The GM-6069 amino-modified organosiloxane oligomer from Wenjing Chemical improves compatibility and performance of composite materials.
GM-6069 is an amino‑modified organosiloxane oligomer designed to enhance the compatibility between polymers and inorganic fillers in composite materials. It significantly raises mechanical strength, thermal stability, electrical performance and water resistance, and can act as a coupling promoter in surface treatment, coatings and inks.
Technical specifications include an average polymerization degree of 6‑8, a pale‑yellow transparent liquid appearance, pH 9‑10 (5% solution), usable temperature range 10‑40 °C, flash point 95 °C, density 0.96 g/cm³, and water conductivity requirement <100 µS/cm. The product is supplied in 25 kg drums, stored sealed in a dry, ventilated area, with a shelf life of 18 months. This manual is written in Chinese.
