SEM 39683 Grey Self Etching Primer - 15.5 oz.

Q: Why does SEM not recommend applying color directly to this primer?

This is an etching primer. I, used it on Magnesium after etching with Borax and baking soda mixed. After drying I, used this prime 4 light coats over 4 days 1200 wet sand paper. I, then coated with primer for the paint ! 3 coats wet sad 3 coats of final coat rubbed out with fine polishing compound.I, did this project in Nov 19. So far so good.

Q: What type of paint can be applied on top of the primer? any paint? sprays? water based? oil based? are there any restrictions?

I would recommend staying with the same brand of paint for both primer and top coat. Although the SEM primer seems to work well with most top coats, I had a bad experience using it with a Rustoleum top coat. After priming bare aluminum with the SEM self-etch and letting it cure overnight, I applied a Rustoleum top coat. Within a few hours both the primer and the top coat pealed off. I spoke with the the SEM and the Rustoleum technical folks but neither knew exactly what caused this. Both, however, recommended sticking with the same brand for primer and top coat. I would recommend doing some test sprays, letting the primer cure the recommended length of time before applying the top coat. Note that the SEM self-etch is acetone based, and this might cause a problem with topcoats that use other bases, especially if the SEM has not been cured long enough.

Q: I have stripped aluminum bare. self etching primer, then primer, then top coat? are all these these paints made by sem?

All i can tel u that the image is sem

Q: Is this the same as zinc chromate primer?

I do not have the can anymore. So I cannot read the ingredients. However I do not think it contains zinc chromate...which is used for marine and auto applications. This stuff works great for bonding to bare aluminum parts that will need to be painted. Hope this helps.
