Product Description
Permabond A130 is a medium-strength anaerobic threadlocker with dual drinking water approval (KTW-BWGL + WRAS) — the right choice for sanitary and water treatment technology with the highest hygiene requirements.
With its thixotropic consistency (1,800 mPa·s @ 20 rpm, 8,000 mPa·s @ 2 rpm), A130 does not drip from vertical threads—the adhesive stays where it is applied. Threads up to M20 (¾") are reliably secured with gap filling up to 0.12 mm.
The breakaway torque of 12 N·m is in the medium-strength range — resistant to vibration, removable with standard tools. Dual drinking water approval (German KTW-BWGL and British WRAS) qualifies A130 for direct contact with drinking water according to both European standards — a rare feature for threadlockers.
KTW-BWGL + WRAS drinking water approval — dual certification for direct contact with drinking water according to German and British standards. Vibration-resistant, removable with standard tools, with thixotropic consistency for vertical applications.

Frequently asked questions about Permabond A130
Practical application and design questions — answered by SILITECH.
Permabond A130 is an anaerobic acrylic adhesive with a viscosity of 1,800 mPa·s @ 20 rpm / 8,000 mPa·s @ 2 rpm (thixotropic) and gap filling up to 0.12 mm. It is a medium-strength threadlocker with dual drinking water approval (KTW + WRAS). Anaerobic adhesives cure in the absence of air and in contact with metal — ideal for tight-tolerance metallic joints.
Anaerobic adhesives like Permabond A130 remain liquid in the bottle (due to contact with air and oxygen) and only begin to harden after bonding under anaerobic conditions and metal-to-metal contact. Curing starts at the metal surface and progresses into the bond gap. The product cures quickly on steel and copper; on stainless steel and zinc, the Permabond A905 activator may be beneficial.
Yes, with tools — Permabond A130 is medium-strength (12 N·m breakaway torque) and can be loosened with standard tools. If necessary, the bond can be gently heated to facilitate disassembly.
Permabond A130 is approved according to KTW-BWGL Drinking Water Approval and WRAS Drinking Water Approval . These certifications qualify the product for the respective specified applications—such as direct contact with drinking water in the case of WRAS and KTW approvals.
Permabond A130 typically reaches handling strength after 15 minutes and functional strength after 1 hour at 23 °C on M10 steel. Final strength is reached after 24 hours. On inactive surfaces (stainless steel, zinc) or at low temperatures, the curing time is extended—Permabond A905 activator accelerates the process.
Permabond A130 is a medium-strength threadlocker suitable for drinking water (1,800 mPa·s @ 20 rpm / 8,000 mPa·s @ 2 rpm (thixotropic) viscosity, 0.12 mm gap filling, 12 N·m breakaway torque). Permabond A113 is a medium-strength threadlocker (500 mPa·s, 0.12 mm gap filling, 12 N·m breakaway torque) — low viscosity, WRAS. Both belong to the anaerobic Permabond A series.
The choice depends on the application: Permabond A130 (medium-strength threadlocker, drinking water); Permabond A113 (medium-strength); Permabond A011 (low-strength); Permabond A025 (high-strength, high-temperature). For inactive surfaces (stainless steel, zinc, aluminum), Permabond A905 activator be used to accelerate curing.
