After painting, MDF still needs to inspect the material itself
MDF Mould appears after painting. The problem may involve the combination of substrate, glue and surface coating. Our related material evaluation analyzes MDF along with the glue used, and separately considers anti-mould treatments in water-based coatings and nitrocellulose paints.
We sorted out the construction sequence of substrate, bottom layer and surface layer, listed the water-based and solvent-based processes respectively, and designed the addition and control experiments of each layer.

Prepare samples for water-based system and solvent-based system separately
Water-based and solvent-based coatings are equipped with corresponding anti-mould raw materials, and the dispersion, construction, film formation and anti-mould status are compared through actual plate coating samples.
Prepare samples to record glue, coating, adding process and drying conditions; single-layer processing and combined processing are grouped independently to analyze the impact of each layer of processing.
Cultivate observation and look at the board surface and the surrounding area at the same time
The figure records the culture status of different MDF process samples. Observe the covering plate surface, cut edge and surrounding culture medium respectively, and analyze according to the formula and treatment method of each group.
These photos correspond to material culture observations of different process groups. We combined grouping conditions with plate surface, cut edge, and media records to analyze each processing path.


In combination processing, first clarify which layer of problems to solve.
The water-based layer and the solvent-based layer were respectively set up as untreated, single-layer treated and combined treated samples to analyze the protection position and combination process.
We make addition arrangements based on the board, glue, paint and processing conditions, and provide corresponding process support when materials or formulas change.
Coordination of coating process and trial production
We use production methods to make coating samples to compare appearance, construction, drying and mould-proof performance. The work shall be equipped with protection and ventilation according to the corresponding product information.
In the packaging process, boards and auxiliary materials are inspected simultaneously, moisture linings, cartons and wooden packaging materials are classified and processed, and drying, painting and storage and transportation protection are connected.
Frequently asked questions
Can all MDF mould be cured by just adding a mould inhibitor to the topcoat?
We established groups according to the structure of substrate, glue, bottom layer and surface layer, and analyzed the role of anti-mould components through single layer and combined treatment samples.
Should mould growth on the culture medium and mould growth on the board be recorded separately?
Observe and record the board surface, cut edge and peripheral culture medium at the same time, and then analyze the anti-mould performance of the material based on the grouping conditions.
Can water-based paint and nitrocellulose paint use the same addition scheme?
The water-based and solvent-based coatings are matched with anti-mould additions respectively. In the combined treatment, the adding positions and processes of each layer are recorded, and actual painted panels are used for comparison.
