ROBOND L-330

Robond™ L-330 is designed for use as a two-component, VOC compliant, waterborne adhesive for laminating flexible substrates. The CR 9-101 coreactant must be used at the recommended mix ratio to achieve the desired adhesion and higher performance properties.

The principal uses for Robond L-330/CR 9-101 are to laminate a variety of substrates including treated polyolefins (minimum 38 dynes/cm²), aluminum foil, nylon, and treated polyesters. These laminations are intended for snack foods, dry food, condiment, and other medium performance packaging. Other application uses are possible, subject to performance trials and testing.
