ortho polyester resin manufacturer in china-RealLand Composite Material

Product Description

Ortho Polyester Resin is designed for high performance composites with excellent mechanical strength, chemical resistance and heat resistance (operating temperature up to 120 °C +) . The low viscosity formula ensures efficient infiltration of the fiberglass, resulting in a smooth cured surface with few bubbles. Ortho Polyester Resin products meet ISO standards and are environmentally friendly (low styrene volatilization) , supporting customized weather, flame retardant or fast curing requirements.

Features & Applications

Ortho Polyester Resin Properties

Outstanding Mechanical Properties: Ortho Polyester Resin has high tensile strength and flexibility that allow it to be used for load-bearing structural components.

Chemical Resistant: Corrosion resistant to acid, alkali and solvent, developing good chemical environment.

Low viscosity, easy processing: High infiltration of glass fiber, low air bubble, suitable for hand lay-up, spray-up and pultrusion process.

Surface Smoothness: After curing, Ortho Polyester Resin has a very flat surface, which greatly reduces the follow-up sanding process.

Custom Options: Fast curing Ortho Polyester Resin, fire retardant (UL94 V-0), UV resistant or weather resistant.

Ortho Polyester Resin is widely used in fiberglass products, transportation parts, chemical equipment and electrical and electronic packaging and other fields, with excellent corrosion resistance and weather resistance.
