Acrylic PSA (DP)
APSADP is a non-woven nylon supported acrylic/silicone differential laminating adhesive with acrylic adhesive (2 mils) on one face and silicone adhesive (2.5 mils) on the opposite face, carried on 4oz non-woven nylon. The acrylic side delivers 150–170 lb/in peel at 24-hour applied dwell (the highest peel value in the APSA family), and the silicone side delivers 60–80 lb/in peel across both immediate and 24-hour applied dwell. Continuous service temperature spans −65°F to 250°F with short-term capability to 350°F.

- Laminating of silicone rubber or silicone-coated substrates to metal, glass, or rigid plastic components
- Dual-surface bonding applications requiring compatibility with both silicone and polar substrates in a single differential construction
- Non-woven backed adhesive lamination for converting applications requiring conformable backing
- Low-temperature adhesive applications operating down to −65°F (wider than standard acrylic grades)
- Short-term high-temperature bonding up to 350°F where silicone contribution extends thermal range
Common industries: Industrial manufacturing, silicone rubber converting, specialty lamination, aerospace, electronics assembly.
APSADP is a differential double-sided laminating adhesive construction featuring an acrylic adhesive (2 mils ±10%) on one face and a silicone adhesive (2.5 mils ±10%) on the opposite face, supported by a 4oz non-woven nylon carrier with a 78# clay-coated kraft release liner.
The non-woven nylon carrier distinguishes APSADP from the cloth-supported APSAEP, providing different mechanical characteristics for applications requiring non-woven backing conformability while maintaining the differential acrylic/silicone adhesive architecture. The construction enables a single component to laminate simultaneously to silicone-compatible and polar substrate surfaces — a capability neither chemistry alone can provide.
Peel adhesion on the acrylic side is substantially higher than the silicone side, building from 40–60 lb/in at immediate application to 150–170 lb/in at 24-hour dwell — the highest peel values in the APSA family. The silicone side remains at 60–80 lb/in across both immediate and 24-hour applied dwell. Shear adhesion under a 1,000-gram load at 72°F is 24+ (hours inferred) on both faces per PSTC-107.
Continuous no-load service temperature is −65°F to 250°F, extending short-term to 350°F — both the low-temperature and high-temperature limits are broader than most adhesives in the product family, reflecting the silicone contribution to the differential construction. Minimum application temperature is 50°F. The TDS notes that actual service range temperatures depend on application because of the dual-chemistry construction.
What differentiates APSADP from APSAEP?
Both are differential acrylic/silicone laminating adhesives, but they use different carriers: APSADP uses a 4oz non-woven nylon backing, while APSAEP uses a 3.0 mil cloth carrier. Peel measurement units also differ between the two TDSs — APSADP reports lb/in while APSAEP reports oz/in, making direct peel comparison require unit conversion (150–170 lb/in on APSADP converts to approximately 2,400–2,720 oz/in, substantially higher than APSAEP's 80+ oz/in). APSADP also publishes broader service temperature range (−65°F to 250°F continuous vs. −40°F to 302°F for APSAEP's acrylic side) and explicit short-term capability to 350°F.
Why is peel adhesion important when selecting this adhesive?
For differential laminating adhesives, peel adhesion must be evaluated separately on each face because the two chemistries serve different substrate families. APSADP's acrylic side delivers 150–170 lb/in at 24-hour applied dwell — the highest peel value in the APSA product family — confirming aggressive bonding to polar substrates. The silicone side's consistent 60–80 lb/in at both immediate and 24-hour dwell indicates stable performance without significant bond build, typical of silicone PSA behavior.
What is the service temperature range for APSADP?
APSADP has a continuous no-load service temperature range of −65°F to 250°F, with short-term no-load capability to 350°F. Minimum application temperature is 50°F. The TDS notes that actual service ranges depend on application due to the acrylic/silicone combination chemistry.
Is APSADP suitable for low-temperature or short-term high-temperature environments?
Yes. The −65°F continuous low-temperature limit is one of the widest in the APSA family, supporting cold-service applications, and the 350°F short-term capability extends well beyond typical acrylic limits due to the silicone adhesive contribution. No specific regulatory compliance standards are listed on the TDS for this material.
How should APSADP be specified?
Specify adhesive designation (APSADP / Acrylic PSA DP), orientation (acrylic side to polar substrate / silicone side to silicone substrate), adhesive thicknesses (2 mils acrylic / 2.5 mils silicone), carrier (4oz non-woven nylon), compliance requirements, and finished format.
