Pourable Electronic Encapsulation Silicone High Flow Platinum Cure Silicone Sealant

is a low‑viscosity platinum‑catalyzed addition‑type RTV‑2 Liquid silicone rubber independently developed by Shenzhen Hong Ye Jie Technology Co., Ltd. It consists of flowable Part A and Part B, mixed at 1:1 by weight. It cures at room temperature; heating can accelerate curing speed. Its good fluidity is suitable for thin‑wall complex‑shape casting, supporting both laboratory prototyping and automated mass production.

This series offers Shore A hardness ranging from 0‑30A. Ultra‑soft grade 0‑5A is suitable for soft‑tissue simulation and movie special‑effect prosthetics. Medium‑soft grade 10‑15A is designed for humanoid robot skin and prosthetic inner liners. Medium‑hard grade 20‑30A applies to frequently‑used medical teaching models and museum display wax figures.

With ultra‑low shrinkage rate, this silicone can precisely replicate fine skin pores and subtle surface textures. After full curing, it delivers good tear resistance and elastic recovery. Repeated stretching and bending will not cause cracking or permanent deformation. Compared with conventional condensation silicone, it effectively avoids oil bleeding, surface stickiness and premature yellowing, extending service life of bionic finished products.

The silicone is odor‑free and non‑irritating, safe for indirect human‑skin contact. Custom skin‑tone, translucent and transparent colors are available. Excellent fluidity enables pouring and brushing molding, ideal for complex‑structure bionic parts.

Shenzhen Hong Ye Jie Technology Co., Ltd also supplies Mold Silicone, Pad Printing Silicone, Electronic Potting Compound, thermal conductive silicone, liquid and solid silicone rubber. We support sample testing, formula adjustment and bulk order delivery. Global buyers are welcome to inquire for TDS and quotation.

Main Features

1. Realistic skin‑like hand‑feel, natural wrinkle recovery after deformation
2. 0‑30 Shore A wide hardness selection for diversified bionic projects
3. Low‑viscosity fluidity, good for complex‑shape pouring molding
4. High tear strength, anti‑aging, anti‑yellowing and low oil‑bleeding
5. Platinum addition system, skin‑friendly, no harmful volatile substances
6. Low shrinkage for high‑precision texture reproduction; customizable hardness, color and viscosity

Operating Instructions

Stir Part A and Part B separately before mixing to disperse settled fillers. Mix two components at 1:1 weight ratio for 2‑3 minutes, scrape container bottom and side walls. Vacuum degassing is strongly recommended to remove bubbles. Pot life is 30‑40 minutes at room temperature, full curing takes 4‑8 hours. Heating at 60‑80℃ can shorten curing time.

Notes

Platinum silicone will fail to cure when contacting sulfur, tin, lead or phosphorus substances. Molds and tools previously used for condensation silicone must be thoroughly cleaned. Avoid sharp‑object scratching and long‑term strong sunlight exposure. Small‑area skin test is required for skin‑contact finished goods.
