Dowsil 744 Circuit Board Component Bonding RTV Adhesive Sealant
Basic Properties
Dowsil™ 744 is a one-part, white, non-flowing RTV adhesive sealant designed for general-purpose bonding. With high elongation (590%) for stress relief, it cures at room temperature without mixing or ovens, and supports heat acceleration for faster production.
Product Description
Curing via ambient moisture (30–80% RH), it achieves >90% physical properties in 24–72 hours. With a 10-minute skin-over time (25°C/50% RH) and workable time of 10–120 minutes, it cures inward at 0.25 inch/7 days. Silicone chemistry ensures stability across -45°C to 200°C with dielectric strength (15 kV/mm), ideal for electronics requiring long-term reliability.
Characteristics
Beyond elongation, its tensile strength (2.7 MPa), tear resistance (20 N/cm), and low modulus (0.5 MPa) enable flexible bonding with minimal substrate stress. Shore A hardness 37 balances flexibility/support, while volume resistivity (5×10¹³ Ω·cm) ensures insulation. Adhesion to aluminum reaches 430 psi (substrate testing required), with 12-month shelf life (25°C).
