Product Description – PB15:4

HP BLUE 4558 (PIGMENT BLUE 15:4) shows largely the same coloristic and fastness properties as P.B.15:3 types, but often exhibit much better rheology. As with stabilized Copper Phthalocyanine Blue types, stabilization through surface treatment has proven to decrease the solvent fastness of Copper Phthalocyanine Blue, sometimes considerably so, making the pigment more sensitive to aromatics, alcohols, ethylene glycol, and ketones. It also gained importance in gravure printing inks, particularly in toluene based publication gravure printing inks and in various types of flexographic printing inks. They now dominate in these areas. It is optimized for use in specific media, such as publication gravure printing inks. In these media the pigment exhibits high tinctorial strength and good flow.

Applicazione consigliata：

Coatings: solvent based coatings, water based coatings, industrial coatings, powder coatings, wood coatings
Inchiostri da stampa: inchiostri offset, inchiostri a base solvente, inchiostri a base acqua

Dati tecnici:

• Solidità alla luce: La solidità alla luce è valutata su una scala da 1 a 8 Blue Wool, dove 1 = ‘Scarso’ e 8 = ‘Eccellente’.
• Stabilità al calore: i valori di stabilità al calore indicati indicano la temperatura massima alla quale il pigmento può essere mantenuto per 10 minuti in ombra e in riduzione senza subire variazioni significative della tonalità.
• Assorbimento di olio: L'assorbimento di olio è determinato sulla base della norma EN ISO 787-5 e indicato in g di olio di lino per 100 g di pigmento.
• Sanguinamento con solventi: Il sanguinamento nei solventi viene testato utilizzando i gradi di polvere e la valutazione visiva viene data su una scala da 1 a 5 grigi.
  dove 1 = ‘Forte sanguinamento’ e 5 = ‘Nessun sanguinamento”.”
