Dual LockReclosable Fasteners

with Acrylic Foam Tape

Summary

Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA)

and water*prior to applying 3M™Dual Lock™Reclosable Fasteners.

Exceptions to this general procedure that may require additional surface preparation include:

•Heavy Oils: A degreaser or solvent-based cleaner may be required to remove heavy oil or

grease from a surface and should be followed by cleaning with IPA/water.

•Abrasion: Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt

or oxidation and can increase surface area to improve adhesion.

•Adhesion Promoters: Priming a surface can significantly improve initial and ultimate

adhesion to many materials such as plastics and paints.

•Porous Surfaces: Most porous and fibered materials such as wood, particleboard, concrete,

etc. need to be sealed to provide a unified surface.

•Unique Materials: Special surface preparation may be needed for glass and glass-like

materials, copper and copper containing metals and plastics or rubber that contain

components that migrate (e.g. plasticizers).

General

Procedure

•The Dual Lock reclosable fasteners and substrates should have equilibrated for a minimum

of one hour at temperatures of 68°to 80°F (20°to 27°C) before application.

•To obtain optimum adhesion, the

bonding surfaces must be well unified

(see porous surfaces above), clean and

dry. Typical surface cleaning solvents

are IPA/water mixture (rubbing alcohol)

or heptane.*(Steps A and B.)

•Application Procedure: Bond strength

is dependent upon the amount of

adhesive-to-surface contact developed.

Firm application pressuredevelops better

adhesive contact and helps improve bond

strength. (Steps C and D.)

*Note: These cleaner solutions contain greater than 250 g/l of volatile organic compounds (VOC). Please consult your

local Air Quality Regulations to be sure the cleaner is compliant. When using solvents, extinguish all ignition sources,

including pilot lights, and follow the manufacturer’s precautions and directions for use. Be sure to follow all government

regulations and the manufacturer’s precautions and directions for use when using solvents or other cleaning methods.

General Procedure

(continued)

•3M™Dual Lock™Reclosable Fastener Application Procedure:

°

For small pieces: The liner is removed from the Dual Lock reclosable fastener

adhesive. Without touching the adhesive, the Dual Lock reclosable fastener is

applied to the surface using light finger pressure. The Dual Lock reclosable

fastener must then be rolled down with a rubber-covered hand roller, being

careful not to crush the Dual Lock reclosable fastener stems. It is suggested to

roll down the Dual Lock reclosable fastener at least once in each direction with

a 4.5 lb. to 10 lb. roller to insure 100% adhesive contact, especially around the

perimeter of the part.

°

For long strips: Theliner is removed from the Dual Lock reclosable fastener

adhesive. Without touching the adhesive, the Dual Lock reclosable fastener is

aligned on the substrate surface. One end of the Dual Lock reclosable fastener

strip is pressed down (tabbed) to the substrate while holding the other end of

the strip under light tension. The Dual Lock reclosable fastener strip is then

slowly rolled down the entire length of the strip from the tabbed end with a

rubber covered hand roller, taking care not to trap air bubbles under the

adhesive and not to crush the Dual Lock reclosable fastener stems. It is

suggested to roll down the reclosable fastener at least once in each direction

with a 4.5 lb. to 10 lb. roller to insure 100% adhesive contact, especially around

the perimeter of the part.

•Evaluate Application Procedure: A Clear Test Panel (Glass, Acrylic, or

Polycarbonate) can be used to evaluate and improve application procedure. Using

the above procedure, apply the Dual Lock reclosable fastener to a Clear Test

Panel. After Dual Lock reclosable fastener has been applied, examine the back

side of the panel for adhesive wet out (contact area). It is important to adjust

application procedure and roll down to insure almost 100% contact, especially

around the perimeter of the parts.

•The pressure-sensitive adhesive bonds to the substrate on contact and parts can be

handled immediately. Adhesive bond strength increases with time, pressure and

temperature. A minimum of twenty four hours dwell time is recommended before

applying a load or disengaging assembled parts.

