陶氏 3-8209
描述信息
DOWSIL™ 3-8209 Silicone Foam is a low to medium hardness product, primarily developed as a dispensed ‘foamed-in-place’ gasket material for the automotive and industrial assembly and maintenance industry. 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.
产品应用
- DOWSIL™ 3-8209 Silicone Foam is designed to be dispensed and cured directly on parts to form an integrated compression gasket.
- Typical applications include automotive parts, housings for electric devices, exterior lighting and domestic appliance components.
