Vinylster Hand Layup resin
Description
R500 series is formulated from a high-performance vinylester resin designed for composite parts requiring enhanced mechanical and chemical resistance.
This resin provides excellent durability, easy handling, and controlled curing behavior, making it suitable for a wide range of hand lay-up and contact molding applications.
Its viscosity profile enables efficient reinforcement wet-out and uniform laminate consolidation, while improving resistance to water absorption and osmosis.
Product Characteristics:
- Easy handling for hand lay-up processes
- Excellent wet-out of fiberglass reinforcements
- Higher mechanical strength compared to conventional polyester resins
- Very good chemical and osmosis resistance
- Controlled gel time and consistent curing performance
- Good bonding between layers
- Suitable for pigmenting and gelcoat lamination
Primary Applications:
R500 series is recommended for the fabrication of composite parts requiring a high-quality surface finish, such as:
- Transportation components (rail systems, buses, specialty vehicles, etc.)
- Swimming pool manufacturing
- Marine and boat hull construction
- Water park structures and aquatic equipment
- Parts exposed to moisture or corrosive environments
Recommended Application Methods:
- Spray-up
- Hand lay-up
