The drying time for liquid paints (waterborne and solvent-borne) can vary depending on several factors such as the type of paint, the thickness of the coating, the temperature, and the humidity.

Waterborne paints typically dry faster than solvent-borne paints. They can dry to the touch within minutes and be recoated within an hour. However, it is recommended to allow 24 hours before allowing normal use.

Solvent-borne paints, on the other hand, can take longer to dry. They typically dry to the touch within a few hours, but can take up to 24 hours to fully cure and harden. It is recommended to allow at least 24 hours before allowing normal use.

It’s important to note that these are general guidelines and the actual drying time may vary depending on the specific paint, the application method, and the environmental conditions. It is always recommended to consult the manufacturer’s instructions for more detailed information on the drying time for a specific paint

In addition to the drying time, using a curing oven can also accelerate the drying and hardening process of liquid paints, both waterborne and solvent-borne. A curing oven uses heat to dry and cure the paint, which can significantly reduce the overall curing time. The curing temperature and time will depend on the type of paint and coating being used, as well as the desired level of cure. For example, a liquid coating such as a polyurethane coating will typically require a higher curing temperature and longer curing time than an epoxy coating.

It’s important to note that not all paints and coatings can be cured in an oven, and some may require specific curing conditions such as humidity or UV light. It is always recommended to consult the manufacturer’s instructions for more detailed information on the curing requirements for a specific paint or coating.

When using a curing oven, it’s important to pay attention to the temperature and time settings to ensure that the paint or coating is cured properly. The curing temperature can range from around 150F to 400F, depending on the type of paint or coating being used. The curing time can also vary, with some paints or coatings requiring only a few minutes while others may require several hours.

It’s also important to monitor the curing process to ensure that the paint or coating is not overheated, as this can cause discoloration, bubbling, or other defects in the final coating. It’s also important to make sure that the oven is properly ventilated to remove any solvents or fumes that may be emitted during the curing process.

Additionally, for some paints or coatings, it’s important to also consider the environment where the curing oven is located, because high-temperature and humidity can cause issues such as cracking, sagging, and wrinkling.

In summary, it’s important to follow the manufacturer’s instructions for the specific paint or coating being used to ensure that it is cured properly and to avoid any issues with the final coating.

OTSON electrostatic spray systems are designed to work with a wide range of paint and coating types, including those with high and low resistivity/conductivity. However, certain paint types may require additional preparation or equipment adjustments to ensure proper application and finish quality.

  • Highly conductive paints, such as waterborne paints, can be more challenging to spray electrostatically due to their high electrical conductivity. These types of paints can cause electrical charges to travel back through the paint supply system, potentially causing damage to the equipment or even electrical shocks to the operator. To prevent these issues, special equipment, such as an isolation stand or voltage-blocking system, may be required. OTSON team is available to assist customers in determining the appropriate equipment and adjustments for their specific coating needs.
  • Lowly conductive paints, such as solvent-borne paints, can also pose challenges for electrostatic spraying due to their low electrical conductivity. These types of paints may require modifications to increase their conductivity, such as the addition of polar solvents or conductive pigments. In addition, viscosity corrections may also need to be made to ensure coating droplets are fine enough.

Resistivity and conductivity are two important parameters that describe the electrical properties of a material. Resistivity is a measure of a material’s resistance to electrical current flow, while conductivity is a measure of a material’s ability to conduct electrical current. The inverse of resistivity is conductivity.

In general, materials that have high resistivity have low conductivity, and vice versa. For example, materials such as rubber and plastic have high resistivity and low conductivity, while materials such as copper and aluminum have low resistivity and high conductivity.

Resistivity and conductivity are related properties that describe how easily an electric current can flow through a material. Resistivity is a measure of how difficult it is for an electric current to flow through a material, and is typically measured in ohm-meters (m). The higher the resistivity, the more difficult it is for an electric current to flow through the material. On the other hand, conductivity is a measure of how easily an electric current can flow through a material, and is typically measured in siemens per meter (S/m). The higher the conductivity, the more easily an electric current can flow through the material.

For OTSON electrostatic spray systems, the resistivity/conductivity range is typically between 20Mm to 30Mm. Paints and coatings that fall within this range have the appropriate conductivity to allow the electrostatic charge to flow through the paint, while not being too conductive that the charge tracks back to the ground through the paint system supply. Coatings with lower resistivity/conductivity may require additional treatment or modification to increase the resistivity/conductivity.

