Use Peel & Stick Fasteners for small and medium size filters or in areas where use of screws are simply too risky or, on large filter installations as a method of perfectly aligning the fasteners and grommets for screw mounting.
THIS NEW AND INNOVATIVE FASTENER IS AN INSTALLATION
The following video shows a satisfied customer mounting Air Solution Company’s Residential Filter Screen using PEEL & STICK twist lock fasteners. Can also be used on other filter grades including Std. Duty, Med. Duty, Fine Mesh and HD Commercial Grade Filters.
PEEL & STICK Fasteners Explained.
The New Peel and Stick Quick Release Twist Lock Fastener is designed to provide very high surface bonding strength when attached to the following substrates:
- galvanized steel
- Stainless Steel
- enameled steel
- Polybutylene Terephythalate,
- Rigid PVC, ABS
- acrylic / polyurethane paint,
- powder coat painted surfaces
- Polyester / Epoxy paint
Applying Peel and Stick Fasteners
Ideal Application Temperature Range: 70°F to 100°F (21°C to 38°C). Pressure sensitive adhesives on the bottom of the Peel and Stick Twist Lock Fasteners use viscous flow to achieve optimal substrate contact.
To obtain good performance it is important to ensure that the surface is dry and free of moisture.
Minimum Recommended Application Temperatures: 50°F (10°C) Application to surfaces at temperatures below the minimum is not recommended because the adhesive becomes too firm to adhere readily. However, once properly applied, the holding strength in the operational temperature range should be satisfactory.
Operational Temperature Range When Fully Cured: -31°F to 194°F (-35°C to 90°C).
Preparing Attachment Surface: Most substrates are best prepared by cleaning with a 50:50 mixture of 90% isopropyl alcohol (IPA*) and water prior to applying the fasteners – Please note that a 50/50 IPA & water solution is actually more effective than a straight IPA solution because the water reduces the evaporation rate which increases the solution dwell time with the surface grime thus increasing its solvency for better cleaning. If using a straight concentration of IPA (without water) to clean the surface, be sure to wipe it a couple of times as a straight IPA concentration evaporates almost immediately and may not completely dissolve the surface grime ; Also, Do not to smoke or be near an open flame during application as a non-watered IPA solution may be flammable. Special surface preparation may be needed for copper and copper containing metals, and plastics or rubber that contain components that migrate (e.g. plasticizers).
Application Pressure: Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure develops better adhesive contact and helps improve bond strength. Typically, good surface contact can be attained by applying enough pressure to insure that the tape experiences approximately 15 psi (100 kPa) pressure. Note: non-rigid surfaces may require 2 or 3 times that much pressure to make the tape experience 15 psi. Applying to heavily textured surface reduces the adhesive to surface contact so it is important to press the fastener firmly against the slightly textured surface to ensure there is sufficient adhesive “wet-out” to migrate into the textured area. Heavily textured and grooved surfaces are not recommended for attachment points. Exceptions to the general procedure that may require additional surface preparation include:
• 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 Strength: After application, the bond strength will increase as the adhesive flows onto the surface (also referred to as “wet out”). At room temperature approximately 50% of ultimate bond strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. This flow is faster at higher temperatures and slower at lower temperatures. Ultimate bond strength can be achieved more quickly (and in some cases bond strength can be increased) by exposure of the bond to elevated temperatures (e.g. 150°F [66°C] for 1 hour). This can provide better adhesive “wetout” onto the substrates. Abrasion of the surfaces or the use of primers/ adhesion promoters can also have the effect of increasing bond strength and achieving ultimate bond strength more quickly. When mounting the filters simultaneously with the attachment of the Peel and Stick fasteners, only apply enough tension as to pull the filter so it is lightly taught as there is no need to pull the filter excessively tight across the intake opening, If the filters have a crease across the face when removed from the shipping carton, the warmth from the sun will eventually cause the wrinkles to release – pulling the filter excessively taught isn’t necessary and will over torque the adhesive bond.
Adhesion Promoters: Priming a surface can significantly improve initial and ultimate adhesion to many materials such as plastics and paints – The recommended adhesive promoter for Peel and Stick Fasteners is 3M Primer 94 which is available from industrial supply stores (eg., Fastenal, etc) or purchase on-line.
• 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 copper and copper containing metals, and plastics or rubber that contain components that migrate (e.g. plasticizers).
Speedy Installation – It’s as Simple as 1 – 2 – 3
- First insert the Peel and Stick fasteners into the grommets on the filter – Insert from the back side of the filter.
- Peel and Stick the Corner fasteners in their mounting location such that all fasteners located between the corners are in alignment with their attachment location.
- Now Peel and Stick the remaining fasteners around the Perimeter. This method of fastener to grommet alignment is unmatched in the industry – It helps ensure a perfect alignment. For maximum strength you can screw the perfectly aligned fasteners in onto the unit.
