Silico® HF2060 Hydride-Terminated Silicone Copolymer
Silico® HF2060 is a high-purity, hydride-terminated methylhydrosiloxane-dimethylsiloxane copolymer (CAS No. 69013-23-6). This reactive silicone fluid contains Si-H functional groups that make it highly suitable as a crosslinking agent in platinum-catalyzed addition-cure silicone systems. It improves mechanical strength, flexibility, thermal resistance, and chemical stability in advanced silicone formulations.
