The chemical family of urethanes is known for _________.

1. high durability

2. low toxicity

3. excellent adhesion

4. flexibility

The correct answer is: excellent adhesion

The chemical family of urethanes is known for their excellent adhesion properties. This quality makes urethanes particularly valuable in various applications, including nail products. Their ability to effectively bond to surfaces allows for improved performance and longevity in nail enhancements, such as gels and polishes. This adhesive strength is crucial for ensuring that the products stay intact despite the normal wear and tear they may encounter. While urethanes do have other beneficial characteristics, such as being relatively durable and flexible, which contribute to their overall effectiveness in nail technology, the defining feature that sets them apart in this context is their superior adhesion. This property ensures that the products applied will adhere well not just to the natural nail but also to any additional products being layered on, enhancing the overall finish and durability of the manicure or enhancement.
