Loctite SI 595 RTV Adhesive Silicone

Loctite SI 595 RTV Adhesive Silicone (300ml) is a medium-viscosity clear acetoxy silicone sealant engineered for maximum efficacy in bonding and sealing mechanical assemblies. This industrial-grade adhesive permanently seals out moisture and contaminants, preventing costly leaks and corrosion caused by mechanical shock, vibration, or environmental exposure. Whether you are securing trim bonding or sealing ductwork, vents, flues, doors, and windows, this premium RTV silicone compound provides a robust, leak-proof seal on all common substrates—including ceramic, composite, glass, metal (aluminum and steel), and plastics.

Why Choose Loctite SI 595?

• Superior Adhesion and Flexibility: Cures on exposure to moisture in the air to form a tough, flexible, silicone rubber seal that fills large cracks and seams without slumping.
• Broad Material Compatibility: Engineered for excellent bonding properties across diverse surfaces like glass, metals, ceramics, and composites (not recommended for concrete).
• Extreme Environmental Resistance: Formulated to withstand extreme temperature cycling, UV light, and ozone without hardening, shrinking, or cracking.
• Heavy-Duty Reliability: Provides dependable electrical insulation and protects delicate leads and components from mechanical shock.
• Food Equipment Certified & Safe: Certified to ANSI/NSF Standard 51 for use with plastic materials and components in food equipment environments up to +204°C, and classified by Underwriters Laboratories Inc.® (E257711).

Technical Specifications

• Product Type: Acetoxy Silicone Vulcanizing Compound Paste Sealant
• Strength: Medium (Thixotropic, non-slumping paste)
• Color: Clear
• Container Size: 300ml
• Certifications: ANSI/NSF Standard 51, Underwriters Laboratories Inc.® E257711

Simple Application Instructions

1. Clean: For optimal performance, bond surfaces must be completely clean and free from grease, oil, or older sealant residues.
2. Apply: Apply the thixotropic paste to the target area. Because moisture curing begins immediately upon exposure to the atmosphere, parts to be assembled should be mated within a few minutes after dispensing.
3. Assemble: Assemble the components as required. Excess material can be easily wiped away using non-polar solvents. Note that full performance properties will develop over a 72-hour cure cycle.

Frequently Asked Questions (FAQ)

What is Loctite SI 595 used for?

Loctite SI 595 is a 1-part RTV acetoxy silicone paste designed for potting, coating, and sealing applications. It is specifically formulated to prevent moisture infiltration and protect mechanical or electrical assemblies from environmental stress, mechanical shock, and severe weather conditions.

Can Loctite SI 595 be disassembled?

Yes, cured silicone can be mechanically removed or peeled away by cutting the flexible bond with a sharp knife or razor edge. Any residual film or thin layers can be softened and wiped away using appropriate non-polar solvents.

Does Loctite SI 595 work on all materials?

Yes, Loctite SI 595 offers robust performance across a vast array of surfaces, including metals (aluminum and steel), glass, ceramics, composites, and most plastics. It is not recommended for use on concrete surfaces.

Is Loctite SI 595 safe for food equipment environments?

Yes, Loctite SI 595 is certified to ANSI/NSF Standard 51, making it approved for use with plastic materials and components utilized in food equipment applications, provided the operational temperature does not exceed +204°C.
