JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.
Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). As a white pigment, it acts as a cost-effective alternative for TiO2. Some of the properties of Lithopone include high brightness and performance under UV exposure. Lithopone requires less wetting agent to achieve optimum wetting of its surface. It is commercially graded on the basis of amount of ZnS. Its grades include 28%, 30%, and 60% ZnS. As a comparatively inexpensive white pigment, Lithopone is presently used in various paint formulations, road marking paints, jointing compounds, and putties.
2. Versatility These anchors are suitable for various materials, including drywall, plaster, concrete, and brick. This versatility makes them a go-to option for various projects, from home improvement to professional construction.
1. Enhanced Stability One of the primary advantages of wedge bolts is the stability they provide to the formwork. During the concrete pouring process, the weight and pressure from the liquid concrete can cause formwork to shift or collapse if not adequately secured. Wedge bolts hold the forms in place, ensuring that they do not bow or fail under stress.
Their sharp points enable effortless insertion, while the thread design ensures a strong, stable hold that resists loosening over time Their sharp points enable effortless insertion, while the thread design ensures a strong, stable hold that resists loosening over timestainless steel hex head wood screws.1. Select the Right Anchor Based on the weight and type of object you want to secure, choose an appropriate nail expansion anchor.
One of the primary advantages of using neoprene washers is their ability to create a watertight seal. This characteristic is particularly beneficial in applications exposed to moisture, such as roofing, plumbing, and automotive systems. The neoprene washer prevents water ingress around the screw hole, which is essential in preventing rust and corrosion, thereby extending the lifespan of the joint and the materials involved. This property is invaluable in outdoor applications where exposure to rain and humidity can compromise structural integrity.
4. Cost-Effective Solution
1. Corrosion Resistance Brass is known for its excellent resistance to corrosion compared to other metals. This property makes brass self-drilling screws particularly suitable for outdoor use or in humid environments, where moisture can lead to rust and degradation over time.
