Synthetic glue can also stick both porous and non-porous materials. What is more, they become rock hard and would not shrink at any one time. If you need them for your sticking; you can always find them in tubes.
Then there are the polyester resins. They resemble epoxies but will not shrink easily. When they hardened, they are ideal for glass fiber.
Another widely used adhesive is the silicone. Silicones work best in high temperatures. They are also resistant to water and are often used for electric cabling.
There are also adhesives that are derived from parts of animals. Frequent ones are the glue cakes that are made from the hides and bones. Then there is the famous gelatin, an adhesive that is even used for cooking. You can use animal adhesive on fabrics, cards, and even papers.

They are applied or sprayed on the surface fast so that the droplets land on the intended surface before they dry up. Majority of these aerosols, adhesives are dispensed with the help of a spray gun or an aerosol can.
