Q1: What is the primary function of ReforMax 420 in thermoset resin systems?
A: ReforMax 420 is a high-performance amine-based catalyst designed to accelerate the curing reaction of phenolic, melamine, and urea-formaldehyde resins—particularly in foundry binder applications—enabling faster mold hardening and improved green strength without compromising thermal stability.
Q2: Is ReforMax 420 compatible with cold-box and no-bake foundry processes?
A: Yes, ReforMax 420 is specifically formulated for use in both cold-box (amine-gas cured) and no-bake (self-hardening) resin systems. It delivers consistent reactivity and shelf-stable performance when blended with phenolic or furan resins under typical foundry processing conditions.
Q3: How should ReforMax 420 be handled and stored to maintain optimal performance?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and strong oxidizing agents. Ensure containers remain tightly closed after use to prevent moisture absorption and amine volatilization, which may affect catalytic activity over time.
Q4: Can ReforMax 420 be used in combination with other catalysts or additives?
A: ReforMax 420 can be co-used with certain latent accelerators or surfactants to fine-tune cure profile and flow behavior—however, compatibility testing is recommended prior to full-scale implementation, as interactions with acidic additives or metal-based promoters may alter reactivity or storage stability.
