SL 502 High-Strength Transparent Glue for Metal and Plastic

Overview

SL-502 is a premium two-component epoxy adhesive engineered for high-performance bonding of metal and plastic substrates. Designed for industrial and commercial applications, this transparent glue combines exceptional strength with optical clarity, making it ideal for scenarios where structural integrity and aesthetic appeal are equally critical. Formulated with advanced polymer technology, SL-502 ensures long-lasting adhesion even under extreme environmental conditions, including temperature fluctuations, moisture exposure, and chemical contact. Its versatility and reliability have made it a preferred choice across industries such as automotive, electronics, aerospace, and consumer goods manufacturing.

Features

1. Dual-Curing Mechanism: Achieves initial tack within 10–15 minutes and full cure in 24 hours (at 25°C), ensuring rapid assembly without compromising bond strength.

2. High Tensile Strength: Delivers a tensile strength of ≥35 MPa, suitable for load-bearing applications.

3. Optical Clarity: Maintains 95% light transmittance post-cure, ensuring invisible seams for seamless finishes.

4. Temperature Resistance: Stable across a broad range (-40°C to +150°C), suitable for both cryogenic and high-heat environments.

5. Chemical Resilience: Resists degradation from oils, solvents, and weak acids, ensuring durability in harsh conditions.

6. Low Volatile Organic Compounds (VOCs): Compliant with international environmental standards (ISO 10993, ROHS, REACH).

Benefits

· Enhanced Productivity: Fast curing reduces downtime, accelerating production cycles.

· Cost Efficiency: Eliminates the need for mechanical fasteners (e.g., screws, rivets), reducing material and labor costs.

· Aesthetic Superiority: Transparent bonds preserve product design integrity, ideal for consumer-facing applications.

· Durability: Withstands thermal expansion, vibration, and stress, extending the lifespan of bonded components.

· Eco-Friendly: Low VOC emissions align with global sustainability initiatives and workplace safety regulations.

Applications

1. Automotive: Bonding interior trim, sensors, and lightweight alloy components.

2. Electronics: Securing transparent panels, display modules, and plastic housings in devices.

3. Aerospace: Assembling composite materials and cabin interiors with strict weight and safety requirements.

4. Consumer Goods: Repairing or fabricating transparent plastic items (e.g., eyewear, aquariums).

5. Industrial Equipment: Sealing and reinforcing metal-plastic hybrid structures in machinery.

FAQ

Q1: What is the recommended surface preparation for SL-502?

A: Surfaces must be clean, dry, and free of grease. For metals, lightly abrade with 120-grit sandpaper; for plastics, use isopropyl alcohol to remove contaminants.

Q2: Can SL-502 bond dissimilar materials (e.g., aluminum to polycarbonate)?

A: Yes, SL-502 excels in bonding metal-plastic hybrids due to its optimized adhesion chemistry.

Q3: Is the adhesive suitable for outdoor use?

A: Absolutely. Its UV-resistant formula prevents yellowing or brittleness under prolonged sunlight exposure.

Q4: How should unused adhesive be stored?

A: Store components A (resin) and B (hardener) separately in cool, dry conditions (10–25°C). Shelf life is 12 months unopened.

Q5: Can SL-502 be used for food-contact applications?

A: No. While non-toxic post-cure, it is not certified for direct food or beverage contact.

Q6: What safety precautions are required during application?

A: Wear nitrile gloves and eye protection. Ensure adequate ventilation to avoid inhalation of vapors.
