Adhesives for Wood Bonding

Adhesives for Wood Bonding

If you want to achieve success in your wood-working assignments you need to pay attention to the two most important items that ensure its success and they are the adhesive and the joinery that go into its making. As such there are a wide variety of Industrial Adhesives and it sometimes becomes quite overwhelming deciding the right one among them.

Certain factors have to be considered before choosing the adhesive for your wood bonding such as whether the application is going to be for the outdoors or the indoors; whether paint has to be applied on the completion of the project or whether it will be exposed to moisture and so on. A brief on some of the wood bonding adhesives that will go well with your project are listed below:

PVA Adhesives

PVA stands for polyvinyl acetate and includes yellow glue and white glue which are the most commonly used adhesives and best suited for all beginners. White glue works best on porous materials while yellow glue is more suited for interior wood working tasks. However, since these are not water proof they cannot be used for projects exposed to moisture. The greatest advantage of these is that they are stocked by your local store.

Epoxy Adhesives

The epoxy adhesive is comprised of two components, namely the hardener and the resin. Though both components are in liquid form, they harden when combined together due to the occurrence of a chemical reaction. The greatest advantage of the resultant epoxy is its resistance to moisture and works well even if there are gaps in the wood pieces that are to be bonded together. The time taken for curing varies with different epoxy formulations; however, those that take a longer time give a bond that also lasts for longer periods.

Polyurethane Adhesives

Polyurethane glue requires the presence of moisture for getting activated and once it is activated it swells and dries up. The drying process is very fast and the glue hardens on drying. It has the advantage of being waterproof; however, handling the dried polyurethane adhesive can give rise to problems with regard to finishing.

Cyanoacrylate Adhesives

Cyanoacrylate adhesives are sometimes referred to as super glues, power glues or instant glues. They are more used as a form of providing temporary bonding where the bonded pieces have to be cut off later. However, it has to be used carefully after knowing the instructions fully. They are not suitable for filling gaps in wood pieces like the epoxy adhesives and they have to be applied in thin layers if they have to cure properly. Its shelf life is lesser with it needing to be consumed within one month of its opening.

On a Concluding Note

The above brief gives an idea of the varied glues that act as good wood bonding adhesives. Making the right choice among them will depend on your requirements as stated above.
