Product Description
Lord Chemlok 238(NW) Non-Polar Elastomer Bonding Covercoat Adhesive
Chemlok 238(NW) is a specialized covercoat adhesive manufactured by Lord, designed specifically for bonding non-polar elastomers. This black liquid adhesive features a non-chlorinated solvent system and offers excellent bonding performance for challenging rubber compounds.
Product Overview
This adhesive is engineered to bond non-polar rubber compounds based on butyl and EPDM, providing exceptional versatility for various bonding applications. It effectively handles uncured-to-cured systems and bonds between cured elastomers with similar compositions. Application methods include brush, dip, roll coat, or spray to accommodate diverse production requirements.

Key Features
Chemlok 238(NW) excels at bonding non-polar elastomers like Butyl and EPDM, which are typically difficult to adhere. Recommended dry film thickness is 10.2-25.4 microns (0.4-1.0 mil) for standard applications, while cured rubber bonding requires 25.4-38.1 microns (1.0-1.5 mil). Storage above 21°C (70°F) prevents gel formation; if gelling occurs, heating above 38°C (100°F) with high-speed agitation reverses the process.
Application Areas
Ideal for manufacturing rubber-metal composites requiring excellent resistance to weathering, hot air, and chemicals. Common applications include:
- Automotive door seals, window channels, and coolant hose connectors
- Architectural gaskets and sealing systems
- Weather-resistant damping components in industrial equipment
- Part repair and reconditioning of cured elastomers
