What iIs MDF Glue
MDF glue is an adhesive for MDF consisting of long molecule chains called polymers. These polymer molecules give the glue the property of ‘cohesion,’ which is the ability to bind to itself. The bond between glue and wood is a different type of bond called ‘adhesion.’ It is based on the molecular attraction between the molecules of glue and wood.
In order for this bond to be sturdy and strong, the joint should be clear, snug, and gap-free. Some MDF glues also form mechanical bonding between the glue and wood fibers. However, the molecular attraction contributes more to the strength of the bond.
How Do MDF Glues Work?
All woodworking glues work in four different ways:
- White and yellow PVA or polyvinyl acetate glues cure when the solvent evaporates, leaving behind a solid glue line
- Two-part glues like plastic resin and epoxy-based glues need a chemical reaction to cure; the glue polymerizes or forms new polymers
- Third: some glues like hot-melt glue are thermoplastic in nature. This means they flow when hot and solidify when cooled
- Hybrid glues work through evaporation and a chemical reaction like the two-part glues
Different Types of MDF Glues for Woodwork
You’ve probably moved up and down in the aisle of a hardware store looking for the perfect woodworking glue. You may have had the following options at your disposal: white, yellow, plastic, resin, epoxy, etc. So, which glue is right for you? Here are some basic MDF glue types and their characteristics:
PVA or Polyvinyl Acetate
The white and yellow varieties of glues are PVA or polyvinyl acetate. Both are great for most indoor/exterior woodworking jobs. They are safe, easy to use, dry quickly, are non-messy, and also inexpensive.
All PVA glue types are an emulsion of polyvinyl acetate particles in water glues (chemical formula (C4H602)n). The tiny particles of PVA coalesce into a rubber-like solid to form a semi-transparent glue line. The clamping time for this type of glue is short, but it still needs at least 24 hours for the glue to reach its full strength.
White PVA glue is the original PVA glue. It is somewhat runny compared to yellow PVA glue. Yellow PVA glue is aliphatic resin glue. It is also a type of PVA glue, but it has been modified to give slightly different working characteristics compared to white glue. Yellow glue, as compared to white glue, is thicker, sands more easily, and is also more heat resistant.
Both yellow and white glue are equally likely to fail under wet conditions.
Plastic Resin Glue
These are also called urea-formaldehyde glues. Plastic resin glues are highly water-resistant, and experts recommend them for cabinetmaking, laminated countertops, cutting boards, etc. with plastic resin glues, you have to mix a powder with a catalyst like water or resin. The resulting glue forms a rigid plastic-like polymer bond, which is very strong and impervious to water. The powder in plastic resin glues comes in various shades of brown, so you can customize it to your wood’s color.
A downside to using this type of wood glue is the exposure to formaldehyde, which although negligible, could lead to skin irritation.
Epoxies are two-part glues that can be of the slow set or quick-set varieties. The quick-set epoxies can set anywhere between 1-10 minutes, and they also cure in a few hours. Slow-set epoxies could take 24 hours to harden and up to a week to cure.
