Hello: We have a coating operation the requires the curing of the product at 395 C. The present lubricant is applied as a grease and eventually (3 months) turns to a powder that can contaminate our product. This requires an extensive and expensive oven cleaning approximately every 3 months. Does...
Hello: Due to print specifications, we are required to grit blast our substrates prior to powder coating. The powder is a mixture of teflon and SiC. After curing, some rolls have a defect that we call grit or protrusions. Analysis of defects shows grit or SiC. Has anyone seen this type of...
Hello:
How are you? I was wondering if anybody is aware of the change in surface finish (Ra and Rz) to an aluminum surface after anodizing? Prior to anodizing, the surface finish will be submicron - will it change after anodizing?
Thank you,

Hello:
We would like to measure the hardness of an adhesive, preferably after it has been welded to a substrate. After welding, the adhesive is approximately .001" thick and .004" wide. Thank you and have a great day,

Hello:
I am trying to find some articles that reference the usage of shields, robbers and thieves. These would be utilized in the electroplating/electroforming of nickel in an effort to improve the deposit uniformity. I would appreciate the address of any sites that have this information. Thank...
Hello: I have an application where we need to measure the internal bubbles of a translucent cylinder. Normally, we would cross section the part - however, for this application, we cannot cut or destroy the part. We were trying to use a microscope but it is hard to get below the surface to see...

Is there a colormetric or spectrophotometric method or equipment to classify corrosion? We have steel parts that have been coated with electrolytic zinc. Some parts have white corrosion, some have rust. We would like to classify the corrosion and lack of corrosion my...
Hello;<br>
Is corrosion measureable/quantifiable? Also, is there a recommended minimum thickness of zinc on steel for parts in a high temperature and high humidity environment for extended periods?<br>
<br>
Thank you for your time,<br>
