INDOPOL H-1900 is a polybutene oligomer that provides excellent properties for various applications. INDOPOL H-1900 has high molecular weight and narrow molecular weight distribution ideal for formulations requiring stability and durability. INDOPOL H-1900 also has very low acid number and low chlorine content. Due to its low viscosity and refractive index, INDOPOL H-1900 can be used to improve the flow, leveling and transparency of coatings. INDOPOL H-1900 is an ideal additive for enhancing the performance of protective and decorative coatings by improving their weather resistance, adhesion and flexibility. INDOPOL H-1900 is permanently non-drying, colourless and non-staining, tacky, emulsifiable, excellent electrical insulator, good lubricant / shear stable, non-corrosive, practically non-toxic, stable to light and air (i.e. oxidatively stable) under ambient conditions, low pour point, complete depolymerisation.
