key features
Heat Resistance - KS-707 demonstrates exceptional thermal stability, maintaining its non-volatile content at approximately 50% after exposure to 150°C for 24 hours. The silicone base resists oxidation and decomposition, preventing film cracking or loss of release ability during prolonged high-temperature operations.
Low-Temperature Flowability - Formulated with methylic silicone fluid, KS-707 retains excellent flow characteristics even at -65°C. This ensures that an even release film can be formed in cold environments or low-temperature molding processes.
Viscosity Stability - KS-707 maintains stable viscosity across a wide temperature range. With a specific gravity of 0.99 at 25°C, it ensures predictable spreading and coating thickness both at ambient and elevated temperatures.
Chemical Stability - The silicone fluid in KS-707 is nearly inert and resists degradation from chemical exposure. It withstands alkali solutions up to 10% and acidic environments up to 30% without reaction. This stability ensures the agent does not deteriorate or leave corrosive residues on molds.
Non-Corrosive Performance - KS-707 is non-corrosive to metals such as aluminum, steel, and stainless steel. Regular testing shows negligible surface changes even after repeated applications. It causes no etching or oxidation, allowing for safe use on precision molds and tooling.
Low Surface Tension - KS-707 has a much lower surface tension than water or standard synthetic oils, enabling fast and uniform spreading. It easily forms an even film on detailed mold structures and micro-patterned surfaces, ensuring clean release and sharp surface definition of molded parts.
Rubber Industry - KS-707 is commonly used in the production of vulcanized rubber components, including seals, gaskets, and insulation parts. Its uniform release layer reduces sticking and tearing during demolding, achieving a release force reduction of up to 40% compared with untreated molds. This results in fewer defects, faster cycle times, and extended mold service intervals.
Resin Industry - In thermosetting resin molding, especially epoxy and phenolic systems, KS-707 ensures smooth release without residue buildup. The agent maintains coating integrity during long curing cycles, improving surface finish quality by approximately 25%. It helps prevent surface pitting and irregular gloss, contributing to higher-grade molded components suitable for precision assemblies.
Die Casting - KS-707 functions effectively in light-alloy die casting processes where molds reach temperatures up to 200°C. It prevents molten metal adhesion, maintains stable separation through repeated cycles, and minimizes soldering defects. This enhances dimensional accuracy and improves overall casting consistency, reducing maintenance downtime for cleaning and surface repair.
Surface Processing Industry - KS-707 is applied as an anti-stick or lubricating layer during coating and finishing operations. With a measured friction coefficient below 0.20, it enables smooth part separation from surfaces and fixtures. It also reduces contamination on work surfaces, supporting cleaner operations and improving throughput in surface treatment lines.
Synthetic Fiber Industry - In fiber extrusion and spinning, KS-707 acts as a processing lubricant, reducing friction between fibers and machine components. It enables stable fiber release even at drawing speeds exceeding 1,000 m/min, ensuring consistent filament diameter and minimizing breakage. The chemical inertness prevents deposit formation on spinnerets, extending machine uptime and maintaining product quality.
