- rosin
Rosin is a specific form of resin — pine resin that has been heated to remove the volatile oils. Used on violin bows and in soldering. Not a general substitute for 'resin'.
- gum
Unlike resin, gum dissolves in water and comes from plants such as acacia. Used in food and medicine as a thickener. Resin is water-resistant and typically water-insoluble.
- sap
Sap is the watery, nutrient-carrying fluid inside a living tree. Resin is a separate, thicker defensive substance the tree produces only when injured. Do not treat them as the same thing.
用法筆記
Natural resin comes mainly from conifers such as pine and fir, and from some tropical trees. Synthetic resins — like epoxy, polyester, and acrylic — dominate industrial applications in adhesives, coatings, and composite materials. The uncountable form is far more common; countable uses (e.g. 'a resin' meaning a specific type) appear in technical contexts.
