What is an Emitter?

Emitters are devices that contain patented compounds called rust blocker VpCIs which evaporate (emit) into the surrounding enclosure or package. This is much like water as it evaporates but it takes place over months or years instead of minutes or hours.

How does an Emitter or VpCI work?

The chemicals that vaporize are special compounds that form a very thin layer, on the surface as they interact with all metals present. These chemicals form an ionic bond on the surface of the metal. They neutralize these ions and therefore prevent the interaction of air and water moisture with the metal, which in turn slows and stops the corrosion process.

Are Emitters environmentally safe?

Bull Frog emitters are very environmentally friendly and contain non known environmentally restricted or harmful compounds. Bull Frog’s position on the environment is well documented. Environmentally safe production is assured under ISO 14001 (environmental impact) standards.

How are Emitters used?

Emitters are used to protect enclosed metal components from corrosion by placing one or more of the devices into a container, package, or other enclosure. This includes all types of electronics, computers, electronic devices, electrical switches, electronic gear aboard ships and RVs, toolboxes, spare parts boxes and storage units, fuse boxes, telecommunications devices, such as cell phones, analytical equipment, gun safes, and cabinets, as well as any enclosure that contains metals that will corrode.

Why Use Emitters?

Emitters will save money (and time) for almost anyone using consumer electronics, electrical tools, and any consumer product which contains vulnerable metals. Emitters reduce corrosion that affects product quality and useful longevity in several ways:

• Emitters reduce electrical/ electronic failures in relays, switches, and connectors by preventing corrosion, -the number one cause for failure of electronic and electrical devices.
• Reduce maintenance by reducing failures and parts replacement.
• Extend equipment lifetime.
• Improve electrical reliability by reducing noise levels, and increasing switch reliability and continuity.
• Reduce the accumulation of contaminants. The quality and performance of electronic devices will also improve in that they will look cleaner, function more reliably.

How Long Does it Take for an Emitter to Become Effective?

This depends on the size, shape, and temperature of the enclosure. In general, at room temperature, emitters begin working immediately for metals immediately adjacent to them. It may require as much as 24 hours for metals at the extreme ends and internal spaces to become saturated with VpCI vapors.

How Can Emitters be Made Effective Sooner?

This can be done in several ways:

• By using more than one emitter and locating them at each end or along each edge of the enclosure.
• By spraying the entire area initially with one of our other Bull Frog products, such as Bull Frog Rust Blocker or Lubricant.
• By treating the item with our Bull Frog Cleaner/ Degreaser before placing them into the container or enclosure.
• By increasing the temperature of the parts or atmosphere.

How Many Times Can a Container Be Opened and Closed Before Depleting the VpCIs?

This depends on the chemical contaminants in the atmosphere. Under normal circumstances, if all of the vapor is lost from the container and all of the vapor is desorbed from all of the components in the container, the container can be opened and closed approximately 400 times or 10 times a day for one year!

What’s The Best Way To Prepare Metals For Long Term Storage, Using Bull Frog VpCI Protection?

These steps offer easy, safe, effective, and economical corrosion protection. You can expect better protection of metal surfaces using the following guidelines.

1. Clean your item, preferably with Bull Frog Cleaner Degreaser.
2. Be sure the item is free of fingerprints, oils, and acid or alkali residue.
3. Protect your item of concern with A Bull Frog Rust Blocker product as soon after cleaning as possible.
4. Keep the Bull Frog emitters as close to the product surface as possible, within 12″ maximum. Use at least 1-3″ strip for every square foot of metal surface protected, and a minimum of 1 square foot for every cubic foot of void space.
5. Place nothing between the metal surface protected and VpCI Emitter. Also, in order to prevent loss of the protective vapor, the item must be completely enclosed.
6. Seal your item airtight, if you need long-term storage of up to 10 years!
7. You can use VpCI emitters anywhere you need them, as a wrap, as insert strips and cups.
