Firstly at 50⁰C in a conventional reactor, mix the reactants (epichlorohydrin and bisphenol A) under a molar ratio of bisphenol A to epicholorhydrin 1:14, then raise the temperature to 115⁰C over a period of time of 30 minutes. Conduct this reaction under a nitrogen gas environment.
Secondly add an alkaline catalyst (2 moles of NaOH), as 30% aqueous solution, drop wise. This usually takes several hours. The rate of addition is maintained as such the reaction mixture does not change the colour when phenothalein (an indicator) is added.
Thirdly carry out the reaction for an additional 30 minutes and then wash out the excess catalyst.
Next raise the temperature to 130⁰C and remove water by decanting (The remaining liquid is dried with anhydrous sodium sulfate or other dessicant)
Lastly remove excess epichlorohydrin by vacuum distillation.

The best colorants to use for epoxy resin projects are typically liquid or powder pigments specifically made for resin. These colorants are designed to mix well with epoxy resin and create vibrant, long-lasting colors in your projects.
Epoxy resin can be used as a jointing compound.
To effectively color epoxy, you can use epoxy resin pigments or dyes specifically made for coloring epoxy. Mix the pigment or dye into the epoxy resin before applying it to your project. Experiment with different amounts to achieve the desired color intensity.
The chemical formula for epoxy resin is C15H16O2.
Epoxy floor coating systems are made up of two distinct elements: an epoxy resin and a polyamine hardener.
You can add color to epoxy resin by using resin dyes or pigments specifically made for resin. Mix the colorant into the resin before pouring it into your project mold. Experiment with different amounts of colorant to achieve your desired hue.
Yes, epoxy resin is considered a type of plastic.
Some creative projects that can be made using craft epoxy resin include jewelry, coasters, keychains, art pieces, and decorative trays.
To fix cracked epoxy resin, you can sand down the cracked area, clean it thoroughly, and then apply a new layer of epoxy resin to fill in the cracks. Make sure to follow the manufacturer's instructions for mixing and applying the epoxy resin.
