Emulsion Destabilization by Silicone Surfactants and IOTA 2204 Selection | IOTA Layering, floating oil, flocculation or a sudden viscosity change after adding a silicone surfactant should not......
2026-09-10Volatile Content, Cyclic Siloxane Residues and Batch Acceptance for Low-Volatility Silicone Oils | IOTA Viscosity and flash point alone cannot determine suitability for enclosed electronics, optic......
2026-09-09Selecting Silicone Waterproofing Materials for Concrete and Water-Vapor Permeability | IOTA First distinguish liquid-water absorption from water-vapor transmission. Silane and silane–siloxane ......
2026-09-08Evaluating DC 704 Replacement with IOTA 704: Fluid Mixing and Diffusion Pump Cleaning | IOTA Do not assume that DC 704 and IOTA 704 can be mixed merely because both are 704-type silicone diffusion......
2026-09-04Phenyl Material Selection and Yellowing Diagnosis for High-Refractive-Index LED Encapsulants | IOTA Phenyl-containing silicones can be evaluated when a higher refractive index is required, bu......
2026-09-04Causes and Formulation Adjustments for Thermal Grease Oil Bleeding, Pump-Out and Dry-Out | IOTA Oil bleeding, migration beyond the interface or central dry-out after high-temperature service should......
2026-09-04Causes of Low-Temperature Silicone Rubber Seal Failure and Selection of Methyl Phenyl Silicone Rubber | IOTA Hardening or leakage at low temperature cannot be solved solely by reducing room-temp......
2026-09-02How to Evaluate and Validate a High-Temperature Phenyl Silicone Oil Supplier | IOTA When purchasing high-temperature phenyl silicone oil, do not compare only viscosity, price or the highest temper......
2026-08-31When a high-temperature mold produces smoke and deposits, should you increase silicone oil viscosity or switch to methyl phenyl silicone oil? Smoke and deposits on a high-temperature mold do ......
2026-08-28Causes and Troubleshooting of Cracking in Polysilazane High-Temperature Coatings | IOTA Cracking in a high-temperature metal protective coating should not be attributed immediately to insuf......
2026-08-27An oil film inside the vacuum chamber, contaminated workpieces or deteriorating ultimate pressure does not necessarily mean that the wrong pump oil has been selected. First determine whether the eq......
2026-08-25Not knowing the exact product name does not prevent preliminary material selection. In industrial procurement, temperature, media, substrate, formulation, target performance and failure symptoms ar......
2026-08-24If the primary requirements are a thin, transparent coating with relatively high inorganic barrier performance, perhydropolysilazane (PHPS) can be evaluated first. If the film must withstand repeat......
2026-08-21Drying or coking of high-temperature bearing grease does not necessarily mean that the base oil lacks temperature resistance. Base-oil evaporation and oxidation, changes in thickener structure, rel......
2026-08-21Gradual hardening of a silicone rubber compound during storage is usually not caused by one raw material alone. Interactions between silanol groups on the silica surface and silicone-polymer chains......
