Advantages and disadvantages of fiberglass polyurethane coating

Advantages:

Good mechanical properties: Waterborne polyurethane resins can provide good mechanical properties, such as strength, stiffness, and durability, when combined with glass fibers.

Environmental friendliness: Compared to traditional solvent-based polyurethane resins, water based polyurethane dispersion do not contain organic solvents and are environmentally friendly.

Reduced energy consumption: The production process of waterborne polyurethane resins does not require high temperature drying, which can save a lot of energy.

Easy to use: Waterborne polyurethane resins can be used as single-component coatings without the need for matching components, making them more convenient and easier to use.

Disadvantages:

Higher cost: Due to the complex production process, the cost of waterborne polyurethane resins is relatively high.

Poor hydrolysis resistance: The stability of waterborne polyurethane resins in humid environments is inferior to that of solvent-based polyurethane resins, making them prone to foam, coating bubbling, and other problems.

Why choose waterborne polyurethane resins in the glass fiber industry?

Waterborne polyurethane resins have good environmental characteristics that conform to modern industrial environmental requirements.

The combination of glass fibers and waterborne polyurethane resins can improve mechanical properties such as strength, stiffness, and durability within a certain range.

Waterborne polyurethane resins can be used as single-component coatings, which are more convenient and easier to use.

Waterborne polyurethane resins can provide a wider range of choices, allowing the glass fiber industry to select waterborne polyurethane resins with different properties and characteristics as needed to better meet customer requirements.
