5 Common Problems to Avoid when Working with Epoxy Resin
Epoxy resin is a chemical that exists in 2 parts. When you combine these parts the effect is a strong and clear adhesive. Epoxy resin has many applications which can include mold making, laminating and sealing external or internal fixtures. One main application is in the construction field where epoxy resin can be used as an insulator. There are some minor problems one can face when using epoxy resin and this article will point some of the most common out to you.
Epoxy resin is so powerful that very little is needed to make it work properly. It has to be applied to the surface in question in a layer nearly as thin as paint. This makes it incredibly difficult, even for those in the construction business, to apply epoxy resin by hand. It is a good idea to use epoxy resin in pre-measured application pumps. These pumps will also mix the correct ratio of epoxy resin with the catalyst. This method alone can negate many of the issues with epoxy resin that are listed below. Always remember to use very small amounts spread out along the surface.
Cloudiness when Epoxy Resin Hardens
Epoxy resin should dry clear but this can change if moisture is introduced to the resin or the surface where the resin is meant to be applied. So make sure that the surface is completely clean and dry. Also use an epoxy resin that is already mixed and inside a double-barrel syringe. Another instance of epoxy resin clouding is when you speed up the drying process using methods such as a hairdryer.
Hot Epoxy Resin
The chemical reaction between the catalyst and epoxy resin will cause it to heat up slightly as it bonds. This endothermic reaction is slight but will increase depending on how much epoxy resin you mix. Too much heat can cause chemical burns to the skin as well as the surface being bonded. The heat can also increase if the mix is wrong. It is incredibly important to be very careful when using the epoxy resin.
Bubbling and Deformities
When too much air is introduced to the epoxy resin bubbles can rise to the surface as the epoxy resin cures. Bubbles and deformities can also occur when it dries too fast at high temperatures. This is a reaction caused by excess heat as it cures. You can easily avoid bubbles and deformities if you use the epoxy resin during colder days or during the night.
Dullness after Curing
When using epoxy resin it will dry dull but you want it to shine like you've seen it shine previously. The truth of the matter is that epoxy resin does not dry shiny. Those who use epoxy resin professionally add a step to the process that they do not share. This step involves coating the epoxy resin with a clear coat enamel or some sort of polyurethane. This is applied once the epoxy resin has cured. Once you apply a thin coat of polyurethane you can buff it with a towel.
