Advantages and Disadvantages of Resin Casting
In resin chemistry and materials science, resin refers to a homogenous or nearly solid substance of synthetic or plant origin which is usually highly viscous. Resin is usually a combination of natural substances. Most commonly used in interior design, the beauty industry, medical, industrial, and home furniture industries, resin adds a certain glow to whatever it is that it is employed with. Used for everything from flooring to pool lining, resin adds a unique glow to whatever it’s used on. Glow in the dark resin has recently found its way into other arenas, most notably the automotive industry.
There are many types of resin. The most common types are polyester resin, liquid resin epoxy, hardener resin, epoxy resin, UV curing resin, and urethane resin. Depending upon the type of product, resin will be required in different amounts, mostly depending upon the properties of the final product. Polyester resin is the most common type and is usually sold as a powder, much like paint, in the same can as paint. Because of this portable nature, resin epoxy is often used to create a white finish on acrylic couches.
Because of its non-flammable nature, resin has been widely employed in making varnishes for decades. Over the years, its use as a manufacturing material in varnish has expanded to include more elaborate designs such as intricate swirls, multicolored sprays, and gold leaf imprints. It can be painted on and cured in the same can as other types of plastic materials, but because of its added stability, it has been utilized in building material rather than painting. The coating provides added protection against cracking, chipping, and general wear and tear. It is non-porous, so it cannot harbor bacteria and viruses like other plastics can.
Resin coatings provide a smooth, flat surface for painting, and they also have the ability to resist corrosion. This makes them ideal for industries that require a flat, smooth surface to work on. Unlike with paint, resin art has many benefits. For instance, it is stronger than both enamel and urethane, and it can be thinned just a fraction of the amount required for acrylic and other thinner coats. Plus, it is available in an infinite array of colors, allowing manufacturers to produce various effects for their products.
Another advantage of resin is the ease of its application. Unlike with acrylic and other materials, applying resin art is quick and simple. A brush or roller is needed for application, and a thick but flexible brush is ideal for getting into small crevices. A rubber mallet is used for breaking up the resin into various parts. A plasticizer is then used to add the color to the paint, and the entire surface is left to dry overnight. The next day, the painting surface is ready to use.
Resin is also known for its wide range of durability. While most other materials are susceptible to breakage during normal use, resin made plastics stay strong and can last longer than other plastics. As a result, they can be used for a lifetime. Many types of resin made compounds last up to 75 years or more when well cared for. Others can outlast most synthetic plastics.
There are some disadvantages to using resin casting as opposed to synthetic resin. First, it can be difficult to apply resin casting if it isn’t applied correctly. If the resin is applied too thick or too thin, it can easily fail to harden, creating large bubbles or cracks. On the other hand, although resin made synthetic resin can be thicker than natural resins, it can also be brittle and can be easily broken.
When it comes to determining whether a material is a resin made or synthetic resin, you can test it by applying an edge coat of one to two coats of a hardener. If the edge coat of hardener stays on top after applying the hardener, then you are dealing with synthetic resin. If not, then you are dealing with natural resin. To get the best effects from resin, you should use a hardener with a medium density.
