陶氏 3-8219
描述信息
DOWSIL 3-8219 RF Silicone Foam is a reduced-flow medium hardness product, primarily developed as a dispensed ‘foamed-in-place’ gasket material for the automotive and industrial assembly & maintenance industries.
When the A and B liquid components are thoroughly mixed in a 1:1 ratio by volume, the product will expand and cure to a foamed elastomer in approximately 10 minutes at room temperature.
This foam has a fine cell structure and functions as a seal or gasket where long service life, chemical resistance, good weatherability and low compression set are required.
