GASKETS AND OTHER PRODUCTS OBTAINED BY CO-DISPENSED COMPOSITIONS

摘要

A gasket (20) or other object comprising a core (27) and a flexible outer layer (24) prepared by co-­dispensing at a temperature of about 15 °C to about 30 °C, a core composition and an outer layer composition, wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein each component has a viscosity at 25 °C of less than 106 cps. The core and outer layer compositions are applied in a non-solid state. The outer layer is preferably at least a two reactive-component elastomer or foam. A method for producing a gasket or other object comprising co-dispensing a core composition and an outer layer composition at a temperature of about 15 °C to about 30 °C, wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein the composition has a viscosity at 25 °C of less than 106 cps.
