What is Chemlok205LH?
Chemlok205LH is a low Hazardous Air Pollutant (HAP) liquid primer developed for use under Chemlok covercoat adhesives. It enables strong adhesion between rubber compounds—both vulcanized and unvulcanized—and rigid substrates like metal. This blue liquid primer consists of a mixture of polymers, organic components, and mineral fillers dissolved or dispersed in a low-HAP solvent system. It is designed to deliver strong bonding performance while helping reduce environmental impact.
Composition and Structure
- Blue liquid formulation
- Dynamic viscosity: 10 to 550 cP (Zahn Cup #2, 10 to 100 seconds)
- Density: 886.7 to 958.6 kg/m³ (7.4 to 8.0 lb/gal)
- Solids content by weight: 21.5% to 26.5%

Key Properties
- Low-HAP primer for environmentally sensitive applications
- High compatibility with vulcanized and unvulcanized rubbers
- Provides consistent bonding performance
- Distinctive blue color for easy substrate identification
- Compatible with a variety of Chemlok covercoat systems
Applications of Chemlok205LH
- Serves as a primer under Chemlok covercoats like the Chemlok6125 and Chemlok6254 series
- Bonds rubber to metal and other rigid materials
- Suitable for use on phosphatized substrates for visual quality control
- Used in industrial and automotive rubber bonding processes
- Ideal for production environments requiring low-HAP compliance
Features & Benefits of Chemlok205LH
- Versatile: compatible with multiple Chemlok adhesive systems
- Easy to apply: can be brushed, dipped, sprayed, or roll-coated
- Durable: forms rubber-tearing bonds with strong environmental resistance
- Identifiable appearance: brilliant blue color simplifies visual inspection
- Environmentally recommended: low HAP content (only 6.45%) reduces harmful emissions
Comparison with Other Adhesive Tapes
- Unlike conventional tapes, Chemlok205LH offers molecular-level adhesion with rubber materials
- Remains effective in high-stress and high-temperature bonding environments
- Provides lasting performance even under environmental exposure
- Enables bonding during vulcanization, which tapes are not designed to support
