What is Chemlok144?
Chemlok144 is a solvent-based, clear straw-yellow primer designed to promote adhesion to a wide range of polar substrates. It functions as both a primer and an adhesive, making it suitable for bonding metal, glass, ceramics, and engineered plastics. Chemlok144 also includes a special fluorescent additive that makes it visible under UV light, aiding in application verification without impacting performance.
Composition and Structure
- Solvent-based formulation
- Color: clear, straw yellow liquid

Key Properties
- Moisture-curing system
- Transparent under normal light, visible under UV
- Provides strong bonding to polar substrates
- One-coat application for efficiency
- Suitable for use in demanding environments
Applications of Chemlok144
- Steel, aluminum, brass, and e-coated metals
- Glass fabric, architectural and automotive glass
- Ceramic tile and vitrified clay pipe
- Concrete and various engineered plastics
- Reaction injection molding (RIM) of polyurethane on glass
Features & Benefits of Chemlok144
- Versatile: functions as both a primer and adhesive for a wide range of materials
- UV fluorescence: enables inspection for complete coverage and surface contamination detection
- Non-intrusive: fluorescent agent does not affect adhesion or shelf life
- Easy to apply: can be sprayed, dipped, or applied with a polyester felt applicator
- Single-coat convenience: reduces labor and material usage
Comparison with Other Adhesive Tapes
- Unlike surface tapes, Chemlok144 offers chemical bonding with improved durability
- Better suited for high-temperature or high-humidity applications
- Ideal for complex shapes or surfaces where tapes cannot conform effectively
- Allows for internal adhesion beneath coatings or finishes
