Hand Lay-up,spray Up Promote Thixotropic Unsaturated Polyester Resin

Unsaturated Polyester Resin (UPR) is a type of thermosetting polymer that is commonly used in the manufacturing of composite materials, such as fiberglass reinforced plastics (FRP). It is made by reacting an unsaturated polyester with a vinyl monomer, such as styrene, which acts as a cross-linking agent to form a three-dimensional network structure.UPR is a versatile material that can be formulated to have a wide range of properties, including high strength, durability, and resistance to corrosion, chemicals, and weathering.

UPR is typically supplied in liquid form and can be cured by the addition of a catalyst, such as peroxide, which initiates the cross-linking reaction. The curing process can take place at room temperature or at elevated temperatures, depending on the specific formulation and application requirements.

General resin has wide applicability and strong applicability. Its FRP products have good mechanical strength and high elongation, which are suitable for various hand lay-up ordinary FRP products.