Heavy Oils

On surfaces with a light oily film, or other light contamination, the 50:50 IPA/water solution is usually

adequate. Where heavy oils or grease are present, a “degreasing” solvent such as 3M™Prep Solvent 70,

3M™Citrus Base Cleaner, mineral spirits, naphtha or similar solvents are suggested to cut the oil. This

should always be followed with an IPA/water cleaning to help ensure that any residue or film is removed.*

Abrading a surface can serve several functions:

•Remove heavy levels of dirt or oxide from metals or paints (e.g. galvanized steel).

•Create additional surface area that can increase adhesion.

•Smooth a surface to obtain more flatness, allowing improved contact area.

Abrasion often helps adhesion to paints and plastics. When abrading, it is important for tapes to have a

finely abraded surface. Very small scratches in the surface, generated with circular motion rather than

straight-line motion, are most desirable. A surface with many micro-scratches in it can have up to 40%

additional available surface area, translating to higher ultimate strength and greater initial adhesion.

Scotch-Brite

®

Hand Pads (such as 7447 Maroon or Heavy Duty Green) are good for achieving the right

level of abrasion. Tools such as a power palm sander will assist on large jobs. Avoid grinding a surface

with coarse abrasive materials, since they may create too rough of a texture for the adhesive to

adequately flow into the surface. Always clean the surface with the IPA/water solution or additional

methods previously described, and be certain that all loose particles are removed prior to bonding.

Priming a surface can significantly improve initial and ultimate adhesion to many materials such as

plastics and paints because of their low surface energy or the additives they may contain. A primer

creates a new surface for 3M™Dual Lock™Reclosable Fasteners to adhere to and can also create a

layer that may impede the migration of additives that may be present in a material. If needed for LSE

and difficult to bond to substrates, lightly abrading a surface with Scotch-Brite

®

Hand Pad prior to

applying the adhesion promoter can sometimes improve its bond performance to the substrate. It is

important for the user to determine the suitability of the Dual Lock reclosable fastener, the adhesion

promoter and the application process. Consult Technical Data Sheet on individual promoters for

suggested application procedure.

Rough, porous or fibered materials such as wood, particleboard, cement, etc., have an open surface and

require sealing to provide a unified surface for tape bonding. Common sealing materials would include

paint, varnish or other hard surface coatings. Fast drying 3M™Rubber & Vinyl 80 Spray Adhesive can

also be used to unify the surface and improve the tape bond.

Glass, stone, ceramic or other siliceous materials are hydrophilic (water-loving) by nature. Normally, the

hydrophilic nature makes pressure sensitive adhesive bond durability susceptible to change under high

humidity or exposure to moisture. In basic terms, water vapor can undercut the tape bond and interfere

with the normal adhesion forces. Silane coupling agents, added to the IPA/water cleaning solution, can

help reduce the “water-loving” tendency of these surfaces and enhance the tape bond in high moisture

environments.

Copper, brass, and bronze are prone to oxidation even after the Dual Lock reclosable fasteneris applied.

To prevent a weakening of the bond, a lacquer or varnish should be applied to these surfaces. Be sure to

test the tape bond to the sealer on a metal surface to verify good adhesion.

Flexible PVC (vinyl) contains plasticizers that can migrate into the tape and affect adhesion. The Dual

Lock reclosable fasteners with Multi-Purpose 1 or 2 Acrylic Adhesivesare formulated to be resistant

to plasticizer migration, or 3M™Adhesive Promoter 2262AT can serve as a barrier to migration.

Rubber materials (e.g. EPDM, neoprene) can have low surface energy and may also contain plasticizers

and oils. These require the use of an adhesion promoter for stable bond strength. Test for compatibility

with flexible PVC and rubber materials by aging bonded samples for a week at 150°F (66°C) and

check for softening of the adhesive, discoloration or reduction in bond strength.

Run an Evaluation

Because 3M cannot anticipate all of the different possible surfaces and contaminants

that may exist, it is imperative that the user conduct an evaluation to determine the

suitability of 3M™Dual Lock™Reclosable Fasteners, surface preparations

procedures, and any other processes that may have an influence on the tape or the

bonded parts. Likewise, where there are any changes in plastic or paint formulation,

or suppliers of these materials, it is advisable to run evaluations to ensure that the

change has not influenced the compatibility of the surface with Dual Lock reclosable

fasteners.
