Applications

Compatible Substrates & Surfaces: Metal,

Plastics,

Polycarbonate (PC),

Polyethylene (PE)

Applications & Uses

General Instructions: Surfaces to be bonded must be clean, dry and free from grease, oil, wax, weak oxide films and other contaminants. Bring both components to room temperature prior to mixing. Measure out specified amounts of parts A and B and mix, without introducing bubbles, until homogenous. Meter-mix equipment equipped with an automatic purge is recommended for higher volume applications. Contact your H.B. Fuller representative for suggested application equipment to suit your specific needs. We recommend that containers be purged with nitrogen after they are opened to the air and not all the material is used.

Storage & Handling

Storage: Product should be stored in a cool dry place out of direct sunlight. The shelf life is from date of manufacture. Shelf life is based on the products being stored properly at temperatures between 16°C and 25°C. Exposure to temperatures above 25°C will reduce the shelf life. This product should not be frozen. Purge opened containers with dry nitrogen inert blanketing gas before resealing.
Shelf Life: 12 months
