Product Categories
Polyurethane Adhesives
Two-component and medium-hardness polyurethane systems for air, diesel, hydraulic, gearbox, cement-plant, and steel-plant filtration applications.
Filter Paper Adhesive
A one-component adhesive designed for butt bonding filter papers, suitable for manual or machine application.
Epoxy Encapsulation Adhesive
Adhesive systems for electronic component encapsulation and sensor-coil filling. Curing and resistance requirements should be matched to the application.
Acrylate Structural Adhesives
Two-component reactive systems, including 10:1 and 1:1 products, designed for broad material compatibility and high-strength bonding.
Hot-Melt Adhesives
Products designed for oil, heat, and moisture resistance, with a fast initial set suited to efficient production.
Sealants and Thread-Locking Products
Products for threaded-cover sealing and related applications. Available performance varies by grade and may include resistance to oil, solvents, temperature, aging, shock, and impulse testing.
Filter Film
Environmentally focused filter films for air, diesel, fuel, and oil-filter applications.
Representative Technical Data
Hot-melt adhesive: white particle appearance, softening point of 140-150 deg C, dissolution viscosity of 10000-15000 cps at 230 deg C, density of 1.28 g/cc, 100% solid content.
MS adhesive: black appearance, 100% solid content, moisture curing, 6-20 minute dry time, application temperature 5-40 deg C, service temperature -40 to 100 deg C.
The current technical data sheet for the recommended grade is supplied with every recommendation, so your engineers can verify performance before a trial.
Selecting the Right Adhesive
The right adhesive depends on the substrate, filter type, operating temperature, chemical exposure, curing process, and production method. Send those details so the factory can recommend a grade and relevant tests.
Samples and Factory Visits
After reviewing the application, we can confirm whether a sample is available and arrange express delivery. Factory visits in Shanghai can be scheduled in advance.
