10 Years. One Focus.

We’ve dedicated a decade to perfecting joint sealant technology. Today, Zonenico products are trusted by contractors in Singapore’s toughest climate.

Who We Are

Changzhou Zonenico Building Materials Technology Co., Ltd. is a 100% factory-direct manufacturer of epoxy and polyurea two-component joint sealants. Founded in 2016 and headquartered in Changzhou, China, we operate our own R&D lab and production lines—no middlemen, no trading company overhead.

For 10 years, we have served the Chinese domestic market under the brand 众力高 (Zonenico), earning recognition from Alibaba as an industry leader and accumulating thousands of authentic user reviews on Xiaohongshu (RED). Our products have been used in hundreds of thousands of residential and commercial projects across China.

In 2024, responding to growing international demand, we launched our export division with Singapore as the first target market.

Our Strengths

Real Factory, Real R&D

Unlike many "manufacturers" who are actually traders, we own and operate our production facility. Our in-house R&D team continuously improves formulations for better color stability, adhesion, and ease of application. Every batch is tested before shipping.

Award-Winning Quality

Zonenico has been recognized with multiple Alibaba industry awards for product quality and customer satisfaction. On Xiaohongshu, thousands of real users have shared their renovation results using Zonenico joint sealants—organic proof of our product’s performance in real homes.

Climate-Proven in Singapore

Since 2024, a Singapore-based contractor team has been purchasing Zonenico products monthly. For 2 consecutive years, through Singapore’s high heat and humidity, our epoxy and polyurea formulas have maintained zero yellowing and zero de-bonding—validating our quality in one of the world’s most demanding tropical climates.

Color Customization Service

With hundreds of standard colors and custom color matching capability, we help contractors win projects that require precise tile-to-grout color coordination. Send us a tile sample, and we’ll match it exactly.
