Material & construction: Silicone elastomer; one-part formulation; paste consistency; room temperature/humidity cure system; white color; specific gravity 1.35; viscosity: paste.
Risk reduction/compliance benefit: High elongation and green strength support durable adhesion to a wide range of substrates; non-flowing formulation helps maintain placement during application.
What is this DOWSIL RTV Silicone Adhesive-Sealant used for?
This DOWSIL one-component RTV silicone adhesive-sealant is designed for durable bonding and sealing of modules and multi-component assemblies. It is commonly used in electronics assembly and industrial manufacturing where flexible sealing and reliable adhesion are required.
How does this adhesive-sealant cure?
This product features a moisture-curing system that reacts with ambient humidity at room temperature. It forms a flexible silicone elastomer without heat or mixing, simplifying processing and enabling convenient curing in standard production environments.
What makes the non-flowing paste consistency beneficial?
The non-flowing paste formulation helps maintain placement after application, reducing sag or movement on vertical or complex surfaces. This controlled consistency supports precise bead application and improves reliability during bonding and sealing of assembled components.
What performance properties support durability?
The adhesive-sealant offers 400% elongation, 320 psi tensile strength, and a Shore A hardness of 37. These properties provide flexibility and strength, allowing the cured material to absorb movement, vibration, and thermal expansion while maintaining adhesion.
How long does it take to become tack-free?
At 25 °C, the material becomes tack-free in approximately 25 minutes. Full cure time varies with joint thickness, humidity, and environmental conditions, but the room-temperature curing system enables efficient processing without specialized equipment.
