Pigment Red 507K

Product Description

Mica powder is a non-metallic mineral containing a variety of components, mainly SiO2, a content of Al2O3. Mica powder has good elasticity and toughness. Insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, strong adhesion and other characteristics, is an excellent additive. It is widely used in electrical appliances, welding electrodes, rubber, plastics, paper, paints, coatings, pigments, ceramics, cosmetics, new building materials and other industries.

Technical Performance

• Light fastness: The fastness to light be determined on injection molded plastic swatches of approximately 2 mm thickness. Test swatches exposed in QUV and the visual rating given on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
• Weather fastness: The fastness to weather is determined on injection molded plastic swatches of approximately 2 mm thickness. Test swatches exposed in Xenon Arc for 1000 hrs and the visual rating given on 1 to 5 Grey scale where 1 = ‘Poor’ and 5 = ‘Excellent’.
• Heat stability: The Heat stability indicated is the maximum temperature in ˚C at which a change of color (DE ≤ 3) occurs after a dwell time of 5 minutes in the barrel of an injection molding machine as per DIN EN 12877-1.
• Oil absorption: The oil absorption was determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
• Bleeding fastness: The fastness to bleeding in PVC-P is determined on a colored PVC film in contact with a white-pigmented PVC film in an oven at 140˚C for 2 hrs and the visual rating given on 1 to 5 Grey scale where 1 = ‘Poor’ and 5 = ‘Excellent’.
