01/2018Silica and Silica coated waxes

Silica is used as matting agent in printing inks, paint and coatings. During the production process Silica improves free flow behaviour and prevents from formation of coagulates.

Fumed Silica

DEUREX SILICA 200 (hydrophilic fumed Silica with specific surface [BET] of 200, 175 – 225 m²/g)

DEUREX SILICA 380 (hydrophilic fumed Silica with specific surface [BET] of 380, 340 – 420 m²/g)

DEUREX SILICA S 120 (hydrophobic fumed Silica with specific surface [BET] of 120, 90 – 150 m²/g)

  • Very porous surface of silica
  • Matting agent for extremely fine coatings and printing inks

 

Micro-sized Silica

DEUREX S 3012 M (S = Silica | 30 = 100 % Silica | 12 = 98 % < 12 µm | M = Micro-Sized)

DEUREX S 3017 M (S = Silica | 30 = 100 % Silica | 17 = 98 % < 17 µm | M = Micro-Sized)

  • Provide free flow
  • Strong matting effects
  • Various particle sizes for various applications from can and coil coatings to wood and industrial coatings, but also leather and film coatings

 

Silica coated waxes as matting agents

DEUREX S 3119 M (S = Silica | 31 = Silica double coated | 19 = 98 % < 19 µm | M = Micro-sized)

DEUREX S 3219 M (S = Silica | 32 = Silica fully coated | 19 = 98 % < 19 µm | M = Micro-sized)

DEUREX S 3319 M (S = Silica | 33 = Silica spot coated | 19 = 98 % < 19 µm | M = Micro-sized)

DEUREX S 3419 M (S = Silica | 34 = Silica eco coated | 19 = 98 % < 19 µm | M = Micro-sized)

  • Silica coated polymers for industrial and wood coatings as well as printing inks
  • Adapt matting effects with different stages of Silica coating
  • double coated Silica DEUREX S 3119 M as for maximum matting effects
  • eco coated Silica DEUREX S 3419 M for slight matting effects
