Why We Use a Water-Based 2K PU Finish
Introduction
Golden Phoebe Wood is naturally beautiful.
Its flowing grain and shimmering golden fibers are what make every Namuva phone case unique.
But natural wood also deserves thoughtful protection.
A phone case is meant to be carried every day—in your hand, your pocket, your bag, and on countless surfaces.
That's why every Namuva phone case is finished with a premium water-based two-component polyurethane (2K PU) clear coat.
This finish helps preserve the beauty of the wood while providing the durability needed for everyday use.
What Is a Water-Based 2K PU Finish?
A water-based 2K PU finish is a professional-grade protective coating commonly used on high-quality wood furniture, cabinetry, flooring, and premium wood products.
"2K" means the finish consists of two components:
-
A base coating (Part A)
-
A hardener (Part B)
When mixed together, they chemically cure into a durable protective layer that is significantly stronger than ordinary single-component finishes.
Unlike simple varnishes that dry mainly through evaporation, a 2K PU finish forms a tougher and more stable coating through chemical cross-linking.
Designed for Everyday Protection
Your phone case experiences daily wear.
It slides into pockets.
Rests on tables.
Travels in bags.
Is handled countless times every day.
Our water-based 2K PU finish is chosen because it helps protect the wood against many common situations, including:
-
Everyday scratches
-
Light surface abrasion
-
Moisture from daily use
-
Fingerprints and skin oils
-
Normal household humidity
While no finish is completely indestructible, this protective layer greatly improves the durability of natural wood without hiding its character.

Protection Without Hiding the Wood
Some thick coatings make wood look like plastic.
That isn't our goal.
We carefully apply multiple thin coats of clear finish to protect the surface while allowing the natural beauty of Golden Phoebe Wood to remain visible.
The grain stays sharp.
The texture remains natural.
Most importantly, the signature golden shimmer continues to come alive as light moves across the surface.
This is one of the reasons Golden Phoebe Wood is so admired.

Why We Choose Water-Based Instead of Traditional Solvent Finishes
There are many types of wood finishes available.
We chose a modern water-based 2K PU system because it offers an excellent balance of performance and appearance.
Compared with many traditional solvent-based coatings, it offers:
-
Excellent clarity
-
Strong adhesion
-
Good scratch resistance
-
Reliable water resistance
-
Lower odor during production
-
A finish that allows the wood's natural color to shine
For us, the goal isn't simply to add a protective layer.
It's to protect the wood while respecting its natural beauty.
Part of Our Craftsmanship
Applying the finish is only one step in a much longer process.
Before the coating is applied, every wood veneer has already been carefully selected and hand sanded through seven progressive stages, from 320-grit to 1500-grit.
This meticulous preparation creates an exceptionally smooth surface and allows the golden shimmer to become more vivid before the protective finish is applied.

Easy to Maintain
Although the finish provides excellent everyday protection, a little care helps keep your phone case looking its best.
We recommend:
-
Wiping the surface with a soft microfiber cloth.
-
Avoiding prolonged soaking in water.
-
Keeping away from harsh chemical cleaners.
-
Storing it away from excessive heat when not in use.

Frequently Asked Questions
Is the finish waterproof?
Our water-based 2K PU finish provides excellent water resistance for normal daily use, such as accidental splashes or light rain. However, we do not recommend prolonged immersion in water.
Does the coating hide the natural wood grain?
No.
The finish is transparent and is designed to protect the wood while preserving the natural grain and the signature golden shimmer of Golden Phoebe Wood.
Will the finish scratch?
Like any premium finish, it can develop minor marks over time with heavy use.
However, the 2K PU coating offers significantly better scratch resistance than untreated wood and many standard clear finishes.
