Unsaturated resin is a common raw material for chemical production, which is widely used in various fields, such as coatings, adhesives, composite materials and so on. There are many upstream and downstream related products of unsaturated resin, and some of the main products will be described in detail below.

1. Upstream related products

(1) Styrene: Styrene is one of the main raw materials for unsaturated resins and is used to produce unsaturated polyester resins. Styrene is a colorless and transparent oily liquid with aromatic odor, flammable and toxic.

(2) Acrylic acid: Acrylic acid is also one of the important raw materials for unsaturated resins and participates in the synthesis of unsaturated polyester resins together with styrene. Acrylic acid is a colorless, transparent, pungent odor liquid, flammable, corrosive.

(3) initiator: initiator is the key raw material of unsaturated resin polymerization reaction, commonly used initiator benzoyl peroxide, lauroyl peroxide and so on. The initiator can initiate the polymerization reaction of the double bond in the unsaturated resin to generate the high molecular polymer.

2. Downstream related products

(1) Coatings: Unsaturated resin can be used as the main film-forming substance of coatings, and can be used in conjunction with other pigments and fillers to make coatings with various properties, such as anti-corrosion coatings, marine coatings, wood coatings, etc.

(2) Adhesive: Unsaturated resin can also be used as the main component of the adhesive for bonding various materials, such as metal, wood, glass, etc. Unsaturated resin adhesive has the advantages of high bonding strength and good water resistance.

(3) composite materials: unsaturated resin can be used as the matrix material of composite materials, and glass fiber, carbon fiber and other reinforced materials, made of a variety of high-performance composite materials, such as glass fiber reinforced plastic, carbon fiber composite materials.

In short, the upstream and downstream related products of unsaturated resins are very extensive, involving various fields, such as building materials, aerospace, automobiles, ships, etc. With the continuous development of science and technology, the application field of unsaturated resin will continue to expand.
