Question about epoxy
« on: December 27, 2019, 23:15:41 pm »
I designed a commemorative wedding plaque for my daughter using 1 line font supplied by cambam, thanks for that to whom it may concern. the epoxy is only .125 deep and just wondering about the drying time on this before i can go on with staining and clear coating?    CB attatched

If it's a two-part epoxy coating, it should be well-cured in 12 hours, and completely-so in 24.

Even so, it might require a "wipe-down" with a little acetone to remove any 'stickiness' on the surface, before you try to do subsequent finishes.

Some epoxies produce what is called an amine ‘blush’ on the surface. If I recall correctly you need to use ammonia to clean it off, acetone won’t do it.

Most epoxies have a set time marked on the packaging or in the instructions, but for full cure it takes atleast 24hrs.  Maybe longer if its in a colder environment. 
Getting started on CNC?  In or passing through my area?
If I have the time I'll be glad to show you a little in my shop.

HMM temperature in a cold shop would have to be taken into consideration, good point.
