Differences Between Polyurethane and Polycrylic
1. Chemical Composition
Polyurethane is a synthetic resin made by combining a polyol and an isocyanate. The resulting chemical reaction creates a tough, durable material that is resistant to abrasion, chemicals, and water. Polycrylic, on the other hand, is a water-based product that contains acrylic polymers.
2. Appearance And Texture
Polyurethane tends to have a thicker, more viscous texture than Polycrylic. It also has a slightly yellow or amber color, which can slightly alter the appearance of the vinyl decal. Polycrylic, on the other hand, dries clear and has a thinner, more watery consistency. It typically does not alter the appearance of the vinyl decal as much as Polyurethane.
3. Durability And Longevity
Polyurethane is known for its excellent durability and longevity. It can withstand heavy wear and tear and is particularly resistant to scratches, stains, and water damage. It is also more UV-resistant than Polycrylic, making it a better choice for outdoor use. Polycrylic, while durable, is not as resistant to scratches or UV rays, and may need to be reapplied more frequently.
4. Application Process and Tools
Polyurethane is oil-based and requires solvents for clean-up. It is best applied with a natural bristle brush or a foam brush, and may require multiple coats to achieve the desired level of protection. Polycrylic is water-based and can be cleaned up with soap and water. It can be applied with a synthetic brush, a foam brush, or even a sprayer. It typically requires fewer coats than Polyurethane to provide adequate protection.
It’s important to consider these differences when deciding which product is best for your vinyl decal. Depending on your needs and preferences, one product may be better suited than the other.
Similarities Between Polyurethane and Polycrylic
While there are differences between the two products, there are also some similarities.
- Both are clear finishes: Polyurethane and Polycrylic both dry clear, allowing the vinyl decal underneath to remain visible.
- Both can be used to protect vinyl decals: Both products are designed to provide a protective layer over the vinyl decal, preventing scratches and other damage.
- Both provide a glossy finish: Both Polyurethane and Polycrylic will leave the vinyl decal with a glossy finish.
Considering the similarities and differences between these two products, it’s important to make an informed decision on which one to use on your vinyl decal. Let’s now look at the vinyl decal itself and explore what it is, its applications, as well as its benefits and drawbacks.
