Frequently Asked Questions about MT3821
Practical application and design questions — answered by SILITECH.
Permabond MT3821: 2:1 modified 2-component epoxy adhesive (thixotropic, black) for flexible bonding — pliable, excellent adhesion to nylon, ABS, and polycarbonate. Main applications: Flexible engineering plastic bonding, multi-material bonding with thermal expansion, vertical bonding.
Selection criteria: 1) Substrate (engineering plastics such as nylon/ABS/PC require modified epoxies like MT382), 2) Gap width (large gaps: thixotropic variants), 3) Flexibility (tolerance compensation: flexible variants like MT3821), 4) Mixing ratio (1:1 simple, 2:1 or 10:1 for defined properties), 5) Pot life (short for high throughput, long for careful processing). SILITECH provides consultation for selection.
Store in the unopened original container in a dry, cool place — Permabond adhesives typically between +5 and +25 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging. Store cyanoacrylates cool (ideally refrigerated) for maximum shelf life.
