Manufacturers of seals and injection-molded products often struggle with these challenges:

• Insufficient sealing adhesion, causing leaks of water or air after just a few uses.

• Severe mold sticking during demolding, resulting in burrs that require extra polishing.

• Long production cycles due to time- and energy-consuming secondary vulcanization.

• Concerns about materials not meeting industry standards or adapting to complex applications like appliances and pipelines.

The IOTA LSR 3040 series secondary-vulcanization-free high-adhesion liquid silicone rubber stands out as the "efficiency expert" in the sealing industry. It delivers high adhesion to prevent leaks, easy demolding to streamline processes, and excellent mechanical properties, making production smoother and products more durable.

The core feature of this silicone—"high adhesion"—is like the "soul" of a seal. Once cured, it bonds to substrates as tightly as Velcro, maintaining a secure, leak-proof seal even under prolonged vibration or compression. The 1:1 two-component mixing ratio is incredibly straightforward—like blending "one part adhesive A with one part adhesive B"—making it easy for even non-specialized workers to achieve accurate proportions. Its viscosity resembles smooth silicone ointment, offering excellent flowability during injection to precisely fill every fine detail of the mold without obstruction. Demolding is a standout advantage: cured products release effortlessly from the mold, much like lifting glass from a suction cup—no sticking, no need for extra deburring, saving an entire processing step. The curing speed is astonishing—45 seconds at 150°C (the time it takes to brew a cup of coffee) or 90 seconds at 130°C, with no secondary vulcanization required, drastically shortening production cycles.

In the realm of seals and injection-molded products, its performance is truly versatile:

• Appliance seals (e.g., refrigerator door gaskets, washing machine door seals) stay firmly in place thanks to high adhesion, ensuring airtight and watertight sealing for better insulation, moisture resistance, and extended appliance life.

• Pipeline seals offer high adhesion and superior mechanical properties, creating leak-proof, corrosion-resistant, and aging-resistant seals for water, gas, and other pipeline applications.

• Consumer silicone injection parts (e.g., keyboard silicone keys, earbud tips) feature smooth surfaces and comfortable textures, with high adhesion ensuring tight integration and responsive press-and-release performance.

• Medical device seals (e.g., infusion set connectors, ventilator components) comply with ROHS standards, provide leak-proof adhesion, withstand sterilization, and are non-irritating and safe.

• Automotive small-sized seals resist high temperatures and aging, adapt to in-vehicle temperature fluctuations, and maintain long-lasting sealing to prevent oil or water leaks.

Using it is remarkably hassle-free—just remember a few key details:

• Always mix A and B components from the same batch to avoid compromising adhesion and mechanical performance.

• Stir materials thoroughly before transfer to ensure optimal flow and uniformity for perfect molding.

• As a platinum-catalyzed product, avoid substances that could "poison" the catalyst. Small-scale testing before full production is recommended to prevent waste.

• Store in a cool, dry place below 23°C. Unopened, it has a shelf life of 12 months. Beyond this period, a simple performance test can confirm continued usability.

Whether for automated injection production lines or small-scale manual manufacturing, it adapts seamlessly, enabling fast, stable production while ensuring high adhesion and durability in every product.
