What's the difference between Wood Glue, Polyurethane Glue and Cyanoacrylate Glue?

Polyvinyl acetate – or PVA

Glue is typically what is referred to as carpenter’s glue or wood glue. PVA is basically an odorless and colorless bonding agent that has no dangerous fumes while it dries clear. It is safe to handle with bare hands and does not bond well to skin. These qualities make it perfect for use in a wide variety of bonding, especially in the woodworking shop.

PVA glue is a good to use with wood or plastic products because, in most cases, it dries clear and is easy to apply. It’s adapted easily and dries quickly. Any surplus or squeeze out must be wiped away as soon as it is applied because it can be difficult to remove once it is dry without damaging the wood underneath. Wipe it away with a "DRY" cloth or paper towel because moisture is not good for the bonding process.

PVA glue is generally inexpensive and a fairly long shelf life. It comes in both white and yellow coloring, and each have recommendations for their use. Typically, yellow tinted PVA glue is more water resistant and used more for outdoor items; however, it is not always completely clear when it dries. White PVA glue on the other hand is recommended more for indoor use because it is not water resistant. Dampness and humidity tend to weaken it over a period of time.

Polyurethane Glue

Most polyurethanes are thermosetting polymers, or thermoset plastic that becomes rigid and set when heated. Often room temperature is enough to provide the heat necessary to set thermosetting adhesives. The adhesive is applied as a liquid to one surface and water to the other surface. Once they come in contact and room temperature, Heat is absorbed which powers the chemical reaction, expanding the glue to make a strong network of chemical bonds.

Cyanoacrylate or CA Glue

CA or Super Glue is an acrylic resin that uses water moisture to speed the curing process. While Polyvinyl glues rely on the lack of moisture, CA and Polyurethane glues rely on it to cure. Usually, the natural moisture in air is enough for the CA glue to harden. Using an accelerator will speed up the process on the surface. CA glue works best on porous materials such as soft woods, and it will bond to any porous materials, especially your skin. It's very porous and with the moisture in your skin, bonding will happen very quickly (don't ask how we know that.) Acetone works well as a Debonding agent and it will dry your skin out as it removes oils and moisture from where it is applied. You will usually find it in "Thin", "Medium" and "Thick" Viscosities. CA glue has very strong fumes so please use in well ventilated area and never use a face shield that pulls air in and blows it across your face (it won't be good.)

Wood Glue

Water based adhesives, reliable adhesive for woodworkers that when they are cured are water resistant or waterproof. Premium glue formulas are used by carpenters and hobbyists alike. They use adhesive that woodworkers and carpenters alike find easy to use and have a water cleanup. Woodworkers and Carpenters trust for their permanent bond glue joints in their woodworking projects with benefits of an easy, creates a cross linking or bonding. Gorilla wood or any of the Titebond premium wood glues give your woodworking projects superior strength indoor or outdoor. Reliable glues offer the benefits of bond-to-bond superior holding, formula creates a cross glue premium formula. Super Glue or CA Glue is used to fill gaps where small cracks have occurred. Wood glue can also be used as a craft glue or filling gaps. Wood glue is an aliphatic resin that was once made from Horse Hide and that is where the name Hide Glue came from. No matter what type of glue you are using, it usually has a 24-hour cure time and creates a permanent bond.
