Q1: What is the primary function of YD-115G in epoxy formulations?
A: YD-115G functions as a reactive diluent and viscosity modifier, enabling improved processability—especially in casting, potting, and coating applications—while maintaining good crosslink density and thermal stability after cure.
Q2: Is YD-115G compatible with standard amine and anhydride curing agents?
A: Yes, YD-115G demonstrates broad compatibility with common aliphatic and aromatic amines, as well as cyclic anhydrides, supporting flexible formulation design across ambient and elevated temperature cure schedules.
Q3: How does YD-115G affect the mechanical properties of cured epoxy systems?
A: When used at typical dosage levels, YD-115G helps retain tensile strength and glass transition temperature (Tg) while reducing brittleness—contributing to enhanced impact resistance and dimensional stability in finished parts.
Q4: Can YD-115G be used in low-VOC or high-solids epoxy systems?
A: Yes, YD-115G is a low-volatility, non-reactive-diluent alternative that supports VOC reduction strategies and is well-suited for high-solids and solvent-free formulations without compromising reactivity or final film integrity.
Q5: What handling precautions are recommended for YD-115G?
A: As with most epoxy resins, standard industrial hygiene practices apply: use in well-ventilated areas, wear appropriate PPE (e.g., nitrile gloves and safety goggles), and avoid prolonged or repeated skin contact to minimize potential sensitization risk.
