THPE 1,1,1-tris-(p-hydroxyphenyl)ethane 27955-94-8 ChemFirst Crosslinking / Coupling / Curing Agents Epoxy (EP) ADHESIVE Phenol, 4,4’,4’’-(ethylidene)tris CFEM’s THPE is a high purity, commercially available tri-functional phenolic. Used as a crosslinking or branching agent in various polymer applications, THPE can enhance key properties including adhesion, hardness, heat resistance and solvent resistance. THPE applications include use in polycarbonates, epoxies, adhesives, coatings, and antioxidants. Branched polycarbonates derived from THPE are high molecular weight thermoplastic materials that can be fabricated into films or sheets or blow molded to prepare structured containers. THPE can also be derivatized through esterification and etherification. Epoxy resins (tris-glycidyl ether) prepared from THPE are suitable for applications such as castings, laminates, composites and coatings requiring high mechanical strength and chemical resistance. Epoxy coatings and polymers cured with THPE exhibit excellent heat distortion temperatures, and chemical and solvent resistance. THPE modified formulations enhance the properties of high temperature adhesives, aerospace composites, laminates, and harsh environment applications. THPE is also available as a low metals (ppb) electronic grade material (THPE-E) suitable for use in photoactive compound (PAC) and PWB applications. High purity, tri-functional phenolic. Used as a crosslinking or branching agent in various polymer applications. Enhances key properties including adhesion, hardness, heat resistance and solvent resistance.
