DOWSIL 732 Multi-Purpose Sealant General Industrial Bonding & Sealing Solution
Product Introduction of DOWSIL™ 732 Multi-Purpose Sealant
Basic Product Attributes
DOWSIL™ 732 is a general-purpose, one-part silicone adhesive/sealant with an acetoxy cure system. It cures at room temperature upon exposure to atmospheric moisture. Available in white, black, clear, and aluminum colors, it features a non-sag paste consistency for easy application.
Product Overview
DOWSIL™ 732 cures into a tough yet flexible rubber with excellent adhesion to substrates like glass, metals, and engineering plastics. It operates stably from -60°C to +180°C (black version up to +205°C), with short-term peaks at +230°C. Compliant with MIL-A-46106 and FDA 177.2600, it is suitable for food-contact applications.
Key Features
- Electrical Properties: Dielectric strength of 21.6 kV/mm and volume resistivity of 1.5×10¹⁵ Ω·cm.
- Mechanical Properties: Tensile strength 2.3 MPa, elongation at break 540%, Shore A hardness 25.
- Curing: Skin-over time 7 minutes; full cure (3mm depth) in 24 hours.
- Compatibility: Releases acetic acid during cure; may corrode sensitive metals.
Applications
Applications include industrial sealing/bonding (e.g., electronics encapsulation, automotive parts, HVAC systems) and FDA-compliant food processing equipment. Its weather resistance makes it ideal for outdoor construction joints.
