Abstract
Water and a hydrated salt are both present to reduce the flammability of a flammable resin system, e.g. a capsule having two compartments each containing an interactive component and for use in e.g. a mine.
Claims13
A capsule containing in separate compartments the interactive components of a self-setting composition, one component comprising an unhardened resin and the other component comprising a hardener therefor, the capsule being rupturable to release the interactive components to intermix them and form the self-setting composition, at least one of the components beig flammable, both free water and hydrated salt being present, the free water or the hydrated salt or both being located in at least one of the components prior to the interaction thereof, the concentration of the free water and the hydrated salt being sufficient to supress the flame of the flammable component but still permitting the set composition to have a strength which exceeds 20 Newtons/mm.sup.2.
A self-setting composition comprising first and second components, the first component comprising an unhardened resin and the second component comprising a hardener therefor, the two components being intermixed to form said self-setting composition, at least one of the components being flammable, both free water and hydrated salt being present, the free water or the hydrated salt or both being associated with at least one of the components prior to intermixing, the concentration of the free water and the hydrated salt being sufficient to suppress the flame of the flammable component but still permitting the set composition to have a strength which exceeds 20 Newtons/mm.sup.2.
