Goma-2 was a type of
high explosive manufactured for industrial use (chiefly mining
) by Unión Española de Explosivos S.A.
It was a gelatinous,
nitroglycol
-based explosive widely used within Spain and exported abroad.
It was used by ETA in the 1980s and 1990s.
There were two variants of Goma-2: Goma-2 EC and Goma-2 ECO. As of 2017, the manufacturer MAXAM Corp. S. L. has reformulated the Goma-type ammonia gelatine dynamites which are marketed worldwide under the new Riodin trade name.
Properties
Goma-2 explosive was a mixture of several chemicals:[1]
- Ammonium nitrate - 60–70%
- Nitroglycol - 26–34%
- Nitrocellulose - 0.5–2%
- Dibutyl phthalate - 1–3%
- Fuels - 1–3%
As with other commercial blasting explosives, detonators were needed to initiate a detonation (usually a
blasting cap
# 8).
Terrorist use
Goma-2 ECO was the explosive that was used in the
Operation Ogro to assassinate Luis Carrero Blanco
. The explosion was so powerful it threw Blanco's car over a five store building.
