FAQs
What type of product is LOCTITE SI 595?
LOCTITE SI 595 is a one-component RTV silicone adhesive and sealant that cures on exposure to moisture. It forms a flexible, durable rubber seal, ideal for bonding and sealing applications across various industries like automotive, electrical, and HVAC.
What surfaces and materials is it compatible with?
LOCTITE SI 595 bonds and seals a wide range of materials, including metals, glass, plastics, ceramics, and composite materials. Its versatility makes it suitable for use in electrical, automotive, and industrial applications where reliable bonding and sealing are required.
What temperature range and durability properties does it offer?
LOCTITE SI 595 can withstand temperatures from -65°F to +450°F (-54°C to +232°C). It resists aging, UV light, ozone, weathering, and thermal cycling, ensuring long-lasting performance in harsh environmental conditions, making it suitable for both high and low-temperature applications.
How is the product applied and what is its cure time?
LOCTITE SI 595 is a thixotropic paste, meaning it won't sag during vertical or overhead applications. It cures at room temperature, becoming tack-free in 45 minutes and fully cured within 24 hours, depending on humidity and temperature, ensuring quick and effective bonding.
What are the typical physical properties like hardness, elongation, or tensile strength?
LOCTITE SI 595 has a Shore hardness of approximately 14A, with an elongation of around 275% or more. Its tensile strength is about 120 psi, providing strong adhesion for sealing applications that require flexibility and durability under various stress conditions.
