Product Description
Permabond MH196 is an anaerobic gasket maker in paste form — designed to form formed-in-situ gaskets between metallic flanges, as a replacement for classic paper, cork or rubber gaskets.
Unlike conventional threadlockers or shaft-hub adhesives, MH196 is a pure surface sealant—it is applied to one of the flange sealing surfaces and, when the components are joined, forms a custom-fit seal within the gap geometry. The paste consistency (500,000 mPa·s) remains precisely where it is applied.
MH196 replaces pre-cut flat gaskets made of paper, cork or rubber — with the advantages: no need to stock different gasket shapes, no wear and tear as with rubber gaskets, no creep, full-surface pressure distribution and corrosion protection on the flange contact surfaces.
Anaerobic gasketmaker — formed-in-situ surface gasket — Permabond MH196 replaces conventional flat gaskets made of paper, cork, or rubber. When the flanges are joined, the gasket forms a precise fit within the gap geometry, thus preventing the wear and creep of conventional gaskets.

Frequently asked questions about Permabond MH196
Practical application and design questions — answered by SILITECH.
Permabond MH196 is an anaerobic acrylic sealant with a viscosity of 500,000 mPa·s @ 2 rpm (paste) and a gap-filling capacity of up to 0.5 mm. It is an anaerobic surface gasket—formed-in-situ gaskets between metallic flanges—replacing conventional flat gaskets. Anaerobic adhesives cure in the absence of air and in contact with metal—ideal for tight-tolerance metallic joints.
Anaerobic adhesives like Permabond MH196 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.
Mechanical separation — surface seals are separated by lifting or sliding the components sideways. Slight heating can facilitate separation.
Permabond MH196 does not have specific industry approvals such as WRAS or KTW (drinking water). For general industrial applications, the product is approved according to Permabond's internal specifications; product-specific testing prior to series production is recommended.
Permabond MH196 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 MH196 is an anaerobic gasket maker — formed-in-situ (500,000 mPa·s @ 2 rpm (paste) viscosity, 0.5 mm gap filling, 20 N·m breakaway torque). Permabond A136 is an acrylic gasket maker (paste, 0.5 mm, 10 N·m breakaway torque) — an acrylic gasket maker with WRAS. Both belong to the anaerobic Permabond A series.
The choice depends on the application: Permabond MH196 (anaerobic gasket sealant – formed-in-situ); Permabond A136 (acrylic gasket sealant); Permabond A129 (pipe sealant gel); Permabond A1058 (pipe sealant paste). For inactive surfaces (stainless steel, zinc, aluminum) Permabond A905 activator be used to accelerate curing.
