Antibacterial Antimicrobial Bionic Skin Silicone

This antibacterial antimicrobial bionic skin silicone is platinum-cured RTV‑2 liquid silicone developed by Shenzhen Hong Ye Jie Technology targeting hygiene pain points of high-frequency public touching, medical rehabilitation interaction and children science popularization scenarios. Conventional bionic silicone is itself non-toxic, but the porous organic elastomer surface easily traps skin sweat, sebum and dander after repeated touching by large crowds. Under room-temperature enclosed conditions, bacteria breed quickly on the surface, biofilm forms, and eventually mold spots and odors appear. For hospitals and children science museums where strict hygiene is required, ordinary silicone surface cannot inhibit bacterial growth, creating cross-contact hygiene risks. Many high-frequency interactive robot projects have to disassemble the skin frequently for high-temperature disinfection, which accelerates silicone aging and cracking, raising operating costs.

This silicone compounds long-term stable antimicrobial agents into the molecular network. Antibacterial components bind firmly with the cross-linking structure, will not leach out with touching, cleaning or sweat soaking, and maintain broad-spectrum antibacterial effect for long service life. It follows standard 1:1 weight mixing ratio. It can cure at room temperature or with heating acceleration. Both pouring and brushing processes are supported for integrated molding of robot full-body skin, facial layers and hand contact areas. Hardness ranges from 5A‑24A. 5‑13A ultra-soft hygienic grade fits face, eyelid, lip and children-contact parts with soft touch and realistic skin texture. 14‑24A tough hygienic grade fits limbs and trunk for long-hour public touch operation.

Core advantages: broad-spectrum long-term antibacterial, mold resistance under high humidity, and tolerance to regular disinfection wiping. Different from ordinary silicone relying on frequent external disinfection, this material surface itself inhibits bacterial colonization and biofilm formation even without frequent cleaning, greatly reducing daily disinfection frequency. It maintains good bionic simulation capability with ultra-low curing shrinkage ≤0.08%, accurately reproducing human-skin pores and fine textures. The upgraded anti-mold formula prevents mold spots and odors in southern humid enclosed exhibition environments. It delivers balanced tear-resistance and anti-fatigue performance, resisting cracking and peeling under repeated joint flexion and micro-expression movement. The surface tolerates regular wiping with medical alcohol and mild disinfection wipes, without accelerating yellowing or hardening during routine hygiene maintenance.

The finished material meets medical contact safety standards, non-toxic and non-irritating, suitable for close touching by public visitors and children, especially for hospital and children science popularization devices. Moderate fluidity and good defoaming performance ensure high finished-product yield. Antibacterial performance is uniform across the whole product, without local weak antibacterial areas. Antibacterial indicators remain stable batch-to-batch, supporting prototype sampling and mass supply for large medical and science museum projects.

Shenzhen Hong Ye Jie Technology maintains a full differentiated bionic-silicone portfolio covering self-healing, hydrolysis-resistant, high-tear-strength, ultra-low-modulus, high-resilience, matte anti-fingerprint, zero-bleed clean-grade, low-odor low-VOC and this new antibacterial hygienic series. Customization for antibacterial performance adjustment and skin-tone matching is available. Free samples and full-set process guidance are provided to help medical and public interaction robot projects satisfy hygienic safety requirements.

Operating Instructions

Thoroughly stir Part A and Part B for more than 3 minutes before use to disperse antimicrobial modified components. Mix strictly at 1:1 weight ratio and fully stir scraping bottom and wall for 2‑3 minutes. Complete sufficient vacuum defoaming. Room-temperature pot-life 42‑52 minutes; full cure 6‑10 hours at room temperature. Heating at 60‑80℃ accelerates production without damaging core antibacterial performance.

Notes

Platinum-cured silicone must avoid contamination of sulfur, tin, lead, phosphorus to prevent curing failure and deterioration of antibacterial indicators. Keep tools and molds clean. For high-frequency touch scenarios, daily maintenance is recommended with mild medical disinfection wipes; avoid long-term soaking by strong corrosive cleaners. For children-contact and medical devices, complete full-set biological safety tests before commercial deployment.

Packing & Storage

Part A and Part B are separately sealed in drums: 5KG, 20KG, 200KG. Store in cool, dry and well-ventilated warehouse, keep away from high-temperature heat source. Shelf life: 12 months. Transported as non-hazardous goods.
