Q1: What is the primary function of LH898-17N in polyester resin systems?
A: LH898-17N is a reactive liquid polyester resin designed to serve as a viscosity modifier and reactive diluent in unsaturated polyester (UPE) formulations. It helps improve processability—especially in casting, laminating, and pultrusion—while participating in the crosslinking reaction without significant volatile emissions.
Q2: Is LH898-17N compatible with common UPE resins and initiators?
A: Yes, LH898-17N demonstrates broad compatibility with standard orthophthalic, isophthalic, and vinyl ester-based unsaturated polyesters. It works effectively with conventional peroxide initiators such as MEKP and BPO, and does not interfere with typical gel time or cure profiles when incorporated at recommended levels.
Q3: How does LH898-17N affect final composite properties?
A: When properly formulated, LH898-17N contributes to enhanced flexibility and impact resistance in cured composites, while maintaining good mechanical integrity and thermal stability. Its low volatility supports reduced styrene emission during processing, supporting improved workplace safety and regulatory compliance in industrial settings.
Q4: What are the recommended storage and handling conditions?
A: Store LH898-17N in tightly sealed containers under cool, dry, and well-ventilated conditions, away from direct sunlight and strong oxidizing agents. Prolonged exposure to elevated temperatures or moisture may affect reactivity and shelf life. Always observe standard industrial hygiene practices—including gloves and eye protection—during handling.
