contacts you. Sincerely, Dan Safety Manager Mr. Westre

I completely disagree with your approach. As the manufacturer of the chemical you should (and perhaps are required)to know what species are being created during its normal use. Are you saying that you do not know what species are being emitted into the atmosphere? I would think that an air sample over the curing gel run through a GCMS would tell you. A visible 'smoke' or mist rises from the 727BT maskant. In fact it is an easy way to tell that the material is curing. The odor is very strong and in a 20x20 room with cross draft ventilation at the work tables, the chemicals in the air are sufficient to impair the workers. The curing station is in the corner. We installed ventilation directly over the curing area because the workers were getting buzzed on the fumes. So maybe you want to look into that a little more.

If not a direct humidity effect, could it be a static electricity effect? I have a static bar prior to the coating station. It seems that I have noticed a weaker bond in low humidity.

]]> Comment on Light/UV Curing Through Polymers by Kyle Rhodes http://www.dymax.com/blog/?p=872&cpage=1#comment-498 Kyle Rhodes Fri, 24 Sep 2010 20:37:10 +0000 http://www.dymax.com/blog/?p=872#comment-498 If you have a acrylic fiber of 3 mm diameter, you can shine a light down from one end of the fiber to the other, but internal reflection within the acrylic will cause the light to stay within the fiber, and it will not go through the side wall of the fiber (for example - it will not come out at a 90 degree angle). Anytime you have a interface between plastic and air, or plastic and water, or air and water, the angle of incidence becomes important. If you shine a flashlight at a pool from right above it, the beam will enter the water and bend slightly. If you shine a flashlight at a pool while at a shallow angle (almost horizontal), the light beam will instead bounce off, and not go into the pool at all. This is the same for light shining through plastic rods or fibers. There are tricks to use to get light to come out the side, but this is more of a question for an Optical Engineer. If you would like to contact our Application Engineering group by phone or <a href="http://www.dymax.com/tech_support/tech_support.php" rel="nofollow">email</a> to describe what you are trying to do - we may be able to help further.
