Q1: What is the primary function of ARALDITE GT7072 in epoxy formulations?
A: ARALDITE GT7072 is a reactive liquid epoxy resin modifier designed to reduce formulation viscosity while maintaining good reactivity and contributing to enhanced flexibility and toughness in cured networks.
Q2: Is GT7072 compatible with standard amine and anhydride hardeners?
A: Yes, GT7072 is broadly compatible with common epoxy curing agents, including aliphatic and aromatic amines as well as cyclic anhydrides, and can be co-blended with solid or higher-molecular-weight liquid epoxy resins.
Q3: How does GT7072 influence the mechanical properties of cured epoxy systems?
A: When incorporated into epoxy formulations, GT7072 typically improves impact resistance and fracture toughness without significantly compromising thermal stability or chemical resistance—making it suitable for demanding structural and protective applications.
Q4: Can GT7072 be used in high-solids or solvent-free coatings?
A: Yes, its low volatility and reactive nature support its use in low-VOC and 100% solids coating and adhesive systems, where it helps achieve target application rheology and film formation characteristics.
