Anti Sebum Robot Skin Silicone No Swelling Or Sticky Surface Under Long

Sebum resistant anti grease bionic skin silicone is anti-grease modified platinum-cured RTV-2 liquid bionic silicone developed by Shenzhen Hong Ye Jie Technology for commercial high-frequency interactive humanoid robot industry. A growing number of humanoid robots are deployed in exhibition halls shopping malls and science museums, receiving a large number of visitors touching their face and hand skin every day. Human hands secrete sebum grease. Hand cream skin care oil and various grease contaminants will continuously attach to bionic skin surface. Conventional bionic silicone has weak resistance to grease. Grease molecules slowly penetrate into silicone matrix. After long term accumulation, silicone swells and skin surface becomes sticky. Fine pores and lines of bionic skin get blurred and eroded. Even repeated wiping with wet wipes cannot remove internal residual grease and permanent marks remain. Tactile experience becomes greasy. Tear strength drops and skin gets damaged easily. Frequent skin replacement raises operation cost. Many robot prototypes perform well in short term lab test, but bionic skin quickly ages and fails after several months continuous exhibition operation due to sebum erosion, leading to machine downtime and poor display effect.

This sebum resistant anti grease bionic skin silicone adopts special molecular modification to form dense molecular chain structure and slow down grease penetration. It resists erosion from human sebum hand cream and skin care essential oil. Grease mostly stays on surface instead of penetrating deep into silicone body. After contamination, dust and grease can be removed simply with clean cloth and neutral detergent. Original skin texture and soft touch can be fully restored. It follows standard 1:1 weight mixing ratio and cures at room temperature, heating can accelerate curing. Both pouring and brushing coating processes are supported for integrated molding of face hand and fingertip high touch skin of humanoid robots. Hardness ranges from 2A to 15A. 2A‑6A ultra-soft grade fits facial and fingertip bionic skin with soft simulation and sebum protection. 7A‑15A grade is suitable for large-area skin on palm and arm, balancing grease resistance tear resistance and wear performance.

Core advantages: anti human sebum erosion, resistant to hand grease and skin care oil immersion, no swelling or sticky surface after long contact, low grease adsorption, skin texture recoverable after oil wiping. Most commercial bionic silicone only optimizes hand feel and tensile property without sebum resistance modification. It works fine with short time touch but suffers severe grease erosion in long term high frequency human interaction. This anti sebum dedicated bionic silicone specially solves skin swelling and sticky problems caused by sebum accumulation in exhibition scenarios. Surface will not swell or turn sticky after massive visitor continuous touch and skin texture stays sharp and clear. Ultra-low curing shrinkage precisely replicates fine human skin texture without texture expansion deformation under grease exposure.

The formula has passed large batches of accelerated aging test in sebum simulation liquid. Volume change rate remains low after long grease immersion. The attenuation of tear strength and rebound performance is minimal. Skin hardly gets soft blistered or peeled off. Platinum eco-friendly system is non-toxic and odorless, safe for direct human touch. The silicone has controllable fluidity and great defoaming performance. Large-area skin molding has few bubbles and uniform color. Batch anti-grease indicators are stable for small prototype sampling and mass skin production for exhibition humanoid robot projects.

Shenzhen Hong Ye Jie Technology maintains a full differentiated bionic silicone portfolio covering self-healing, hydrolysis-resistant, high-tear-strength, low-shrinkage precision molding, high-resilience anti-deformation, matte anti-fingerprint, zero-bleed clean-grade, low-odor low-VOC, antibacterial hygienic, weathering anti-aging, anti-static low dust accumulation, sensor-compatible flexible substrate, high elongation large stretch, wide temperature range stable and this new sebum resistant anti-grease series. Customization for hardness, skin tone and grease resistance indicators is available. Sebum accelerated aging test reports and sample evaluation can be provided to help commercial exhibition humanoid robot projects solve swelling and sticky skin issues caused by sebum grease erosion, extend service life of bionic skin and cut maintenance and skin replacement cost for exhibition sites.

Operating Instructions Stir Part A and Part B separately for more than 3 minutes before use. Mix strictly at 1:1 weight ratio and fully stir for 2‑3 minutes while scraping bottom and wall. Carry out sufficient vacuum defoaming after mixing to reduce bubble defects. Room temperature pot life is 40‑50 minutes; full curing takes 6‑10 hours at room temperature. Heat at 50‑70℃ to accelerate curing without damaging core anti-sebum and anti-grease performance. For commercial exhibition projects, make samples in advance and complete sebum accelerated aging reliability verification.

Notes Platinum cured silicone must avoid contamination of sulfur, tin, lead and phosphorus substances, which may cause curing failure and degrade grease resistance. Keep mixing containers and molds clean and dry. This material is designed for sebum and mild skin care oil resistance, not suitable for long time immersion of high concentration strong solvent or heavy grease. Keep finished products away from strong solvent contact to extend skin service life. Store in cool and ventilated warehouse away from high temperature heat source.

Packing & Storage Part A and Part B are separately sealed in drums: 5KG, 20KG, 200KG. Store in cool dry and ventilated warehouse away from high temperature heat source. Sealed shelf life is 12 months. Non hazardous goods, regular logistics available.
