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.

Aplicação recomendada：

Coatings: solvent based coatings, water based coatings, industrial coatings, powder coatings, wood coatings
Tintas de impressão: tintas offset, tintas à base de solventes, tintas à base de água

Dados técnicos:

• Solidez à luz: O grau de resistência à luz é avaliado numa escala de 1 a 8 de lã azul, em que 1 = ‘medíocre’ e 8 = ‘excelente’.
• Estabilidade ao calor: Os valores de estabilidade ao calor indicados indicam a temperatura máxima a que o pigmento pode ser armazenado durante 10 minutos na sombra total e em reduções sem sofrer qualquer alteração significativa da cor.
• Absorção de óleo: A absorção de óleo é determinada com base na norma EN ISO 787-5 e indicada em g de óleo de linhaça por 100 g de pigmento.
• Sangramento em solventes: O sangramento em solventes é testado utilizando os graus de pó e a classificação visual é dada numa escala de 1 a 5 cinzentos
  em que 1 = ‘Hemorragia intensa’ e 5 = ‘Sem hemorragia”
