IOTA LSR 3221 series offers a breakthrough in leather coating technology, providing an optimal balance of strength, flexibility, and ease of use. This transparent liquid silicone rubber ensures outstanding mold release, high tear resistance (10–30 KN/m), and excellent elongation, making it perfect for demanding applications in fashion, accessories, and protective gear.
Suitable for bags, shoes, infant products, and general leather items, IOTA LSR 3221 allows manufacturers to adjust coating layers based on desired thickness and performance. Its low viscosity enables smooth spreading, while the cured material exhibits consistent Shore A hardness between 10 and 50. An optional surface finish can further enhance tactile feel, elevating the end product's appeal.
Processing is straightforward: mix components at a 1:1 ratio, degas if needed, and cure at 120–140°C for 3–5 minutes. The mixed compound remains usable for 48 hours at room temperature. Uncurred material can be cleaned with hydrocarbon solvents, ensuring easy maintenance during production.
Available in 20 kg pails or 200 kg drums, IOTA LSR 3221 guarantees stable performance for up to 12 months when stored correctly. Tailored modifications in color, hardness, and thermal properties are also supported. Choose IOTA LSR 3221 to achieve durable, soft-touch leather products that stand out in today’s competitive market.
