Abstract

Claims10
A plasticized sulfur composition, having superior resistance to crazing and cracking when coated on a surface, consisting essentially of at least 75 weight percent sulfur, 5 to 20 weight percent of a solid filler;
- and from 0.2 to 5 weight percent of a sulfur plasticizing compound selected from group consisting of esentially linear alpha-monoolefin having 6 to 14 carbon atoms and mixtures thereof.
A plasticized sulfur composition, having superior resistance to crazing and cracking when coated on a surface, consisting essentially of at least 75 weight percent sulfur;
- 5 to 20 weight percent of a solid filler;
- 0.2 to 5 weight percent of a sulfur plasticizer selected from the group consisting of an essentially linear alpha-monoolefin having 6 to 14 carbon atoms and mixtures thereof and from 0.1 to 2 weight percent of an auxiliary sulfur plasticizer selected from the group consisting of organic compounds having an acidic hydroxyl group and mixtures thereof.