It’s important to note that while conductivity is a desirable property in electrostatic spraying, it is not the only factor that determines the quality of the finish. Other factors such as viscosity, surface tension, and solvent evaporation also play a role in the quality of the finish. OTSON team can assist customers in selecting the appropriate coating and making any necessary modifications to ensure optimal performance in the electrostatic spray system.

In summary, resistivity and conductivity are two important parameters that describe the electrical properties of a material and play a crucial role in electrostatic spray systems. The OTSON Electrostatic Spray System is able to work with a wide range of paint resistivity/conductivity, but adjustments can be made to the paint to ensure optimal coating transfer efficiency.

OTSON electrostatic spray systems are designed to handle a wide range of resistivity/conductivity levels in paints and coatings. The OTSON electrostatic spray system is able to handle a resistivity/conductivity range of 20M ohm to 30 M ohm to obtain an appropriate charge. However, if a coating falls outside of this range, changes can be made to make the coating more conductive, including solvent additions, changes in solvent composition, and the use of polar solvents. Additionally, viscosity corrections may also need to be made to ensure coating droplets are fine enough. It’s important to note that the conductivity of the paint or coating is an important factor in electrostatic spraying, and it is always recommended to consult the manufacturer’s instructions for the specific paint or coating being used to determine the appropriate resistivity/conductivity requirements. OTSON team is also available to assist customers in determining the appropriate resistivity/conductivity for their specific coating needs.

It’s important to note that OTSON electrostatic spray systems are designed with flexibility in mind, and can be easily adjusted to accommodate a wide range of paint and coating types. The OTSON team is always available to assist customers in determining the appropriate equipment and adjustments for their specific coating needs, which includes the resistivity/conductivity of their paint.

5 Questions on Effective Enhanced Cleaning in Senior Living Facilities

5 Questions on Effective Enhanced Cleaning in Senior Living Facilities

Illness-causing germs and viruses like SARS-CoV-2 (the virus that causes COVID-19) can quickly spread on surfaces leaving your residents, staff and visitors at risk. Manual cleaning methods and traditional disinfecting tools aren’t designed to effectively reach all areas. Enhanced disinfection solutions like electrostatic cleaning can help protect residents and increase staff efficiency by eliminating germs on high-touch surfaces in a fraction of the time.

Included below are five common questions about electrostatic cleaning and tips for how to elevate cleaning and disinfecting in your Senior Living facilities.

1. How does an electrostatic disinfectant sprayer work?

Most surfaces in your community are neutral or negatively charged. This is not important in relation to manual disinfection application. But electrostatic disinfectant sprayers positively charge an antimicrobial liquid as it passes through the nozzle. These positively charged antimicrobial droplets are then attracted to those surfaces and wrap around the application surface allowing for improved coverage on hard, nonporous environmental surfaces. This helps ensure full coverage and avoids liquid pooling, saving you time, solution and money.

2. Why do healthcare and Senior Living facilities benefit from electrostatic cleaning?

According to a recent study: after minimal manual precleaning of areas with visible soiling, application of a dilute sodium hypochlorite disinfectant using an electrostatic sprayer provided rapid and effective decontamination.1

As with other healthcare settings, Senior Living facilities benefit from the ease and effectiveness of electrostatic cleaning because of:

  • Large spaces – electrostatic disinfectant sprayers can apply more disinfectant solution in less time than traditional cleaning methods
  • Vulnerable population – the need to protect high-risk seniors from potentially deadly viruses like SARS-CoV-2 is great
  • Human error – even the best-trained cleaning staff occasionally miss a spot or inadequately disinfect a surface, and an electrostatic disinfectant sprayer makes up for those natural human mistakes

3: Where do I apply electrostatic cleaning in my community?

Electrostatic disinfection is applicable for hard nonporous surfaces anywhere residents, staff and visitors congregate and germs can manifest. Examples include the following:

Resident Room and High-Touch Areas

  • Light switches
  • Nurse call cords
  • Railings/handrails
  • Door handles
  • Wheelchairs
  • Bedrails
  • Tables and chairs

Common Areas
