Test Methods

• Oil Absorption

  It is determined by the Spatula Rub-Out method using boiled Linseed oil on a glass plate.
  It is expressed as the amount of linseed oil per 100g of pigment.(gr/100gr)

• Specific Gravity

  It is determined using specific gravity cups and ex- pressed in units of gr/c㎥. Ethanol is used to remove air from the pigment particles.

• pH

  Pour 0.5g of the pigment into a triangular glass flask, add 10ml of methanol and 50ml of distilled water, cover it with a stopper, and shake well. After 30 minutes, the pH value of the filtrate is measured by the pH meter.

• Resistance to Solvent

  Put 0.2g of pigment in a folded filter paper, immerse in 20ml of solvent for 24 hours and then remove, and finally label the degree of solvent bleeding as 1~5.

• Resistance to Chemical

  Put 2g of pigment into a test tube, add 30ml of 2% HCI or 2% NaOH solution, and stir for 30 minutes. The degree of coloration of the filtrate is marked by grades 1~5.

• Heat Resistance

  0.4g of pigment is mixed with 200g of p.p (Homo Polypropylene) and tested at injection molding with increasing duration at constant temperature.

• Light Fastance

  The test specimens of full shade and tint shade are exposed to Xenon lamp using Weather-O-Meter, and the degree of color change is graded 1 ~ 8 using Blue Wool Scale.

• Assessment

  Resistance to Solvent & Chemical
  Scale 1 : Drastic Bleeding ~
  Scale 5 : No Bleeding
  

  Light Fastness
  Scale 1 : Poor ~
  Scale 8 : Excellent
