Causes 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......
2026-08-19Perhydropolysilazane should not be selected solely by comparing solids content and viscosity. Solids content affects the amount deposited per coating pass, while viscosity affects application behav......
2026-08-17Hardening, softening or cracking after high-temperature exposure does not necessarily mean that the silicone gum was selected incorrectly. The first step is to distinguish an oxygen-rich hot-air en......
2026-08-14High-temperature heat-transfer oil should not be selected solely according to the “maximum temperature resistance” stated in product literature. The correct sequence is to first confirm the ......
2026-08-13Possibly, but the appearance of the deposited film alone cannot confirm that the contamination comes from a silicone material. When enclosed equipment is heated, volatile substances from sil......
2026-08-13Both KH-550 and KH-560 can be considered as silane coupling agents for epoxy composites, but neither can be described as universally superior. KH-560 is an epoxy-functional silane and ......
