Eyelash Extensions Written Practice Exam

Which type of adhesives can be stretched, twisted, or squeezed?

1. Permanent

2. Elastomeric

3. Reactive

4. Hypoallergenic

The correct answer is: Elastomeric

The correct choice is elastomeric adhesives, which possess unique properties that make them notably flexible and adaptable. These adhesives can stretch, twist, and be squeezed without losing their integrity or performance. This flexibility is essential in applications where materials need to maintain adhesion despite movement or stress, such as in eyelash extensions where the natural eyelashes may flex. Elastomeric adhesives are designed to accommodate dynamic stresses while maintaining a secure bond, which is crucial for ensuring that eyelash extensions remain intact during regular wear. This quality helps in providing durability and comfort for the client. In contrast, permanent adhesives are generally designed for long-lasting adhesion but do not typically allow for movement without risking a bond failure. Reactive adhesives often require specific conditions to set and cure, making them less adaptable in situations requiring flexibility. Hypoallergenic adhesives focus more on minimizing the risk of allergic reactions rather than being stretchable or flexible. This highlights how elastomeric adhesives stand out in applications requiring both adhesion and resilience to physical manipulation.
