In continuation for the focus on R&D several main topics can be identified, such as the preference for Intumescent Coatings over Cementitious Coatings: Intumescent coatings are known for their fire-resistant properties, which makes them highly valuable in the construction industry. Intumescent coatings provide passive fire protection, and their popularity is expected to continue to grow as safety regulations and the need for long-lasting construction materials increase.
Here are some reasons for this preference:
Fire Resistance: Intumescent coatings are specifically designed for fire protection. When exposed to high temperatures, they expand and form a char layer, which insulates the underlying substrate. This expansion and char formation can delay the spread of fire and protect structural elements. In comparison, cementitious coatings might provide some fire resistance, but intumescent coatings are generally more effective in fire scenarios.
Thickness and Weight: This reduced thickness and weight make them more attractive in construction and retrofitting projects because they don’t add as much load to the structure. In some cases, the weight of cementitious coatings can be a concern, especially in applications where structural integrity is paramount.
Other benefits of intumescent coatings are:
- Aesthetic Considerations
- Ease of Application
- Flexibility and Compatibility
- Regulatory Compliance
Water-Borne Coatings as the “Green” Option: Water-borne coatings have gained market share because they are positioned as an environmentally friendly or “green” option. They have a lower volatile organic compound (VOC) content, which is better for the environment and human health. This trend reflects a broader shift in consumer and industry preferences toward more sustainable and eco-friendly products.
The continued investment in anti-corrosion smart coatings reflects the need for protective solutions, particularly for metals used in various applications, from fasteners to architectural, engineering, and construction (AEC) components. These coatings are designed to prevent corrosion and extend the lifespan of metal structures and components. The use of “smart” coatings suggests the incorporation of advanced technologies, such as sensors and monitoring systems, to provide real-time data on corrosion and coating performance. This aligns with the industry’s focus on longevity, maintenance, and efficiency.
The architectural coatings industry is indeed experiencing significant technological advancements, primarily driven by environmental concerns and the need for more efficient and sustainable solutions. Here are some notable developments:
Pigging Technology: Pigging technology is becoming a must-have for paint and coatings manufacturers. It involves using a pig (a device) to recover residual liquid products from pipelines, reducing waste and increasing yields. This technology is particularly valuable in the context of water- and solvent-based paints, pigments, and coatings. It not only helps minimize waste but also results in cost savings. By optimizing product recovery, pigging technology aligns with the industry’s focus on sustainability and efficiency.
Hydrophobic Coatings: Hydrophobic coatings are another area of significant innovation in the industry. These coatings are designed to repel water, making surfaces water-resistant and easier to clean. They find applications in various sectors, from the fenestration industry (windows and glass) to the fabrication of more durable steel and wood substrates. By preventing moisture-related issues and enhancing the durability of substrates, hydrophobic coatings are becoming increasingly important in construction and manufacturing.
These technological advances are driven by a combination of environmental awareness, efficiency goals, and the need for more durable and effective coatings. As the industry continues to evolve, we can expect to see even more innovations that address these concerns and improve the performance of architectural coatings.
In the architectural coatings industry, a significant portion of greenhouse gas emissions stems from indirect sources in the value chain, including the production of raw materials.
Recently BASF has launched a new series of renewable sourced acrylic binders. By incorporating Acronal® MB acrylic binders, which are produced with sustainably sourced bio-feedstocks, into architectural formulations, BASF helps its customers reduce the product carbon footprint in their paints.
One of the key advantages of this approach is that the resulting Acronal® MB binder is chemically equivalent to its fossil-based counterpart. This means that no reformulation is required in the production process. This is significant because it simplifies the transition to more sustainable materials without compromising product quality or performance.
Wanhua’s focus on developing new polyisocyanate grades with low volatile organic compounds (VOCs) and enhanced properties is a significant contribution to the coatings industry.
The development of polyisocyanate grades with 100% solid content and low viscosity is a crucial step toward reducing VOC levels in coatings. Some of these new polyisocyanate grades offer additional properties such as improved pot life and enhanced flexibility.
Thor as a leading manufacturer of isothiazolinone based confirmed a particular interest, during the ECS 2023, in the use of ACTICIDE® C 1, a new product utilizing Thor’s unique pure CIT technology now authorized for use in all member states of the EU, especially for raw materials and intermediates. Also the ACTICIDE® products from the MK series based on Thor’s AMME™ technology, using the proven active substance encapsulation technology to support the EU market with modern sustainable dry-film preservation solutions such as ACTICIDE® MKN 10.
The regulation of biocides, including acticides, in paints and coatings varies by region and is subject to different laws and standards, such as the EPA in the United states and the BRP in Europe.
In summary, customer preferences in the paint and coatings industry are increasingly influenced by factors like safety, sustainability, raw material prices and technology. These trends are likely to persist and evolve further.
