Chemlok 489/456 Adhesive
Two-component adhesive for injection molding
Chemlok 489/456 is a two-component adhesive system designed for bonding PVC to prepared metals, glass, and plastics during injection molding. Its low viscosity allows for easy application using various methods, and it only requires a single coat for most applications. The adhesive offers durable performance, maintaining its bond strength even after exposure to heat and water. The Chemlok 456 curative includes a fluorescent tracer, enabling easy confirmation of proper application using UV light.

Features and Benefits
- Easy to Apply - low viscosity allows for easy application by spray, brush, wick or dip methods.
- Convenient - requires only a single coat for most applications. No preheating of primed substrates is necessary prior to injection molding.
- Durable - provides PVC cohesive tearing performance both at room temperature and after exposure to heat and water environments.
- UV Fluorescence - Chemlok 456 curative contains a fluorescent tracer that will fluoresce or glow when exposed to a low or medium intensity UV light; permits detection of curative in the resin; provides confirmation of the mixed adhesive on the bond surface.
Typical Applications
- Injection molding of PVC to metal
- Injection molding of PVC to glass
- Injection molding of PVC to plastic
Shelf Life/Storage
Shelf life of each component is one year from date of manufacture when stored by the recipient at 21-27 C (70-80 F) in original, unopened container. Do not store in sunlight. Chemlok 489 resin and Chemlok 456 curative are moisture sensitive, individually and when mixed together. Minimize exposure to moisture.
