SYSTEM OVERVIEW

General Information

The instructions outlined here describe how to use DuPont

Enerfoam

Professional Foam Sealant* to fill gaps and cracks

™

around the home.

Designed to form a durable, airtight and water-resistant seal

in gaps up to 3" (75 mm), Enerfoam

of cracks and voids, forming a permanent, airtight and water-

resistant bond to wood, brick, vinyl, foam board, metal and most

plastics.** Once cured, it remains soft and flexible, permitting

natural expansion and contraction of surrounding surfaces.

In the U.S., Enerfoam

™

is also recognized as an effective fireblock

penetration sealant. Applications include adhering insulated

concrete forms, architectural foam and drywall, and sealing

cracks and voids such as pipe penetrations. The foam expands

only enough to generate an effective seal, retaining elasticity as

the structure expands and compresses. To determine the amount

of Enerfoam

required for an application, see Table 1.

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.

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).

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.
