Can the amino silicone oil produced by Qiangli Chemical be applied to soft masterbatch? It is applicable, but it is necessary to select the correct model, control the amine value and processing temperature, and emulsify first before pelletizing.

High-purity dimethyl silicone oil (PDMS) has no obvious fluorescence reaction and barely glows under 365nm ultraviolet light.

Ordinary low-viscosity dimethyl silicone oil (e.g., 100–500 cSt) cannot be used directly; only high-viscosity, high-purity, thermally stable grade dimethyl silicone oil (typically 3000–10000 cSt, and 20000–30000 cSt for some vehicle models) must be used.

PDMS base adhesive mainly uses vinyl-terminated silicone oil for addition-cured systems, or hydroxyl silicone oil (107 silicone rubber) for condensation-cured systems, together with crosslinking agents, catalysts and fillers.

Simply put, it is polydimethylsiloxane with alkoxy groups (-OCH₃ / -OC₂H₅) at both ends of the molecular chain, belonging to reactive silicone oil, also often called alkoxy-terminated polysiloxane.

For thermal conductive pads, vinyl silicone oil for addition-curing systems (crosslinked with hydrogen-containing silicone oil) is mainly used, together with high-viscosity dimethyl silicone oil to adjust hardness and prevent oil bleeding. The viscosity must be matched to the processing method, hardness, thermal filler loading, temperature resistance and anti-bleeding performance.

Amino silicone oil can be compounded with resins and can also act as a curing agent (crosslinking agent), especially in epoxy resin systems; it is also applicable to some silicone resin systems.

Silicone Oil Types for Aluminum Die-Casting Mold Release Agents Long-chain alkylaryl-modified silicone oil is the most commonly used, followed by phenyl silicone oil and general-purpose methyl silicone oil. The selection is based on temperature resistance, carbon deposition, lubrication, and post-coating requirements.

For cleaning spinning heads, low‑viscosity, medium‑low amine value, easily emulsifiable, easily washable, and high‑temperature resistant amino silicone oils are preferred. Qiangli Chemical offers several suitable amino silicone oils, which should be selected based on your cleaning process and spinning system.

For car paint glazing, low to medium amine value amino silicone oil (0.2–0.6 mmol/g) is preferred. High amine value (>1.0 mmol/g) is not suitable for long-term outdoor paint surfaces.
