cabosil is fumed silica and can usually be mixed as a thickening agent with resins such as polyurethane (clear awlgrip?), epoxy, and polyester/vinylesters.
Polyurethane isn't epoxy, but they're both resins. They're also both reaction copolymers--you get either one through a chemical reaction between two components. The difference is, epoxy contains epoxide and polyamine; polyurethane contains a complex alcohol (either a "diol" or a "polyol") plus an isocyanate.
Yes, you can,and it's very good for that use. However if the concrete is bare, you must apply an epoxy primer before the polyurethane finish.
Yes. Because a chemical bond is no longer possible because the epoxy coating has dried, a mechanical bond is required. This merely means that the cured epoxy must be lightly sanded before applying the next layer: the first coat should have a matt, nearly white finish.
Yes, you can on some one-part epoxies; however, be sure to check the data sheet for the epoxy. Most solvent based epoxies will act as a remover when placed over polyurethane.
You cannot harden it. Improperly mixed epoxy must be completely removed and replaced. Be sure to thoroughly mix epoxy before application.
From what I found is that its a type of oriental first name and the if you might be refering to araldite then its a company that does a range of jobs from engineering and structural epoxy, to acrylic, and polyurethane adhesives. The name was first used in 1946 for a two-part epoxy adhesive
It's glue that comes as a cylinder with one epoxy wrapped around the other. You cut off a slice and mix it in your hands.
No, Seal-Krete Epoxy-Seal is an acrylic-epoxy blend. By mixing 2 unlike resins (patio paint and Epoxy-Seal) the hard Epoxy-Seal acrylic-epoxy resins would become weak resulting in a coating failure.

You can apply "oil" based polyurethane over "oil" based enamel, you can also apply "water" based polyurethane over "water" based enamel, never mix the two, there's to much of a chance for problems.
