Today, the production of decorative pieces based on transparent turpentine resin has developed considerably. The widespread use of epoxy resins has led to a variety of epoxy resins.
Turpentine Resin Benefits
Different gum turpentine resins are used in painting in order to develop mediums to paint and varnish. They are of several types: natural (mastic, dammar, copal, amber, shellac, rosin, sandarac), synthetic or alkyd.
Resins are natural substances secreted by certain plants. They are slightly amber and dissolve easily in alcohol or other solvents. They produce a solid and very filling film.
For mediums and oily varnishes, hard resins, soluble in oil, are chosen. They offer a shiny, adherent and very solid film.
The copal resin is of strong color, therefore avoid cold and light colors. It garnishes very well and gives very hard and shiny varnishes and mediums. Its disadvantage: the film can become brittle and darken as it ages.
For lean mediums and varnishes, soft resins, soluble in cold in a solvent, are used. They bring shine and increase transparency. They are particularly appreciated for glazes. But with age, they tend to turn yellow and become insoluble.
- The putty resin was Rubens’ favorite. It is the basis of thixotropic mediums-gel. It gives very beautifully, hard and shiny varnishes and mediums. But they turn yellow over time.
- The dammar resin, which appeared later, is appreciated for its weak coloring. It gives a supple, nervous, filling film. It is also much more economical than the putty resin to which it is close.
Global Turpentine Resin Trades
There are three types of transparent epoxy resins available in the poly composite store:
The first type of transparent epoxy resin is used to make decorative pieces such as rhinestones, jewelry, and ornaments. This resin boils easily due to its low viscosity (thinness). This resin dries faster than the second type of resin. This type of resin has a 50% hardener and is suitable for work with a maximum thickness of one centimeter.
The second type is intended for the manufacture of bulky and thick parts (such as epoxy tables combined with wood). Therefore, since the baking process of the second type of resin is slower and does not produce much heat during baking, this resin is used in cases where the volume and thickness to be applied in one step are high. The turpentine uses up to a thickness of about 4 cm in the cold season and about 2 cm in the hot season can be applied in one step. This type of resin is very thin and very easy to bubble. If small pieces are made with this resin, drying will take a long time. This type of resin has a 40% hardener.
The third type is suitable for abstract work, painting on canvas and certain jewelry to create a dome shape on the surface. Due to the high concentration of this resin, the color flow on the canvas is reduced and therefore the color control will be easier. This type of resin has a 50% hardener.
