IMSIL A-8 is a microcrystalline silica filler produced from inert, naturally occurring alpha quartz (98.6% SiO2) with a grape-like morphology, easily wetted and dispersed in solvent or water-based systems and selected for tint retention, durability, and resistance to dirt and weathering. Median particle size is 1.6 microns with 7.3 m2/g surface area and 87 TAPPI brightness. It is the finest micronized grade, for high gloss paints, thin coatings, and inks requiring the tightest top size control.

MINBLOC HC 1400 is a high-clarity nepheline syenite antiblocking additive for packaging-grade flexible films, combining particle morphology, surface chemistry, and a 1.53 refractive index to deliver antiblocking performance with superior haze, gloss, and clarity without diminishing film mechanical properties. Chemically inert and non-absorptive, it does not interfere with slip agents, antioxidants, stabilizers, or colorants and suits masterbatch or direct addition; median particle size is 7.60 microns with 2.50 m2/g surface area.

MINBLOC HC 2000 is a high-clarity nepheline syenite antiblocking additive for packaging-grade flexible films, combining particle morphology, surface chemistry, and a 1.53 refractive index to deliver antiblocking performance with superior haze, gloss, and clarity without diminishing film mechanical properties. Chemically inert and non-absorptive, it does not interfere with slip agents, antioxidants, stabilizers, or colorants and suits masterbatch or direct addition; median particle size is 8.20 microns with 1.20 m2/g surface area.

MINBLOC HC 500 is a high-clarity nepheline syenite antiblocking additive for packaging-grade flexible films, combining particle morphology, surface chemistry, and a 1.53 refractive index to deliver antiblocking performance with superior haze, gloss, and clarity without diminishing film mechanical properties. Chemically inert and non-absorptive, it does not interfere with slip agents, antioxidants, stabilizers, or colorants and suits masterbatch or direct addition; median particle size is 4.30 microns with 3.30 m2/g surface area.

MINEX 10 is a micronized nepheline syenite functional filler and extender for paints, coatings, adhesives, sealants, and inks, easily dispersed in all conventional vehicle systems and giving brightness, tint retention, weatherability, and stain resistance with minimal resin demand. Median particle size is 2.4 microns with 90.5 TAPPI brightness, 4.9 m2/g surface area, and 31 oil absorption, an ultrafine grade preferred for higher gloss, powder, and clear paint systems.
