AFTC SGB
AFTC SGB is a double sided, closed cell acrylic foam tape with a permanent Acrylic Coating 40 adhesive system on both faces, available at 0.090″ thickness. It is designed for bonding high and medium energy substrates — including plastics, glass, steel, aluminum, and ceramics — and delivers a 90° peel adhesion of 20 lb/in with very high initial tack, very good plasticizer resistance, and excellent water, UV, and solvent resistance. When used in combination with application advice, training, and possible audits, AFTC SGB is rated for warranty applications up to 25 years.

- Long-term structural bonding of high and medium surface energy plastic components in assemblies qualified for warranty applications up to 25 years
- Attachment of glass elements to metal or composite frames in architectural, glazing, or façade assemblies requiring extended service life documentation
- Bonding of aluminum and steel substrates where differential thermal expansion, water resistance, and no bi-metal corrosion are service requirements
- Full-surface bonding of thin or textured substrates — including ceramics — in assemblies where elastic conformability must accommodate surface irregularities over time
- Replacement of mechanical fasteners — including rivets, screws, spot welds, and liquid adhesives — in fabricated assemblies with extended warranty requirements
Common industries: construction, glazing and fenestration, architectural fabrication, transportation, general manufacturing.
AFTC SGB is a warranty-grade double sided acrylic foam tape within the SG series, constructed with a conformable acrylic foam core coated on both sides with Acrylic Coating 40 permanent adhesive. What distinguishes SGB — and the SG series — from standard AFTC grades is the explicit warranty designation: in combination with application advice, training, and possible audits, this tape is qualified for use in warranty applications up to 25 years.
The tape accommodates differential thermal expansion between dissimilar materials, allows full-surface tension-free bonding of thin or textured surfaces, and is listed as suitable for replacing rivets, screws, spot welds, and liquid adhesives. UV, solvent, and water resistance are all rated excellent, and high impact resistance is maintained below 0°C. No bi-metal corrosion is noted as a product benefit.
Note: all “Black+” tapes have a gray core and black adhesive.
As a pressure sensitive adhesive, a minimum bond line pressure of 14.5 psi applied by hand roller or mechanical presser is required for full adhesion. For low surface energy substrates, primer use is recommended; the AFTC line requires up to 72 hours to reach end-strength without primer, which is reduced to approximately 20 minutes with a compatible primer. Shelf life is 18 months when stored in original packaging in a dry environment between 39.2°F and 100.4°F.
What differentiates AFTC SGB from standard AFTC grades such as AFTC 5391, which shares the same thickness?
AFTC SGB and AFTC 5391 are both 0.090" ±10% Acrylic Coating 40 tapes with a conformable acrylic foam core targeting high and medium surface energy substrates. The defining distinction of SGB is its warranty designation: in combination with application advice, training, and possible audits, it is qualified for warranty applications up to 25 years — a commitment not present on AFTC 5391 or any standard AFTC grade. SGB also explicitly rates water resistance and no bi-metal corrosion as product benefits.
Why is peel adhesion important when selecting an acrylic foam tape?
Peel adhesion — measured here at 20 lb/in per ASTM D3330 — determines how effectively the tape resists being peeled or lifted from a bonded substrate under service loading. For warranty-grade applications designed to perform for up to 25 years, sustained peel performance under long-term environmental exposure — including UV, water, and thermal cycling — is critical to the bond line's integrity throughout the warranty period.
What is the operating temperature range for AFTC SGB?
AFTC SGB has a minimum temperature resistance of -40°F, a long-term temperature resistance of 212°F, and a short-term temperature resistance of 320°F.
Is AFTC SGB suitable for outdoor or environmentally exposed environments?
The TDS rates AFTC SGB as having excellent UV resistance, excellent solvent resistance, and excellent water resistance, and notes that it maintains high impact resistance below 0°C. It is specifically designated as a warranty product qualified for applications up to 25 years in combination with application advice, training, and possible audits. No specific regulatory compliance standards are listed on the TDS.
How should AFTC SGB be specified?
Specify grade (AFTC SGB), thickness (0.090"), color (Black+), liner type (Red PE), dimensional tolerances, and finished format. Warranty applications require use in combination with application advice, training, and possible audits as noted on the TDS. Confirm minimum application temperature of 59°F can be met at time of bonding.
