Types of Glue for Balsa Wood
Molding and Trim Glue
Use molding and trim glue if you are planning on adhering casing, baseboards, dado rails, and other similar trim walls. Molding and trim glues are specifically formulated to stick porous and semi-porous material really well.
Because molding and trim glues are designed for vertical use because they have a strong initial track and almost adhere to materials immediately. They also have an open time of around 5 minutes.
Melamine glue has a strong initial tack and an open time of around 5 minutes. The melamine glue is also specifically formulated to bond nonporous materials such as vinyl, melamine, high-pressure laminate.
Moreover, melamine glue can adhere metals to porous surfaces like chipboard, MDF, and wood. Melamine glue doesn’t require any special storage as it can be stored at room temperature. The application also isn’t complicated at all since it does not require any heat to be applied in order for the glue to start curing.
The official name for super glue is cyanoacrylate glue. Because most super glues stick instantly, it is required to stick both materials right away as the curing time of super glues is normally within less than 10 seconds.
The cyanoacrylate glue is also capable of bonding both non-porous and porous surfaces, making them perfect for putting metal bandings and decoration to wood. And because they do a good job of sticking materials fast, woodturners like super since they do a good job of attaching sacrificial pieces of wood and filling gaps and crack.
Cold Press Veneer Glue
Cold press veneer glues are specifically formulated for veneering. If you are looking for glue that will bond real wood veneers to a porous substrate such as wood, then cold press veneer glue is the perfect type of glue.
As seen in its name, cold press veneer glue does not require heat to cure and can be stored at room temperature.
Keep in mind that even though most veneer glues are PVA-based, cold press veneer glues will not bleed through tiny holes in open-grained woods. Open time of cold press veneer glues are around 15 minutes, allowing woodturners to easily reposition when needed.
Because of the cold press veneer glue’s composition, they are only suitable for veneering, so be mindful of the material you will use before choosing cold press veneer glues.
Polyurethane glue is an excellent all-purpose glue as it bonds almost any material. Once the adhesive dries, it becomes solvent resistant and water-resistant.
Because of their nature, polyurethane glues are perfect for output use. One thing that separates the polyurethane glue from other PVA-based glues is it foams up and expands when curing. The expansion process makes the polyurethane glue superior to PVA-based glues.
Unlike instant super glue, polyurethane glue has an open time of around 10 to 15 minutes, giving users an adequate amount of time for assembly. When clamping materials bound by polyurethane glues, make sure to clamp them for about 1 to 2 hours.
The curing time of most polyurethane glues will take around 24 hours.
How to Properly Put Wood Glue on Balsa Wood
Things to Consider when Looking for the Right Glue
When shopping for the right type of glue, you need to consider the following features to make sure the wood bond together effectively. Considering the fact that there is an overwhelming number of options in the market, knowing what factor to look for will ensure you the best output.
Some glues are more expensive than others but it doesn’t mean that the most expensive one is always the best choice. Come up with a price to know how much you should spend.
Apart from the price, the bond or hold strength is yet another thing you should check. Different glues are suitable for various types of bonds. Some adhesives can form a strong, permanent bond, while other adhesives allow joined surfaces to be removed or repositioned at a later time.
For example, aliphatic resins and PVA offer a stronger bond than polyurethane glues when putting together long grain to long grain woods. However, the adhesive strength is not the only factor that is critical to creating a very solid bond.
You see, even though you are still using the world’s strongest adhesive, the bond between two surfaces will still fail if the adhesive does not bond to the substrate or the surface.
Furthermore, water-based adhesives are normally used for laminating but are cost-effective alternatives to resins. Other adhesives can be melted or softened endlessly by heat or set by cooling to reposition or aid computer product builds.
Adhesives that share many characteristics as traditional glue sticks and bulk hot melt are commonly known as PUR or Polyurethane hot melt. A good example of PUR hot melt is a glue stick, which is dispensed in a traditional glue gun that offers some additional bonding attributes that fit various applications.
Drying Time or Curing Time
Curing time or drying time is the time it will take for the adhesive or glue to dry fully. Apart from the surface or type of substrate being glued, there are other factors that influence the curing time such as humidity and heat.
Depending on the type of glue will be how long it will take for the glue to dry completely. Heat and high humidity are among the factors that can affect the glue’s curing time, which can either shorten or lengthen the curing time.
Apart from the environment, the curing time also ranges greatly from a few days to several days, depending on the type of adhesive.
It is also important to consider the temperature at which the adhesive will be exposed to or can endure. Moreover, the temperature at which the adhesive is stored is also just as important.
There are a handful of environmental conditions that could potentially affect the adhesive’s cure process. One of the most important things that can directly affect the curing process is temperature. Even the slightest change in temperature can have an integral effect on cure speed or even affect the adhesive’s storage life or its overall performance.
Note that there are thermosetting adhesives such as formaldehyde resins, phenolic, and melamine, which can tolerate extreme temperatures. On a similar note, silicone adhesives are notable for having a high degree of flexibility and very high temperature-resistant, making them perfect choices for plumbing and marine applications.
Mind the Humidity
It is also important to check the humidity of the area where the adhesive will be applied on as too much humidity can cause the adhesive to become foamy in appearance or too soft in appearance.
To make sure that the adhesive will not change shape or strength, always check if it has a humidity range so that the bond strength will not be impacted negatively when applied on the surface.
A glue’s open time refers to the time of the glue coming out of the bottle before it begins its cure process. The open time is the maximum amount of time you have to assemble the parts when adhering to two surfaces.
Make sure to always check this ahead before putting things together so you will have an idea of how much time you have to clamp or stick two materials together.
