  • Gluing, sealing and coating compound
    Patent number: 6800682
    Abstract: A gluing, sealing and coating compound based on a styrene copolymer is characterized in that the styrene copolymer mainly contains styrene and in that it contains an aromatic compound-free polyalkylene oxide and/or its fatty derivative. These non-toxic plastcizers are easily tolerated and increase stickiness, elasticity and stretchability. These compounds are therefore suitable as binders for producing glues, coatings and sealing compounds.
