FAST traces its development back to 1992 and focuses on water-based polymer materials, application-oriented product systems and B2B technical communication.
Who We Are
FAST first. Manufacturing behind it.
FAST is the customer-facing brand. Manufacturing infrastructure, production equipment and testing documentation support that brand rather than replace it.
Founded
1992
Focus
Water-based polymer materials
Applications
Leather, synthetic leather, textiles, printing, coatings
International Direction
Expanding into Southeast Asia
How we work
Customers can start from a product family, an application or a performance target. FAST then continues the discussion around product fit, samples and technical documentation.
Build a Material BriefDevelopment
More than three decades of water-based material work.
The timeline is based on the company history currently approved for website use.
1992FAST / Fukenai founded.
1998First Dongguan manufacturing facility established.
2000Acrylic emulsion R&D and production began.
2005Polyurethane emulsion R&D and production began; Shanghai manufacturing operations established.
2019Shanghai manufacturing operations relocated to Hubei, establishing the Hubei production base.
TodayFAST continues to develop water-based material systems with manufacturing support and a Shanghai operating presence.
Manufacturing Capability
Production infrastructure supports the FAST brand.
FAST presents manufacturing capability as evidence of production support, while specific factory identities remain secondary to the FAST customer relationship.

FAST uses physical leather and coating samples to support technical and commercial discussion with customers.
Company exhibition and sample display.
Quality & Compliance
Evidence tied to tested samples.
FAST avoids broad compliance claims where the documents only support selected products. The website keeps certification language within the scope of the actual reports.

Technical Insights
Publish only reviewed technical content.
The original blueprint includes technical articles, industry insights and company news. These are intentionally not populated with invented content. This section is ready for reviewed articles when FAST provides them.
Launch recommendation: keep empty News / Insights categories hidden until at least 3–5 real articles are approved. This avoids making the site look unfinished.
