Zusammenfassung:The degree and reproducibility of cohesive bonding between gum-type organosiloxane elastomers cured by a platinum-catalyzed hydrosilation reaction and organic polymer substrates are increased when the composition used to prepare the elastomer contains an amount of silanol-functional polydiorganosiloxane sufficient to impart an activity number of at least 40 to the polydiorganosiloxane gums present in said composition.
