Home/Quality Control

Strict Lab

Shenhong supports custom orders based on provided samples. You provide samples; Shenhong tests and customizes them, with a minimum order quantity of 10 tons per type.

I. Stringent Internal Control Indicators, Quality Exceeding Industry Standards

Our self-built standardized laboratory ensures that the industry color difference limit △E≤1.0, while our finished products maintain a stable △E≤0.8, exceeding general industry standards for color consistency.

II. Refined Testing System, Strictly Controlling Hidden Color Differences

We use 10x diluted samples of the original color + a high-end chromatograph for quantitative testing, magnifying subtle color defects and avoiding batch color difference risks missed by visual inspection.

III. Uniform Batch Color, Supporting Stable Production for Customers

Finished product color is visually indistinguishable, suitable for formulations in various fields such as bricks, coatings, and plastics, reducing color matching costs and finished product scrap losses.
