Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues.
Many different brands, types, and colours are commercially available. Binders include lacquer, water-base, and linseed oil. Some woodworkers make their own putty using fine sanding dust (not sawdust, which is too coarse) with wood glue or a wood finish such as shellac.

The left component is Epoxy Base Resin and the right one is Epoxy Hardener. Both are to be mixed thoroughly in equal quantity to get epoxy putty. Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application.
While J-B Weld Original epoxy dries to a dark grey color, [10] J-B Weld's ClearWeld epoxy dries clear. [11] Although its bond is not quite as strong as the Original's (3900 psi vs. 5020 psi), [12] ClearWeld is often preferred when appearance is an important consideration. [13]
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
Resorcinol glue, also known as resorcinol-formaldehyde, is an adhesive combination of resin and hardener that withstands long-term water immersion and has high resistance to ultraviolet light. [ 1 ] [ 2 ] The adhesive, introduced in 1943, has been popular in aircraft and boat construction.
After evaporation of the solvent, a solid compound is formed. Chemical bonds are also important in certain adhesive / substrate combinations, for example when bonding glass using silicone adhesives, wood using polyurethane adhesives and aluminium using epoxy adhesives. Chemical bonding leads to significantly higher adhesion than physical bonding.
Water-based fungicides, because they are water-based, can be washed away in time if the wood they are applied to keeps getting wet. This is another reason why it is important to fix leaks, thus keeping the wood dry in an alkaline environment, and seal the wood (especially the end grain) to prevent ongoing exposure to hungry spores.
