Good morning Jamie. I work at a CM and can offer some input on process flexability. I do not have any data on how reliable the coating is but I can say that they are both very difficult to control. Will you be selective coating or full coating? Ho

We have the same Asymtek machine, same Humiseal product, same bubbling issue on touch ups. Ive found that very light pressure and a thinner mixture usually yields good results for us. Generally I dip the brush in the mixture and let it drip near wher

Hello @ the specialists, we have a Nordson Asymtek SL940 to coat our pcb's. We can use the valves SC100 and SC400 for conformal coating applications. We use the Humiseal 1A33 as the conformal coating. Now we would like to use the standard 1A33 in th

Hello , We are using Kester 959T flux and we wish to purchase Aim Ws 716 flux, due to higher activity. We also use humiseal 1a33 for conformal coating. Is anyone using Aim flux and humiseal 1A33, are they compatible ? Thank you for info

Silicone contamination could appear as fisheyes or dark spots under UV light. 1A33 can be heat cured but is a single component oxygen cure coating - it needs a source of oxygen to cure. An unvented oven may slow or limit the cure. Check out the TDS

I am planning on trying to autospray CE 1155 using an SCS precision coat. Does anyone out there currently do this? If so, can you share any information and parameters such as mixtures, methods, head configuration, conveyor baking. ANY information
