Safety and Conditions of Use
• Read the label and Material Safety Data Sheet carefully
before use.
• Enerfoam
™
contains isocyanate and a flammable blowing
agent. Vapor may travel to other rooms. Ensure adequate
ventilation. Shut off all pilot lights and extinguish open flames;
eliminate all sources of ignition before use. Do not smoke or
use lighters or matches while dispensing foam.
• Do not breathe vapor or mist. Use in well-ventilated areas
or wear proper respiratory protection. Isocyanate is irritating
to the eyes, skin and respiratory system, and may cause
sensitization by inhalation or skin contact.
• Enerfoam
™
is very sticky and will adhere to most surfaces
and skin. Do not get foam on skin. Wear long sleeves,
gloves, and goggles or safety glasses. Cured foam must
be mechanically removed or allowed to wear off in time.
• The contents are under pressure. The can may burst if left
in areas susceptible to high temperatures, such as motor
vehicles, or near radiators, stoves or other sources of heat.
Do not place can in hot water. Do not puncture, incinerate
or store at temperatures above 120°F (49°C).
• Enerfoam
™
may be used on vinyl, wood, composite and
metal (aluminum or steel) substrates. The product adheres
best when surfaces are clean and free of oil or chemicals.
• Extremely cold temperatures can affect dispensing
performance.
• Skin of cured foam can discolor if exposed to direct or
continuous sunlight for 24 hours or more. Foam should
be painted or coated if prolonged exposure to sunlight is
expected.
• Using one of the PRO Series foam dispensing guns
(shown in Figure 1) simplifies the application of Enerfoam
™
.
In addition to enabling pinpoint application control, an
airtight and moisture-tight seal between the gun and the
can prevents the foam from curing and blocking the
dispensing valve.

The DuPont™ Enerfoam™ Professional Foam Sealant is a versatile product designed for sealing gaps and cracks around the home, forming a durable, airtight, and water-resistant seal. It is suitable for gaps up to 3 inches (75 mm) wide. This foam sealant expands to conform to the shape of cracks and voids, creating a permanent, airtight, and water-resistant bond to various substrates including wood, brick, vinyl, foam board, metal, and most plastics. Once cured, the foam remains soft and flexible, allowing for natural expansion and contraction of surrounding surfaces without compromising the seal.

In the U.S., Enerfoam™ is recognized as an effective fireblock penetration sealant, making it suitable for applications such as adhering insulated concrete forms, architectural foam, and drywall, as well as sealing pipe penetrations and other cracks and voids. The foam's expansion is controlled to ensure an effective seal while maintaining elasticity.

Technical Specifications and Yields:

The product is available in different can sizes, offering varying yields and caulk equivalencies:

• 24 oz (680 g) can (Reusable straw delivery): Yields approximately 775 linear feet (236 m) of 3/8" (1 cm) diameter bead, equivalent to about 18 quart tubes of caulk.
• 24 oz (680 g) can (Gun delivery): Yields approximately 970 linear feet (296 m) of 3/8" (1 cm) diameter bead, equivalent to about 22 quart tubes of caulk.
• 30 oz (850 g) can (Gun delivery): Yields approximately 1,450 linear feet (442 m) of 3/8" (1 cm) diameter bead, equivalent to about 33 quart tubes of caulk. These yields are estimated under ideal conditions.

Usage Features:

The Enerfoam™ Professional Foam Sealant can be applied using either a reusable straw or a PRO Series foam dispensing gun (e.g., Pro 13, Pro 14, Pro 15 models). The gun-applied version offers enhanced control and precision.

Preparation for Use:

1. Safety First: Always read and follow the Safety and Conditions of Use instructions and the Material Safety Data Sheet (MSDS) carefully before use. Wear long sleeves, gloves, and goggles or safety glasses.
2. Ventilation: Ensure adequate ventilation in the work area.
3. Ignition Sources: Eliminate all sources of ignition, including pilot lights, open flames, lighters, and matches. Do not smoke while dispensing foam.
4. Shaking: Shake the can vigorously for 1 minute before dispensing and between uses to ensure proper mixing of contents.

