Formulators and engineers working on aerospace, satellite, optical, and optoelectronic assemblies can now evaluate MasterSil 981-LO, a two-component, addition-cured silicone system from Master Bond designed for bonding, sealing, coating, and encapsulating applications.

The system meets NASA low outgassing specifications, a primary qualification requirement for space-grade assemblies, and exhibits optical clarity in thin sections, according to Master Bond. It is 100% reactive, contains no solvents or diluents, and shows minimal dimensional change upon cure, which may be relevant for precision optical assemblies where substrate stress tolerance is critical.
