How do I get rid of Macropoxy?
Remove all oil and grease from surface by Solvent Cleaning per SSPC-SP1. For better performance, use Commercial Blast Cleaning per SSPC-SP6/NACE 3, blast clean all surfaces using a sharp, angular abrasive for optimum surface profile (2 mils / 50 microns).
What is sweat in time for epoxy paint?
In fact, many epoxy materials have what is known as an “induction time,” or “sweat-in time,” where the coating is mixed and allowed to react for a period of time (e.g., 30 minutes) so that cross-linking of the components can initiate prior to application of the product.
What is gel time for epoxy?
Gel time should occur shortly (relatively speaking) after a resin’s pot time expires. For example, the Resin Obsession super clear resin’s pot time is 20 to 25 minutes. Its gel time occurs between 30 and 40 minutes after mixing.
What is epoxy blushing?
After application and during the curing (drying) process, a solvent-free epoxy resin releases a blush to the surface called Amine Blush. This blush is known to appear as a wax-like film that sits on the surface of the cured epoxy resin.
Why does my resin look oily?
Sometimes when resin is left to cure in cold conditions, the surface can develop a greasy film from the amines in the hardener. This film rapidly clogs sandpaper. The best thing to do if you detect this greasiness is wash it with warm water mixed with a small amount of dishwashing detergent.
Does epoxy resin catch fire?
Epoxy resin kits are made with chemicals that are not combustible. Unlike other resin products, like alcohol inks for resin and aerosol resin mold release, resin kits do not pose a risk of starting a fire if exposed to heat.
How toxic is epoxy resin?
Just as with poison ivy, the irritation can be mild or severe, acute or chronic. Inhaling concentrated epoxy vapors, if done frequently or for long periods, can irritate your respiratory tract. Exposing sensitive skin areas, like the eyelids, to highly concentrated epoxy vapors may cause itching and swelling.
