Manufacturing & R&D

Korean chemistry. Thirty years of materials science.

Manufacturing

Two processes. One studio.

Wet Process

Plant 1

The wet process produces our core PU synthetic leather through a multi-stage bath system. Base PU resin and DMF solvent are precisely formulated, filtered, and degassed before coating. The coagulation bath initiates controlled phase separation — creating the cellular structure that defines the material's feel. Multi-stage washing removes residual solvents. Tenter dryers set final dimensions.

Dry Process

Plant 2

The dry process applies PU in successive skin layers onto a release paper, enabling precise control of surface texture and handle. One and two skin layer configurations are available. The substrate lamination and maturation stages ensure complete solvent removal and bond integrity.

R&D Since 2011

We develop. We test. We iterate until it passes.

Most synthetic leather suppliers match from inventory. We begin with your requirement. Our R&D center — established 2011 — holds a patent on high-density textile manufacturing processes acquired in 2008. Every new specification goes through the same rigorous cycle before it ships. This same process applies to entirely new material development. If no existing product meets your requirement, our team formulates from first principles — developing a new PU construction specifically for your application.

01

Client briefs specification

Application, performance targets, color reference, and thickness range.

02

R&D formulates recipe

PU resin composition, coating parameters, and process conditions are configured.

03

Test batch produced

Small-run production batch on the live production line.

04

Internal ASTM testing

Full test suite run against the client specification and our internal pass criteria.

05

Sample sent to client

Physical sample dispatched within 3 business days of internal pass.

06

Iteration

If the client requires adjustments, we reformulate and re-test. As many rounds as needed.

07

Specification locked

Final recipe, process parameters, and test results documented.

08

Production begins

Full-scale production against the locked specification.
