Types of Resins
Resins can be broadly classified into two types:
- Natural Resins: These are substances that are produced by plants, particularly coniferous trees. Examples include amber, copal, and rosin.
- Synthetic Resins: These are man-made substances that mimic the properties of natural resins. Examples include polyester, epoxy, and silicone resins.
