CRISTOBALEX 3 is an ultrawhite, lower-density thermally modified and micronized cristobalite silica filler developed for coatings, adhesives, and sealants, maximizing L* light reflectivity across the visible and solar spectrum with reduced TiO2 while enhancing UV, abrasion, surface hardness, and chemical resistance. Median particle size is 13.9 microns with 97 TAPPI brightness, L* 98.2, 2.32 g/cc specific gravity, and 23.4 oil absorption.

CRISTOBALEX 4 is an ultrawhite, lower-density thermally modified and micronized cristobalite silica filler developed for coatings, adhesives, and sealants, maximizing L* light reflectivity across the visible and solar spectrum with reduced TiO2 while enhancing UV, abrasion, surface hardness, and chemical resistance. Median particle size is 10.4 microns with 97 TAPPI brightness, L* 98.2, 2.32 g/cc specific gravity, and 25 oil absorption.

CRISTOBALEX IG 35 is a coarse, granular ultrawhite thermally modified cristobalite silica filler (99.6% SiO2) for durable coatings and adhesives, maximizing L* light reflectivity across the visible and IR spectrum with reduced TiO2 while enhancing UV, abrasion, surface hardness, and chemical resistance. About 80% is retained between 50 and 70 mesh (297-210 microns), with L* 96.8, 2.32 density, 1.2 g/cm3 bulk density, and 6.5 Mohs hardness.

IMSIL 1240 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 9.2 microns with 4.8 m2/g surface area and 84.5 TAPPI brightness. As a coarser grade it offers texture, gloss control, and abrasion resistance in coatings and building products.

IMSIL A-10 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 2.4 microns with 6.1 m2/g surface area and 86 TAPPI brightness. As a finer, micronized grade it suits higher gloss paints, thin coatings, and inks.
