Eco-Friendly Product | Keytec's Lead Chrome-Free Colorants

Eco-Friendly Product | Keytec's Lead Chrome-Free Colorants

With the spread of environmental awareness and the strengthening of national environmental protection policies, water-based industrial coatings, as an important category of environmentally friendly coatings, have seen rapid market development in recent years. In response to the demand for environmentally friendly and green products, Keytec has launched a series of water-based eco-friendly colorants for industrial paint.

 

As is known to all , one of the common sources of heavy metals in industrial paints is lead-chrome pigments. The use of lead-chrome pigments in coatings poses significant safety risks. To address the potential issues associated with lead-chrome pigments, Keytec has introduced an eco-friendly alternative to lead-chrome color pastes such as Y263-S. The followings are some test results based on this product:

 

1. Tinting Strength Evaluation

Taking the commonly used medium chrome yellow as an example, we added water-based medium chrome yellow and Keytec’s lead-free medium yellow Y263-S to a 5% varnish, stirred, dispersed, and compared their coloring properties after blade application. The experimental results showed that in the varnish, Keytec’s lead-free medium yellow Y263-S had comparable covering strength to medium chrome yellow, with vibrant colors.

 

2. Aging Resistance Test

Placed the prepared experimental sample of lead-free medium yellow Y263-S (5%) in a xenon lamp test chamber for accelerated artificial aging for 250 hours. The experimental data revealed that the color difference value of Y263-S paint after aging was only 1.63, with almost no color change. Keytec’s lead-free medium yellow Y263-S demonstrates excellent weather resistance.

 

3. Safety and Environmental Protection

In terms of safety and environmental protection, Keytec’s lead-free chrome colorants  passed halogen testing and 15 heavy metal tests, making it a highly cost-effective, eco-friendly alternative product. In the light anti-corrosion field of water-based industrial coatings, lead-chrome pigments are often seen. Keytec’s Y263-S and other lead-free chrome eco-friendly products can perfectly replace traditional options in terms of hue, covering power, and weather resistance.

 

With increasing environmental awareness and the gradual improvement of environmental regulations, the demand for eco-friendly coatings will continue to rise. As an important component of environmentally friendly coatings, water-based color paste will play a more significant role in the future market. Keytec will continue to focus on customers, operate with craftsmanship, and contribute to the greening and environmental protection of water-based industrial coatings.
