Red Seal Cabinetmaker Practice Exam

Which type of adhesive is known for its strong bond and flexibility in cabinetmaking?

1. PVA (polyvinyl acetate)

2. Polyurethane

3. Epoxy

4. All of the above

The correct answer is: All of the above

In cabinetmaking, the choice of adhesive is crucial for ensuring that joints hold securely and can withstand various stresses. All the options listed—PVA, polyurethane, and epoxy—are known for their strong bonding characteristics, but each has unique attributes that contribute to their flexibility and suitability in different applications. PVA, or polyvinyl acetate, is a common adhesive used in woodworking due to its ease of use, strong bond, and flexibility. It is water-based, which allows for easy cleaning and application, and it dries clear, making it aesthetically pleasing for visible joints in cabinetry. Polyurethane adhesives are known for their exceptional strength and versatility. They can bond a variety of materials, including wood, metal, and plastic, and are resistant to water, heat, and chemicals when fully cured. This type of adhesive expands as it cures, filling gaps and creating a very strong bond, making it ideal for applications where movement or stress may occur. Epoxy is a two-part adhesive that also provides a strong bond and is highly resistant to environmental factors. It cures to a rigid state, which can be beneficial in certain applications where stability is essential, though it is generally less flexible than the other two options. However, it can still accommodate some degree of movement
