Dow ENERFOAM Istruzioni operative

The instructions outlined here

describe how to use ENERFOAM™

Professional Foam Sealant to ﬁll

gaps and cracks around the home.

Designed to ﬁll gaps up to 3" (75

mm), ENERFOAM™ Professional

Foam Sealant expands to take the

shape of cracks and voids, forming

a permanent, airtight and water-

resistant bond to vinyl, wood and

metal surfaces.* Once cured, it

remains soft and ﬂexible, permitting

natural expansion and contraction

of surrounding surfaces.

To determine the amount of

ENERFOAM™ Professional Foam

Sealant required for an application,

see Table 1.

PREPARATION

1. Read and follow the Safety and

Conditions of Use instructions

below. Wear gloves, safety

glasses or goggles and

long sleeves. Provide good

ventilation and eliminate all

sources of ignition.

2. Shake can vigorously for 1

minute before dispensing and

between uses.

3. Gun-applied version: Invert can

and screw foam dispensing gun

assembly ﬁrmly onto valve as

shown in Figure 1. Screw until

ﬁnger-tight; do not overtighten

(Figure 2). When changing cans

using the foam dispensing gun,

tighten the ﬂow control knob

before removing the empty can

(Figure 3). Use gun cleaner,

acetone or other adhesive

remover to remove any residual

foam from the attachment area

before attaching fresh can.

Straw-applied version:

Attach the nozzle by twisting it

clockwise into the valve.

*For cavities, cracks and penetrations larger than 3" (75 mm), Dow recommends FROTH-PAK™ Foam Sealant or FROTH-PAK™ FS Foam Insulation. For window and door framework, minimal-expanding GREAT STUFF PRO™

Window & Door Insulating Foam Sealant is proven not to distort or bow the framework, when properly applied.

APPLICATION

GUN-APPLIED VERSION:

1. Adjust ﬂow control screw on

back of gun to an open position.

Immediately press trigger to ﬁll

gun with foam while dispensing

into an appropriate waste

receptacle.

2. Keeping can inverted, insert

applicator nozzle into the

penetration to be ﬁlled and

begin dispensing foam slowly.

Fill gap less than 1/3 full to

allow for proper expansion.

3. The foam dispensing gun is

recommended to control size

of the foam bead (from 1/8"

to 3" [3 mm to 75 mm]). This

is achieved by squeezing the

trigger on the foam dispensing

gun or by adjusting the ﬂow

control knob on the back of the

gun to set how far the trigger

can be pulled (Figure 5).

CAUTION:

Do not inject the foam sealant

into blind six-sided cavities, such

as window mullions. The foam

must be exposed to atmospheric

moisture to thoroughly cure.

TIP: Using grease or petroleum

jelly in the adapter of the gun

may reduce possibility of foam

gluing the can on the gun.

TIP: Apply foam in a continuous

bead, with no voids or breaks, to

achieve an effective seal.

*Foam should only be dispensed around the outside of the box, not inside.

4. If the gap is overﬁlled, stuff

excess cured foam into the gap

with a blunt tool or trim away

with a sharp knife. 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.**

5. Clean foam dispensing gun

periodically by rubbing the end

on soft wood to free it from

foam. Do not use a sharp object

to clean foam dispensing gun.

Use a solvent cleaner such as

gun cleaner, acetone or other

adhesive remover between

extended periods of non-use.

6. To store partially used can,

tighten ﬂow control screw

closed and store can upright

with gun attached. Use can

within 30 days of initial use.

7. To reuse, shake can vigorously

for 1 minute before dispensing

and follow dispensing

instructions stated above.

STRAW-APPLIED VERSION:

1. Attach the nozzle by twisting it

clockwise into the valve. Press

the button until the appropriate

size of foam bead is achieved.

Fill gap less than 1/3 full to

allow for proper expansion.

2. If the gap is overﬁlled, stuff

excess cured foam into the gap

with a blunt tool or trim away

with a sharp knife. 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.**

3. Clean straw periodically by

rubbing the end on soft wood to

free it from foam.

4. When ﬁnished, bend the straw

back onto the plug on top of

the trigger assembly. The plug

prevents moisture from entering

and curing inside the straw or

valve.

5. To use after storage, gently

rotate or twist the straw to break

the adhesive bond of the foam.

Pull the straw off of the plug and

dispense.

CLEANUP

• Onsolidsurfaces,uncured

foam can be dissolved with

gun cleaner, acetone or other

adhesive remover. Cured foam

must be mechanically removed

or allowed to wear off in time.

• Tocleanfoamdispensinggun,

install a can of gun cleaner,

acetone or other adhesive

remover to the foam dispensing

gun and spray until all foam

is blown out of the foam

dispensing gun 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.

• Donotleaveacanofcleaner

mounted on the foam

dispensing gun. This will

dissolve the lip seals inside

the gun and render it useless.

Foam escaping at the handle or

trigger indicates a faulty seal. If

this happens, the gun should be

replaced. If the foam dispensing

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.

DISPOSAL

• Disposaloffullorpartially

used aerosol cans must be in

compliance with all federal,

state/provincial and local laws

and regulations. Regulations

vary in different locations.

Empty cans are not considered

hazardous waste and may be

disposed of an nonhazardous

household waste.

SAFETY AND

CONDITIONS OF USE

• ReadthelabelandMaterial

Safety Data Sheet carefully

before use.

• ENERFOAM™Professional

Foam Sealant 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™Professional

Foam Sealant 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™Professional

Foam Sealant 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 perfor-

mance.

• 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foamdispensingguns

(shown in Figure 1) simpliﬁes

the application of ENERFOAM™

Professional Foam Sealant. 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.
