Art resin works through a simple chemical process involving the combination of two different liquids.
Essentially, art resin is a two-part epoxy that is mixed together to create a liquid. This mixture then undergoes a chemical reaction to become a solid.
The Two Parts
As the reference explains, art resin is a two-part epoxy. These two parts are:
- The Resin: This is typically the larger component.
- The Hardener: This is the catalyst that initiates the curing process when mixed with the resin.
Different brands and types of art resin will have specific mixing ratios recommended by the manufacturer. It is crucial to measure and mix these two parts accurately according to the instructions.
The Mixing and Curing Process
When the resin and hardener are combined in the correct ratio and thoroughly mixed, a chemical reaction called polymerization begins. This reaction causes the mixture to heat up slightly and transition from a liquid state to a solid state over time.
- Liquid State: The mixed resin and hardener are initially a liquid. As the reference notes, this liquid can be poured into molds, or used to coat surfaces. This is when the artist works with the material, adding pigments, glitters, or embedding objects.
- Curing State: Over several hours to days, the polymerization reaction continues, and the liquid mixture hardens completely.
- Solid State: The result is a hard, solid material. The reference states that it hardens to a clear, durable finish that resembles glass. This final cured state is waterproof, scratch-resistant, and provides a protective layer.
Key Steps in Working with Art Resin:
- Measure the two parts accurately according to the product's ratio.
- Mix thoroughly for the recommended time, scraping the sides and bottom of the container.
- Pour or apply the mixed resin within its working time (pot life).
- Allow the resin to cure fully in a dust-free environment.
To get started with resin art, as the reference mentions, you'll need a few basic supplies beyond the resin itself, such as mixing cups, stir sticks, safety gear, and the surface or mold you plan to use. The interaction between the resin and hardener is the core of how this versatile art medium functions.
