Molecular weight: 637 (monomer), 975 (dimer)

Application: The dispersion of Synsorb-1130 in water borne systems may be eased by dilution with a water miscible solvent such as butylcarbitol.

Synsorb-1130 is recommended for both solvent and water based coatings such as:

automotive coatings

industrial coatings

trade sales coatings

Synsorb-1130 may be used in combination with a light stabilizer of the sterically hindered amine class (HALS) such as Synsorb-144, Synsorb-292 or Synsorb-123. These synergistic combinations impart superior coating protection against gloss reduction, cracking, blistering, delamination and color change. The light stabilizers may be added in two coat automotive finishes to the clear coat and to the base coat. However, according to our experience, the optimum protection is achieved by adding the light stabilizer to the topcoat.

The amount of Synsorb-1130 required for optimum performance should be determined in trials covering a concentration range.
