Analysis of the Selection of Water-based Paints for Wood Coatings

The challenge in formulating wood coatings is the diversity of existing water-based paints and their varied applications in the industry.

The wood coatings market typically requires significant testing of water-based paints to determine their suitability for the end-use wood coatings market.

▶Dry time;

▶Surface hardness (pendulum hardness);

▶Taber abrasion test to determine scratch resistance and wear properties (CS-10 wheel, 1000 revolutions/1000g weight);

▶Resistance to chemical media (ethanol/water, acetone, Formula 409, and water);

▶Resistance to black heel marks (BHMR);

▶Outdoor durability.

Researchers primarily consider the requirements of six different application areas: floors, cabinets, furniture, interior windows and doors, and outdoor woodwork, in an effort to help formulation designers choose the appropriate water-based paint emulsions:

▶Flooring

Researchers conducted the black heel mark resistance (BHMR) test, which is used to evaluate whether shoe prints can be removed. This is an important test for flooring. Coatings should also be wear-resistant (Taber abrasion test) and sufficiently hard (pendulum hardness), as a soft coating will absorb dust, leading to unwanted dirty marks.

▶Cabinetry

An important performance characteristic for this market is resistance to chemical media (stains). The main tests required by the Kitchen Cabinet Manufacturers Association (KCMA) for this market involve exposing the coating to media such as mustard, coffee, and vinegar. After a period of time, the media is removed to see if staining occurs. Also important for cabinets is excellent abrasion resistance (Taber abrasion test) and excellent stain resistance (pendulum hardness).

▶Furniture

Excellent stain resistance (pendulum hardness), abrasion resistance (Taber abrasion test), and water resistance (water droplets) are important properties for furniture coatings. In addition, excellent resistance to chemical media (stains) such as shoe polish, nail polish, soft drinks, and other media commonly seen in office environments should be identified as important criteria for evaluating office furniture coatings.

▶Interior Windows and Doors

In addition to excellent water and chemical resistance, good anti-blocking time is also an important consideration for coatings used on interior windows and doors.

▶Outdoor Woodwork

As expected, excellent weather resistance—including good light-fastness, no cracking, no chalking, no blistering, or yellowing—is very important for the outdoor woodwork coatings market.

There are a variety of water-based paint emulsions available for wood coatings, and finding the best technology requires not only a thorough understanding of the performance of water-based paint emulsions but also an understanding of the end uses of wood coatings, such as flooring, cabinets, furniture, interior windows and doors, and outdoor woodwork.
