Q1: What are the primary application areas for ETERSET 2343?
A: ETERSET 2343 is widely used in fiberglass-reinforced plastic (FRP) manufacturing, including corrosion-resistant tanks and pipes, marine components, automotive body parts, and structural panels. Its balanced reactivity and mechanical performance make it especially suitable for spray-up and hand lay-up processes.
Q2: How should ETERSET 2343 be cured, and what catalysts are recommended?
A: ETERSET 2343 is typically cured using organic peroxides such as methyl ethyl ketone peroxide (MEKP) at ambient or elevated temperatures. Catalyst dosage depends on formulation requirements and processing conditions, but is generally adjusted to achieve a workable gel time while ensuring full crosslinking. Always conduct small-scale trials to optimize cure schedule for specific equipment and part geometry.
Q3: Is ETERSET 2343 compatible with common fillers and reinforcements?
A: Yes — ETERSET 2343 demonstrates good compatibility with standard mineral fillers (e.g., calcium carbonate, talc), glass fibers (chopped strand mat, woven roving), and low-profile additives. For optimal dispersion and interfacial adhesion, surface treatment of fillers or use of coupling agents may be beneficial depending on final performance targets.
Q4: What storage conditions are required to maintain resin stability?
A: Store ETERSET 2343 in tightly sealed containers at temperatures between 15°C and 25°C, away from direct sunlight, heat sources, and strong oxidizers. Prolonged exposure to elevated temperatures or contamination with accelerators or inhibitors can reduce shelf life or impair curing behavior.
