PERMUTHANE® XR-28-404 is a water-dispersible aliphatic polyisocyanate used to crosslink aqueous polymeric dispersions, improving resistance to moisture, heat, and solvents. Careful handling and mixing with water are essential to avoid pressure buildup due to carbon dioxide formation.

PERMUTEX XR-5508 is a solvent-free, waterborne, 40% active Polycarbodiimide crosslinker. It is an odourless liquid.

RelcaLink® 71 is a water based polycarbodiimide crosslinker. Key benefits • Crosslinks carboxyl functional polymers at room temperature • VOC and label free • No yellowing • Suitable for water based systems • Enhances water, chemical, stain and abrasion resistances Recommended applications • Depending on the binder and additives, pot lives of up to several weeks can be achieved • To achieve longer pot lives, it is recommended to formulate at pH > 8 • Recommended dosages 4 to 8% on binder formulation

RelcaLink® 72 is a 100% solids polycarbodiimide crosslinker to enhances water, chemical, stain and abrasion resistance.
