Melamine Wood Coating AH1103 – Double the Adhesion Power

I/ Melamine Wood – Stylish but Hard to Paint

Melamine wood coating has recently become a heated topic in the wood market.  In modern interior design, melamine is considered one of the most popular materials thanks to its high aesthetic appeal, durability, and affordability. However, applying paint to melamine surfaces remains a significant challenge for carpenters and furniture manufacturers due to its unique structure.

Structure of Melamine Wood

Melamine panels are typically composed of three main layers: (1) a core board made from wood particles, (2) a decorative paper layer, and (3) a melamine resin layer. The outer layer, made from melamine-formaldehyde resin, serves as a protective coating. This layer gives melamine its smooth and glossy surface, along with water resistance and ease of cleaning. However, it is also prone to scratches and presents difficulties when attempting to apply additional coatings or paint.

There are generally two types of melamine boards: coated and uncoated. The difference lies in the melamine application process. Laminated melamine boards are made by pressing decorative paper soaked in melamine resin onto the surface, then heat-pressing it to form a hardened film. This type is more durable than the non-laminated version. Nevertheless, both types—especially the laminated ones—significantly reduce the adhesion of paint and coating materials.

II/ Common Issues When Coating on Melamine Wood

1/ Blotchy, Uneven Paint Coverage

Due to the slick and glossy surface of melamine, one of the most common issues is that the paint doesn’t adhere well. This often results in the paint running off or spreading unevenly, creating blotchy and inconsistent coverage.

2/ Peeling After a Few Days or Post-Curing

Another frequent problem is peeling. This typically occurs a few days after painting or immediately after heat-curing the product. Since melamine surfaces have low paint adhesion, the paint layer can lose its grip and start peeling off over time.

3/ Time-Consuming Sanding with Poor Results

Melamine is a multi-layered material and often thicker and tougher than regular wood panels. It takes more effort and time to sand properly. Uneven sanding can easily expose the MDF core underneath, ruining the aesthetics. Worse, over-sanding can damage the melamine layer itself.

4/ Poor Durability and Color Performance

Because of melamine’s poor adhesion properties, paint coatings can’t perform at their best. In projects that demand fast turnaround and consistent quality, poor adhesion to melamine wood can lead to product defects, project delays, reputation damage, and increased repair costs.

III/ Biochem’s Optimal Solution: Biomass Melamine Wood Coating AH1103 – Adhesion Promoting Sealer

Recognizing the urgent needs of the furniture industry, Biochem has developed a specialized water-based 2-component polyurethane sealer (2K PU) – code AH1103 – designed specifically for low-adhesion surfaces like melamine.

What is AH1103?

AH1103 is a 2K water-based PU adhesion-promoting primer. When combined with a specialized hardener, it forms a strong chemical bond with melamine surfaces. This ensures superior adhesion and long-lasting performance, even on the most challenging substrates.
