When considering the effectiveness of an epoxy adhesive, it is useful to analyze the general formulation of the compounds that constitute it. Epoxies are created by polymerizing a mixture of two starting compounds, the resin and the hardener. When resin is mixed with a specified catalyst, curing is initiated.
Spray Fabric Adhesive. Spray fabric adhesive is useful and neater to apply than glue, but not permanent if the fabric is cleaned by laundering or dry cleaning. Also, unlike the recommended glues, it has toxic fumes and must be used in a well-ventilated space.
A rub joint with liquid hide glue is not as strong as when hot hide glue is used, but it’s still useful in some circumstances. Pieces on the right side, with ragged edges, clearly show wood failure. As you move to the left, you’ll notice the smooth edges, which indicate glue failure.
Cyanoacrylate glue is the industrial name for what is commonly known as “Crazy Glue” or “Super Glue”. In fact, the term cyanoacrylate glue generally describes quick-bonding super glues. They can be used to combine anything from metal to plastic and even human skin.
White glues dry much softer than yellow glues and hence, are awful to sand. Over time this property can cause visual glue lines to appear with wood movement. The yellow glues are more brittle, but are very easy to sand. Strength is a non-issue because they are both much stronger than the wood, as mentioned.
