What is one benefit of using skin coats in lamination?

• A. They enhance color options
• B. They reduce overall weight
• C. They improve blister resistance
• D. They speed up curing time

Answer: (C)

Using skin coats in lamination primarily improves blister resistance. Skin coats are thin layers of resin applied to the surface of laminate materials before the main lamination process. These coats help seal the surface, minimizing the entry of moisture and air. Prolonging the exposure of the underlying layers to moisture can lead to blisters, which are caused by vapor bubbles forming under the surface, ultimately compromising the integrity of the composite material. By providing a smooth, sealed surface, skin coats effectively prevent the formation of these blisters, enhancing the durability and longevity of the laminated structure. This contributes to the overall performance of the composite material, particularly in applications where moisture resistance is crucial, such as in marine environments. While other options such as enhancing color options, reducing overall weight, and speeding up curing time may have their own advantages in certain contexts, they do not address the primary functional benefit of skin coats as it relates to combating blister formation. Thus, the emphasis on blister resistance positions it as the most relevant and significant benefit in the context of lamination.
