3M Scotch-Weld EC-3515 B/A FR | Flame-Retardant Two-Part Epoxy | 1:1 by Volume | 0.47 to 0.50 g/cm³
Product Description
A flame retardant two part epoxy, EC-3515 B/A FR from the 3M Scotch-Weld line needs no oven: it keeps, mixes and cures at ordinary room temperature. Honeycomb edges get sealed with it, voids get filled, and it doubles as an abradable compound, hardening into a strong low density solid inside 48 hours at 24 °C. Base colour is blue or black, accelerator is white, so a uniform mix can be judged by eye.
Structure
| Component | Material / Construction |
| Backing | none – two-part compound, base and accelerator supplied as dough |
| Adhesive | flame retardant epoxy base with modified amine accelerator |
| Release Liner | none – bulk compound |
