Description

1,3-Propanediol, 2,2-Bis(Hydroxymethyl)-, Polymer With (Chloromethyl)Oxirane, 2-Propenoate is a specialized polymer derived from the reaction of a polyol with epichlorohydrin and acrylic acid, resulting in a versatile reactive intermediate. This compound is valued for its ability to introduce cross-linking sites and enhance the mechanical and chemical resistance properties of final polymeric materials. It is primarily sought by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composite manufacturing.

Application

• As a cross-linking agent or reactive diluent in high-performance thermosetting acrylic and epoxy resin systems.
• Key intermediate in the synthesis of UV-curable resins for coatings, inks, and 3D printing materials.
• Modifier for adhesives and sealants to improve flexibility, adhesion, and chemical resistance.
• Component in the production of fiber-reinforced composites for automotive and aerospace applications.
• Building block for specialty polyols used in polyurethane foams and elastomers.
• Used in formulations for industrial maintenance coatings and corrosion-resistant linings.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Production follows strict protocols to guarantee batch-to-batch consistency in functionality, viscosity, and reactive group content. Certificates of Analysis (COA) detailing key parameters such as acid value, epoxy equivalent weight, and viscosity are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is light-sensitive (store away from light). For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
