¿Cuál es el tipo de resina para mis proyectos?

This is a question that may arise when working with these materials, how can we decide which one is right for us? Which one will we make the best use of?

We have the well-known Epoxy Resin , as we already know, it is a type of thermosetting plastic, which transforms from a liquid to a solid state when a hardener is applied. But knowing this resin, what are its advantages :

  • Transparency level
  • Durability
  • Combination with a wide variety of materials

Among its disadvantages we have:

  • Low resistance to UV rays.
  • You need to mix the composition
  • Long drying period.

What pieces can we work with this resin?

  • combine materials
  • Create large parts
  • Obtaining transparent finishes.
  • small size parts

On the other hand, we have the UV Resin , it is a type of resin that, as its name indicates, performs the curing process using a UV light. This resin is used for small-sized crafts. Among its main advantages we have:

  • fast drying
  • no need to mix
  • Due to its rapid drying, it works as glue.

It also has its disadvantages , such as:

  • Care must be taken at the time of application to avoid bubbles.
  • Very thick coats are not recommended because it may not dry properly.

What job can we work with this resin?

  • small size parts
  • Jewelry and costume jewelery
  • Use it as glue among other resins

The next resin is the polyurethane resin , or known as " white resin", this resin is composed of polyurethane, so when mixing, normally 1:1, it takes a white place. Among its advantages we have:

  • Low density, that is, fewer bubbles.
  • fast drying
  • UV resistance
  • Can be painted.

Its disadvantages are:

  • Not as hard as epoxy
  • It wears down molds due to its density level.

What job can we work with this resin?

  • small size parts
  • Jewelry and costume jewelery
  • Decorative pieces for furniture

And finally, we have Polyester Resin , it is a type of resin that has a hardener, unlike the previous ones, it requires an amount of 1-3% of hardener with respect to the total amount of resin. It is the cheapest but at the same time the most toxic.

Its main advantages are:

  • Low cost
  • Quick drying


  • strong odors
  • Gray

What job can we work with this resin?

  • Hollow pieces, due to its rapid drying, it manages to adhere to the molds .
  • Repair of industrial parts.
