Antistatic additives for solvents

We deal with static electricity every day. On the bigger scale though, for example for the industrial plastics, static electricity becomes more problematic, as the resulting charge on surface can lead to attraction of the dust and small objects to the surfaces, difficulties in further processing of the object and sometimes discharge with generation of sparks — an obvious fire hazard in some conditions. Antistatic agents are used to combat this problem.

They are typically distributed either in the bulk of the material or on the surface, and their role is to make surface more conductive, which helps to avoid surface charge build-up. Ionic liquids have a set of properties that make them very useful as antistatic agents, including:.

ILs have been tested as antistatic additives to variety of plastics, showing reduction of surface resistance by at least the factor of We would be happy to discuss ionic liquids that would be useful for your specific application, so feel free to contact usshould you have any questions.

Physical property data.This diagram provides average trends compared with other additives based on OCSiAl data. Product performance may vary depending on product type and formulation. Graphene nanotubes also known as single wall carbon nanotubes demonstrate a number of advantages in comparison with standard anti-static additives.

In contrast to carbon black, graphene nanotubes enable conductivity in polyurethane along with preserving hardness and tensile strength. The advantage of nanotubes over ammonium salts is in their permanent electrical conductivity in thermoset compounds. It consists of black flakes with a paste-like texture and can be diluted into resin using a high-speed mixer, a bead mill or a three-roll mill depending on product type. Nanotube-based suspensions are liquid and can be easily diluted by strirrer.

OCSiAl has developed various nanotube solutions for hot cast, solvent-free, solvent-based, water-based or latex polyurethane systems. Concentrates and suspensions can be applied to rigid, flexible, foam or any other type of PU. Polyurethane products enhanced with graphene nanotubes meet the growing demand in agriculture, electronics manufacturing, mining, textile and packaging, oil and gas.

OCSiAl —If static charge is generated more quickly than it can be taken away, there is potential for static discharge. If this charge discharges as a spark it can lead to a number of problems in terms of process manufacture from pitting of the vessel to explosion.

The electrostatic hazards of liquids are not always well understood. An electrostatic charge can build up within a liquid, particularly those with low conductivity such as hydrocarbons.

Even with the pipe or vessel being earthed, a charge can remain within the liquid for a period of time 1, 2. Electrostatic charge is generated when two dissimilar surfaces — such as the liquid and the walls of the vessel or piping- come into contact. The electrical properties of the solvents play a major role in determining both charge generation and relaxation.

Static electric charge on a liquid in a grounded conductive container will dissipate at a rate that depends on the conductivity of the liquid. The conductivity of a liquid affects its charging ability.

For semi-conductive liquids, the rate of charge generation is critical, i. Low conductivity liquids are unable to dissipate the static charge. Static buildup can occur even if the vessel is earthed.

Conductivity is a factor of temperature; hence the conductivity of a liquid will be lower when it is cold. Therefore it is important in a manufacturing process to measure the conductivity of a solvent when it is at its lowest temperature. The electrostatic hazard posed by non-conductive liquids such as hydrocarbons, aromatic solvents, and insulating oils to name but a few, can be decreased dramatically by increasing their electrical conductivity.

The conductivity of an insulating liquid can be increased by addition of an anti-static additive. The increased conductivity enables charge to be more readily dissipated from the liquid.

antistatic additives for solvents

The latest such additives have the advantage of very low dose rates, requiring the addition of only a few parts-per-million, and can increase the conductivity of an insulating liquid by several orders of magnitude, as well as being available in a food contact approved version. Handheld conductivity meters allow the conductivity to quickly and easily be checked to ensure target conductivity continues to be maintained after a period of time or downstream in the process.

This conductivity consideration gives an extra layer of protection against static electricity, helping to keep your plant, people, processes and business safe, and also helping to achieve ATEX compliance. Use of best handling practices in conjunction with anti-static additives can be effective at minimising the risks associated with generation of static electricity in moving liquids.

The conductivity of a liquid determines the rate at which generated static can be dissipated via grounding. Chemical Industry Journal. Overview of Mexican Chemical Regulations. ABB to deliver 10 million euros of production improvements.
