Key Features and Benefits

• Strong Bonding to Diverse Materials: Bonds metals, wood, ceramics, and plastics including ABS, PVC, and polycarbonate.

• Toughened for Durability: Provides excellent impact and vibration resistance for demanding applications.

• Fast Fixture Time: Achieves working strength within 20 minutes at room temperature (23°C / 74°F).

• Easy Application: Smooth, quick flow and easy dispensing with a simple 1:1 mix ratio.

• High Environmental Resistance: Outstanding performance in water, humidity, saltwater, and chemical exposure.

• Wide Temperature Range: Cures at temperatures as low as 5°C (41°F) and withstands operating temperatures down to -40°C (-40°F) and up to high-heat conditions during processing.

• Non-Flammable and Solvent-Free: Safe and user-friendly for industrial environments.

Typical Applications

• Bonding polycarbonate panels and plastic housings

• Assembling electronic appliances and housings

• Repairing PVC, ABS, and composite components

• Marine and industrial repairs needing fast, tough adhesive solutions

Technical Properties

Performance Highlights

Strength Development:

• Fixture strength achieved in as little as 6 minutes at 23°C (74°F).

• Working strength achieved in 20 minutes, with full strength after 24 hours.

• At lower temperatures like 5°C (41°F), curing slows but remains effective for cold-weather applications​.

Hot Strength:

• ET503 retains significant shear strength even at elevated temperatures during brief exposures (such as paint baking or soldering processes).

• Full bonded assemblies maintain performance across a wide temperature range from -40°C (-40°F) up to high-heat processing temperatures​.

Shear Strength (ISO4587):

• Mild Steel: 20–26 N/mm² (2900–3770 psi)

• Aluminium: 18–24 N/mm² (2610–3480 psi)

• Polycarbonate: 5–8 N/mm² (725–1160 psi)

• ABS: 5–8 N/mm² (725–1160 psi)

• PVC: 5–8 N/mm² (725–1160 psi)

(Note: Strength may vary depending on surface preparation and application conditions.)
