Summary: | The present invention provides a sulphur cement precomposition, comprising sulphur and at least a polysulphide-containing organosilane in an amount of at least 0.3 wt % based on the weight of the total composition, which polysulphide-containing organosilane is of the general molecular formula: (X3Si)mH(2n+l-m)Cn-Sa-Cn'H(2n'+l-m')(SiX'3)m' wherein a is an integer in the range of from 2 to 8, X and X' each are, independently, a hydrolysable group, n and n' each are, independently, an integer in the range of from 1 to 4, and m and m' each are, independently, an integer in the range of from 1 to (2n+1). |
