What is Gasket Shellac
Gasket shellac is a hard-setting, resin-based liquid sealant used to coat, seal, and bond gaskets, threaded connections, hose fittings, and jointing surfaces in engines, fuel systems, carburettors, and a wide range of industrial assemblies. It is one of the oldest and most trusted sealing compounds in the automotive and mechanical maintenance industry — valued for its exceptional resistance to engine oils, fuels, diesel, water, steam, antifreeze, and most common automotive and industrial fluids.
Gasket shellac is applied as a thin, even liquid coat to both mating surfaces of a gasket joint. As the alcohol-based solvent carrier evaporates, the compound hardens into a dense, flexible resin film that fills microscopic surface irregularities, bridges surface imperfections, and forms a reliable leak-proof seal between mating gasket surfaces — preventing oil seepage, fuel leaks, and coolant loss at low-pressure and low-temperature engine joints.
Unlike modern silicone gasket makers, gasket shellac is specifically designed for use with pre-cut gaskets — paper, cork, felt, cardboard, fibre, rubber, and composition type gaskets — where a traditional sealing compound is preferred over in-situ formed gaskets. Its simplicity of application, long shelf life, and compatibility with virtually all common gasket materials make it a perennial staple product in the automotive aftermarket, spare parts trade, and general mechanical workshop environment globally.

Exsan Gasket Shellac Product Range
As a specialist gasket shellac manufacturer, Exsan produces three distinct gasket shellac compound formulations — each targeted at specific performance requirements and market segments.
Heavy Duty Gasket Shellac
Exsan’s highest-performance gasket shellac formulation, engineered for demanding automotive and industrial sealing applications where maximum oil resistance, fuel resistance, and temperature tolerance are required. Heavy Duty Gasket Shellac forms an exceptionally hard, dense resin seal that withstands sustained exposure to engine oil, diesel fuel, petrol, coolant, water, and steam — making it the preferred choice for engine overhaul workshops, heavy commercial vehicle maintenance, and industrial equipment servicing environments.
Suitable for sealing paper, cork, fibre, rubber, and composition gaskets across engine oil pans, valve covers, timing covers, fuel pump assemblies, carburettor bases, and manifold joints in both petrol and diesel engines.
Honey Gasket Shellac
A smooth, slow-setting gasket shellac formulation with a characteristic amber honey colour and viscosity — designed for general automotive sealing applications where ease of application and consistent film formation are the priority. Honey Gasket Shellac flows easily into surface irregularities and sets to a hard, resilient film that bonds reliably with paper, cardboard, felt, and composition gasket materials across a wide range of low-pressure engine and fuel system joints.
Particularly popular in the automotive spare parts and accessories retail trade as a universal workshop sealing compound — its familiar amber appearance and easy-pour viscosity make it a preferred choice for mechanics and service technicians across all markets.
True Glue Gasket Shellac
A stronger-bonding gasket shellac compound formulated for applications where additional adhesive strength is required in addition to sealing performance. True Glue Gasket Shellac bonds pre-cut gaskets firmly to mating surfaces before assembly — preventing gasket movement during installation and maintaining seal integrity under thermal cycling and vibration in assembled engines and mechanical systems.
Ideal for applications where gasket retention is critical during assembly — including multi-piece gasket sets, thin paper gaskets on fuel system components, and joints subject to vibration in commercial vehicle and agricultural equipment engines.
Technical Properties of Exsan Gasket Shellac
Chemical Type
Rosin and natural resin-based formulation in an alcohol solvent carrier — the same proven chemistry that has been the industry standard for gasket shellac compounds for over a century.
Appearance
Dark brown to amber viscous liquid with a characteristic resin odour — consistent with standard gasket shellac classification.
Temperature Range
Effective from −54°C to +177°C (−65°F to +350°F) — covering the full operating temperature range of standard automotive engine joints and fuel system components.
Fluid Resistance
Resistant to engine oil, diesel fuel, petrol, water, steam, coolant, antifreeze, and most common automotive and industrial workshop fluids.
Compatible Gasket Materials
Paper, cork, felt, cardboard, fibre, rubber, and composition type gaskets — compatible with virtually all pre-cut gasket materials used in automotive and industrial assembly.
Application Method
Applied by brush, swab, or direct pour to both mating surfaces in a thin, even coat. Allow to become tacky before assembly. Full cure achieved after assembly under normal operating temperatures.
Cleanup
Easily cleaned with alcohol, acetone, or chlorinated hydrocarbons before cure — no specialist tools or solvents required.
Applications for Exsan Gasket Shellac
Automotive Engine Assembly and Overhaul
The primary application for gasket shellac across all global markets — used extensively in engine rebuilding, cylinder head gasket sealing, oil pan gasket assembly, valve cover gasket fitting, and timing cover sealing in both petrol and diesel engines across passenger cars, commercial vehicles, motorcycles, and agricultural equipment.
Fuel System and Carburettor Sealing
Gasket shellac is the traditional compound for sealing carburettor base gaskets, fuel pump flange gaskets, and fuel line threaded connections — providing reliable resistance to petrol, diesel, and ethanol-blended fuels in low-pressure fuel circuit joints.
Hose Connections and Threaded Fittings
Applied to threaded pipe connections, hose barb fittings, and hydraulic line connections in automotive, marine, and industrial assemblies to provide additional sealing backup and prevent seepage at threaded joints.
Marine and Industrial Machinery
Gasket shellac’s resistance to water, steam, and industrial fluids makes it a widely used sealing compound in marine engine servicing, industrial pump assembly, compressor maintenance, and general mechanical equipment overhaul applications.
Agricultural and Off-Road Equipment
Widely used in tractor, harvester, and construction equipment maintenance — where traditional gasket materials and shellac sealing compounds remain the standard approach for field repairs and scheduled maintenance in developing markets globally.
