Loctite 435 Instant Adhesive 20g

Loctite 435 Prism Instant Adhesive 20ml is a rubber-toughened, ultra-clear ethyl-based instant adhesive engineered for maximum efficacy in high-performance bonding. This industrial-grade adhesive permanently bonds components together, preventing costly assembly failures caused by high impact, shock loads, or severe peel forces. Whether you are securing small-to-medium parts or handling general assembly tasks, this premium cyanoacrylate provides a robust, leak-proof seal on all materials—including difficult-to-bond, porous, absorbent, and acidic substrates.

Why Choose Loctite 435 Shock & Impact Resistance?

• Toughened & Flexible Bond: Formulated with rubber reinforcement to offer increased flexibility, high peel strength, and superior resistance to shock loads.
• Versatile Material Compatibility: Provides excellent adhesion across a wide spectrum of substrates, including metals, rubbers, and plastics.
• Porous Surface Specialty: Engineered to deliver rapid, reliable bonding on challenging porous or absorbent materials like wood, paper, leather, and fabric.
• Acidic Surface Performance: Maintains highly effective curing speeds and bond strength even when applied to notoriously difficult acidic surfaces.
• Humid Environment Resilience: Demonstrates excellent, long-lasting resistance and structural integrity in humid and damp operational environments.

Technical Specifications

• Product Type: Ethyl-based Instant Adhesive (Cyanoacrylate)
• Strength: High (2700 psi Shear Strength on Grit Blasted Steel)
• Color: Ultra Clear / Colorless
• Container Size: 20ml
• Certifications: Qualified to Henkel's ISO 10993 Test Protocol for use in the medical device industry

Simple Application Instructions

1. Clean: For optimal results, clean all internal and external bond surfaces with a Loctite cleaning solvent to ensure they are clean and free from grease, then let dry.
2. Apply: Apply several drops of the liquid adhesive to one of the bond areas. For peak performance, ensure a thin bond gap (ideally around 0.05 mm). Do not use tissue or brushes to spread the liquid.
3. Assemble: Assemble and align the parts within 10 to 20 seconds. The formula will begin curing rapidly once confined between the two mating surfaces via atmospheric moisture. Allow 24 hours for full chemical/solvent resistance to develop.

Frequently Asked Questions (FAQ)

What is Loctite 435 used for?

Loctite 435 is a high-strength ethyl-based instant adhesive designed for bonding small to medium-sized parts. It is specifically formulated to prevent components from failing or separating due to high impact, severe shock loads, dynamic stress, or vibration.

Can Loctite 435 be disassembled?

No, not with standard mechanical hand tools alone. Because Loctite 435 forms a highly rigid, permanent polymer matrix, disassembly typically requires the application of localized high heat (exceeding its 70 - 160 °F thermal threshold) or specialized chemical cleanup solvents like nitromethane or acetone to dissolve the bond line.

Does Loctite 435 work on porous or acidic surfaces?

Yes. Loctite 435 offers robust performance across a vast range of materials. Unlike traditional instant glues, it is highly effective on both porous/absorbent substrates (such as wood, paper, leather, and fabric) as well as challenging acidic surfaces.

Is Loctite 435 safe for medical device environments?

Loctite 435 is qualified to Henkel's ISO 10993 Test Protocol. This means it is approved as an eligible choice for selection and assembly in the medical device industry, provided regional approvals are confirmed with your local Technical Service Center. Note that it is not recommended for pure oxygen, oxygen-rich, chlorine, or strong oxidizing systems.
