Epoxy resin: Tricks and fine workmanship

Epoxy resin was originally designed for use in industrial applications. Now many who are engaged in handicrafts, repair use it. It is also used to fill the floor.

The complexity of the epoxy is that you need to prepare it properly. Epoxy resin during the solidification can not be anything to soften. Therefore, the original instructions, see the packaging, so as not to make mistakes.

When working with epoxy it can be seen that it hardens slowly. To expedite this process you need to heat the mixed curing agent and epoxy resin. For small compositions of this can be done with a hair dryer. You can pour the finished structure on the foil and heated from below with a lighter. If the curing agent are mixed better (than is specified on the package), the composition will solidify too quickly. But worsens the structure in excess of the hardener.

If bubbles appear on the surface can blow through the tube to the place, and the bubbles burst. When heated in a water bath or by using a hair dryer resin becomes liquid for a while and the bubbles burst. But you should not overheat. The process of hardening is reduced.

You can make the solution more liquid can add a plasticizer (dibutyl phthalate).

First, the epoxy is mixed with a plasticizer, and only then is diluted hardener. Dibutyl phthalate is not necessary to add more than 10% of the total weight of the epoxy.

The solution has excellent penetrating ability. Keep this solution may be a long time in a closed boat, alone.

If not want to epoxy resin yellowed by heat or sunlight in the finished product, it is necessary to select a resin with UV - filter.

After contact with the hands, must be immediately wiped with a cotton pad arms (dipped in alcohol). Then just rinse your hands with soap and water.

Epoxy can be dyed by ink pens or simple gel, stained paint (not water based), or brilliant green spec. toners (epoksikon).

Silverfish (aluminum powder) attached with epoxy silver color and electrical conductivity.

If you want to get the black color, then add the resin, graphite powder. But this option is not suitable for the products to be stored under the sun. For use white flour, gypsum, alabaster or toothpowder.

If dissolved much glue, it is possible to put the ready adhesive (glass to a bowl) in the freezer for a day and the solution dries.