Gun-Applied Version Instructions:

1. Assembly: Invert the can and firmly screw the foam dispensing gun assembly onto the valve until finger-tight (do not overtighten).
2. Flow Control: Adjust the flow control screw on the back of the gun to an open position.
3. Priming: Immediately press the trigger to fill the gun with foam, dispensing into an appropriate waste receptacle.
4. Application: Insert the applicator nozzle into the penetration to be filled. Begin dispensing foam slowly, filling gaps less than 1/3 full to allow for proper expansion. Apply foam in a continuous bead to achieve an effective seal, avoiding voids or breaks. The gun allows for precise control of the foam bead size (from 1/8" to 3").
5. Curing: Foam will be tack-free in less than 20 minutes and can be trimmed in 1/2 hour. It is fully cured 1 hour after application (dependent on temperature, relative humidity, and foam bead size).
6. Overfilling: If a gap is overfilled, excess cured foam can be stuffed into the gap with a blunt tool or trimmed with a sharp knife.

Straw-Applied Version Instructions:

1. Assembly: Attach the nozzle by twisting it clockwise into the valve.
2. Application: Press the button until the appropriate size of foam bead is achieved. Fill gaps less than 1/3 full to allow for proper expansion.
3. Overfilling: Similar to the gun-applied version, overfilled gaps can be managed by stuffing or trimming excess cured foam.
4. Storage: When finished, bend the straw back onto the plug on top of the trigger assembly to prevent moisture from entering and curing inside the straw or valve.
5. Reuse: To reuse after storage, gently rotate or twist the straw to break any adhesive bond of the foam. Pull the straw off the plug and dispense.

Important Safety Considerations:

• Adhesion: Enerfoam™ is very sticky and will adhere to most surfaces and skin. Avoid contact with skin; wear protective clothing. Cured foam must be mechanically removed or allowed to wear off over time.
• Pressure: The contents are under pressure. The can may burst if left in areas susceptible to high temperatures (e.g., motor vehicles, near radiators, stoves, or other heat sources). Do not place the can in hot water, puncture, incinerate, or store at temperatures above 120°F (49°C).
• Substrates: The product adheres best to clean surfaces free of oil or chemicals.
• Temperature: Extremely cold temperatures can affect dispensing performance.
• Discoloration: Cured foam can discolor if exposed to direct or continuous sunlight for 24 hours or more. Paint or coat the foam if prolonged exposure to sunlight is expected.
• Isocyanate and Flammable Agent: Enerfoam™ contains isocyanate and a flammable blowing agent. Vapors may travel to other rooms. Do not breathe vapor or mist. Use in well-ventilated areas or wear proper respiratory protection. Isocyanate is irritating to the eyes, skin, and respiratory system, and may cause sensitization by inhalation or skin contact.
• Combustibility: When cured, these products are combustible and will burn if exposed to open flame or sparks from high-energy sources. Do not expose to temperatures above 240°F (116°C).

Maintenance Features (Clean Up & Disposal):

• Uncured Foam: On solid surfaces, uncured foam can be dissolved with DuPont™ Great Stuff Pro™ Foam Cleaner.
• Cured Foam: Cured foam must be mechanically removed or allowed to wear off over time.
• Cleaning the Dispensing Gun: To clean the foam dispensing gun, install a can of Great Stuff Pro™ Foam Cleaner onto the gun. Spray until all foam is blown out and only cleaner is visible (approximately half the can of cleaner will be used). Allow the gun to sit for several minutes and repeat with a second flush.
• Storage of Gun: Do not leave a can of cleaner mounted on the foam dispensing gun, as this will dissolve the lip seals inside the gun, rendering it useless. If the gun has not been cleaned, add a new can of Enerfoam™ Professional Foam Sealant immediately. If left without a can attached, exposure to air and moisture will cause the foam in the gun to cure.
• Storing Partially Used Cans (Gun-applied): Tighten the flow control screw closed and store the can upright with the gun attached. Use the can within 30 days of initial use. Always close the flow control knob when the gun is not in use.
• Cleaning the Straw (Straw-applied): Clean the straw periodically by rubbing the end on soft wood to free it from foam.
• Disposal: Disposal of full or partially used aerosol cans must comply with all federal, state/provincial, and local laws and regulations. Empty cans are considered nonhazardous household waste.

Note: For cavities, cracks, and penetrations larger than 3" (75 mm), DuPont recommends Froth-Pak™ Foam Sealant or Froth-Pak™ Foam Insulation. For window and door framework, minimal-expanding DuPont™ Great Stuff Pro™ Window & Door Polyurethane Foam Sealant is recommended to prevent distortion or bowing of the framework.
