Bostik FP 370 Fireseal Mortar
Bostik FP 370 is a gypsum-based powder mortar enriched with perlite and inorganic compounds. When mixed with water, it forms a highly insulating fire sealant for openings around cables, pipes, and ductwork in fire-rated walls and floors. The mortar hydraulically expands (~1 %) for a tight seal, supports loads without reinforcement, and maintains acoustic performance. Fire protection is certified up to 4 hours according to EN 1366‑3 :contentReference[oaicite:17]{index=17}.
Storage & Stability
Store in unopened bags in a dry place between +5 °C and +30 °C. Shelf life is at least 12 months according to NL TDS, with no specific limit if stored properly :contentReference[oaicite:18]{index=18}.
