Types of Glue

September 19th, 2011 Tools

Glue can help you fix a wide variety of problems involving many different materials as long as you choose the right kind. Here's a list of the main categories of glue and how they work to create such a strong bond.

Water-based glue. When the water evaporates from this solution, the remaining material is left over to adhere to whatever it's touching. This is the most commonly used glue, but not always the strongest.

Moisture cure glue. This variety chemically reacts with moisture in the air or on the bonded surface to form a strong polymer layer. Silicone and polyurethane are the most widely used compounds, and they're best for jobs that involve caulking or sealing.

Cyanoacrylate glue. You might recognize this fast setting paste as crazy glue. A super strong plastic layer is formed when it reacts with moisture on the exterior of the object it's applied on.

Thermal glue. These binding products are heated to a liquid state before they are applied. When they cool down and dry, they become hard again. Waxes and hotmelt adhesives fall into this category.

Two-part glues. Two or more ingredients within the glue chemically react to form a cross-linked bond. The most common mixtures are epoxies, silicon varieties and acrylic blends. They're often expensive, but they're also among the strongest types of glue.

Ultraviolet glues. This option cross-links to form polymers when exposed to U.V. light. The connection can achieve full-strength in seconds, which makes this group perfect for quick bonding. Acrylic varieties are the most common.

These glues can help you stick things together in any type of job. Just be careful of where you apply it, because some of these varieties are strong enough to cause issues if you accidentally touch them!
