Resinous refers to something that has a sticky or gooey consistency, like a resin. It can be used to describe substances that are viscous or have a high adhesive property.

Examples of resinous substances include:

1. Tree resin: The sap-like substance that oozes out of trees when they are injured or under stress.
2. Pine resin: A type of tree resin that is commonly found in pine trees and is used for various purposes, such as making turpentine or varnish.
3. Epoxy resin: A synthetic resin that is used in a variety of applications, including adhesives, coatings, and composites.
4. Polyurethane resin: A versatile resin that is used in many different products, from foam cushions to coatings and adhesives.
5. Bakelite resin: A type of thermosetting plastic that was invented in the early 20th century and is still used today in various applications.

In general, resinous substances are characterized by their sticky or gooey texture and their ability to harden or set when exposed to heat or other chemicals.
