BKSilicone – Sam Zhong

Sam Zhong is the founder of BKSilicone, with over 15 years of hands-on experience in the silicone industry. Since entering the field in 2009, he has focused on the application development and engineering practice of RTV-2 platinum-cure (addition-cure) silicone materials.

Unlike traditional professionals with a purely materials-oriented background, Sam’s career has been built entirely around real-world applications. He is both a front-line silicone mold maker and a silicone engineering practitioner deeply involved in formulation design and material optimization.

This dual perspective—spanning both the application side and the material side—allows him to accurately identify pain points across the entire process, from raw material to finished mold, and to deliver systematic, practical solutions.

Senior Mold Maker (Since 2014)

Since 2014, Sam has been directly engaged in silicone mold manufacturing, serving a wide range of craft and production fields, including chocolate, candles, soap, resin, plaster, and decorative casting.

Through long-term hands-on practice, he has participated in and refined every stage of the silicone mold-making process, including:

• Structural design

• Master model fabrication (3D printing / CNC)

• Silicone material selection

• Pouring and processing techniques

• Cure control

• Demolding and mold performance optimization

To date, he has led and completed the delivery of more than 1,000 custom silicone mold projects, developing deep expertise in mold stability, detail reproduction, and service life.

Silicone Materials Engineer (Since 2009)

As a long-term engineering practitioner specializing in RTV-2 platinum-cure silicone systems, Sam has developed a systematic understanding of silicone formulation structures, key additives, material performance limits, and application compatibility.

R&D Breakthrough

Dissatisfied with the instability commonly found in commercial raw materials, in 2022 Sam led the development of BKSilicone’s proprietary low-viscosity platinum silicone system.
This system has become one of BKSilicone’s signature materials, combining high flowability, strong tear resistance, and enhanced cure-inhibition resistance.

Technical Innovation

Sam successfully challenged industry conventions by reducing platinum silicone viscosity to below 2000 cps while maintaining self-deaeration and mechanical strength. He also overcame cure inhibition issues commonly associated with SLA 3D-printed resin masters.

His core technical philosophy is simple:
complex chemistry should serve a simple and reliable user experience.

Philosophy & Working Style

Sam believes that excellent silicone materials are not defined by data sheets alone, but by consistent performance in real production environments.

This application-first mindset ensures that BKSilicone’s materials remain closely aligned with real user needs, earning a strong reputation across craft production, creative design, modeling, and small-batch manufacturing.

At BKSilicone, Sam insists on acting as the first user of every product. All materials must undergo long-term testing in actual mold-making scenarios before being released to the market.

This principle forms the foundation of BKSilicone’s brand position:
“A material partner that truly understands applications.”

Personal Background

Sam Zhong’s Chinese name is 钟武.
He was born in 1984 in Qingyuan, Guangdong, China.

Driven by a strong connection to his hometown and confidence in local manufacturing, he chose to establish and operate BKSilicone in Qingyuan.

Passionate about knowledge sharing and reducing technical barriers in the industry, Sam welcomes engineers, designers, and mold makers from around the world to connect with him and explore new possibilities for silicone materials across emerging applications.
