Anticrackings

This invention relates to substances that can be used to reduce VOC (Volatile Organic Compound) levels in water-based acrylic paints and coatings, particularly to achieve satisfactory paints or coatings. It has been found that cellulose-based particles, including cellulose-based fibers and nanofibril networks from cell wall materials, can be used to reduce VOCs while increasing rigidity and reducing cracking in dried acrylic paints and coatings. It is assumed that the organization of cellulose fibrils present in parenchymal cell walls is at least partially preserved in the cellulose-based particles of the invention, even if some pectin and hemicellulose are removed.

What is DTPD?

DTPD is a commonly used anticracking agent. Specifically, DTPD is described as follows:

• Properties: Brown-gray to black flakes or granules, soluble in benzene and acetone, insoluble in water.
• Application: An antioxidant particularly effective in neoprene, and can also be used in the rubber industry and many other rubber products. It provides excellent anti-ozone, abrasion, and cracking prevention performance. DTPD has good long-term performance, especially when used in combination with antioxidants A and D, such as 4020 or 4010NA at a 1:1 ratio. It significantly increases solubility in rubber and reduces blooming, with minimal effects on vulcanization and burning. It has the strongest resistance to toxic metals and the longest protective effect duration, making it especially suitable for truck tires, off-road tires, radial tires, and bias tires. It can completely alter the defects in tires compared to the use of red tire antioxidants like 4010NA and 4020.
• Packaging: Available in 25 kg bags.
• Storage: Store in a cool, dry, and well-ventilated place with the container tightly closed. Avoid exposing the packaged product to direct sunlight.
