FAST CURE IN EXTREME WEATHER
- Cardolite phenalkamines and phenalkamides exhibit fast cure even at low temperatures, enable non- critical mix ratios, and show nice film appearance due to good compatibility with epoxy resins.
- However, due to the long aliphatic side chain of cardanol, CNSL curing agents also have extended pot life and good flexibility.
- The fast and low temperature cure combined with the good pot life properties of CNSL hardeners allow for wider adhesive application window and increased productivity.
- Faster cure means quicker return to service for two component field applied adhesives.
- In forced cure industrial applications, phenalkamines and phenalkamides can help save energy by lowering oven cure temperatures, or improving process efficiency via increased production line speeds.
- Finally, by reaching a high level of crosslinking very quickly and not having a narrow mix ratio, failure risks are lowered and problems avoided when environmental conditions change after application.
BONDING UNDER WATER
- Cardolite curing agents are very hydrophobic due to the long aliphatic chain of the cardanol which provides excellent water resistance compared to other amine curing agents commonly used in the adhesive industry.
- Phenalkamines and phenalkamides absorb much less water than competitive technologies which becomes more noticeable at higher temperatures exposure.
- The hydrophobicity of CNSL products coupled with their fast cure allows adhesives to quickly develop strong bonds to wet metal, damp concrete, and under water structures.

Storage & Handling
- Shelf Life
- 6 months
- Storage Condition
Cardolite products may absorb moisture and carbon dioxide when left in open containers, which could result in increased viscosity, discoloration, reduction of reactivity, and/or crystallization of the products. These products should be kept tightly sealed in their original containers when not in use, and stored in a cool, dry place.
