long-term anti-yellowing aging-resistant robot skin silicone is a newly upgraded high-stability platinum-cured RTV-2 liquid bionic silicone developed by Shenzhen Hong Ye Jie Technology for dual working conditions of long-term static display and normal dynamic operation. Conventional bionic silicone on the market has weak aging resistance, prone to yellowing, darkening, mottled discoloration and surface stickiness after short-term use. The material will gradually harden and embrittle after aging, resulting in frequent skin replacement and high maintenance cost, unable to meet the long-term quality requirements of commercial robots and museum exhibits. This product adopts dual upgrading of molecular weathering structure and long-term anti-yellowing additives, fundamentally inhibiting oxidative discoloration and performance attenuation, achieving long-term color transparency and stable flexible texture for years.
This product adopts stable 1:1 weight ratio mixing, room temperature curing and heating accelerated curing, compatible with pouring and brushing processes, suitable for integrated molding of complex curved surface outer skin, facial skin and flexible palms. The hardness ranges from 5A to 30A. 5-12A soft grade is suitable for robot face, eyelid, lip and fingertip flexible skin with natural micro-expression deformation. 15-30A high-toughness grade is optimized for arm, torso and joint stressed skin, balancing aging resistance and mechanical durability for long-term continuous operation.
The core advantage is outstanding long-term anti-yellowing and aging resistance. After thousands of hours of light aging, air oxidation and alternating weather resistance tests, the cured silicone maintains uniform and transparent skin tone without yellowing, darkening or color difference. The reinforced molecular structure prevents elastic attenuation, surface powdering, hardening and stickiness after long-term use, keeping tear resistance, tensile strength and rebound performance stable, greatly extending the service life of bionic skin and reducing later maintenance cost.
With ultra-low curing shrinkage rate ≤0.08%, the material accurately reproduces human skin pores, fine lines and natural texture with high simulation degree. The upgraded color-fast formula ensures strong paint adhesion and stable color tone, resisting fading and mottling under long-term light and oxidation. It retains excellent dynamic simulation performance, with natural rebound and no residual wrinkles after repeated facial and joint deformation, balancing long-term weather stability and high-level bionic effect.
Adopting high-purity platinum eco-friendly curing system, the silicone is non-toxic, odorless and non-irritating with excellent biocompatibility, safe for long-term human contact and close display scenarios. It features moderate fluidity and excellent defoaming performance, reducing pinholes and improving finished product yield. It supports laboratory sampling, high-end customized production and automated mass production with stable batch consistency in color and performance.
Shenzhen Hong Ye Jie Technology has formed a complete differentiated bionic silicone system covering wear resistance, high tear resistance, low bleed dry touch, ultra-soft micro-expression and long-term anti-aging types, fully meeting the material selection needs of humanoid robots in different scenarios. We provide free sample testing, customized hardness and skin tone, professional technical guidance and stable bulk supply, helping global customers solve aging and discoloration problems of bionic products and achieve long-term stable commercial application.

Operating Instructions
Fully stir Part A and Part B before use to evenly disperse anti-aging additives and settled fillers for consistent weather resistance. Mix strictly at 1:1 weight ratio and stir thoroughly for 2-3 minutes with scraping bottom and walls. Vacuum defoaming is recommended to eliminate tiny bubbles and ensure uniform surface and stable performance. Room temperature pot life is 40-50 minutes, full curing for 5-9 hours. Heating curing at 60-80℃ accelerates production without damaging anti-yellowing and aging-resistant performance.
Notes
Platinum silicone will be poisoned and fail to cure when contacting sulfur, tin, lead and phosphorus contaminants. All molds and tools must be kept clean. Avoid long-term intense UV exposure and extreme violent pulling to prolong service life. Skin patch test is recommended for products with long-term human contact.
Packing & Storage
Part A and Part B packed separately in sealed drums: 5kg, 20kg, 200kg. Store in cool, dry, clean and sealed environment, away from high temperature, pollution and strong light. Shelf life: 12 months, transported as non-dangerous goods.
