TUFFALLOY 4270 is a series of Liquid Molding Compounds with thermoplastic properties such as high impact, high heat distortion, and low viscosity. This unique chemistry developed by Hapco to meet today's market demands for prototype and low production parts needs.

THE TUFFALLOY 4270 Series are available in (4) speeds.

The user has the ability to use different speeds of TUFFALLOY 4270, typically using a slower speed initially and increasing to a fast set, 1 minute working life.

PROCESSING:
  • TUFFALLOY 4270 Series can be pressure cast, vacuum cast, or open cast.
  • For best results, TUFFALLOY 4274/75 should be used with Hapco's metering/dispensing equipment, RAPIDFIL, MINI FIL, and RAPIDSHOT.
