LINKER CL720 is an auxiliary agent which cross-links the acrylic and polyurethane binders used to finish the leathers.
When it is added to water and solvent fixing agents and to base coats, it enhances the finishes’ dry and wet rub-fastness properties and the finishing adhesions.
It is recommended its pre-dilute LINKER CL720 in MEK, or another suitable organic solvent, and water before the addition to the blends to be cross-linked. Recommended amounts are between 2 – 5% calculated on the resin weight. The blend’s pot-life is about 24 hours.
