Tengyu Chemical’s Ventilation Duct Sealant is primarily used for sealing HVAC systems, suitable for sealing common joints in duct installations and system installations. The products are currently divided into two categories: water-based pipe sealants, suitable for sealing joints in HVAC duct systems, offering low VOCs and superior bond strength; and fire-retardant sealants for applications requiring fire resistance ratings.
Water-Based HVAC Duct Sealant Solutions
TA102 Acrylic Latex Duct Sealant is a water-based, high-performance duct sealing compound designed for HVAC duct systems operating under medium to high pressure conditions. It provides permanent flexibility and reliable adhesion for long-term airtight sealing in professional ventilation installations.
Formulated for HVAC contractors and system installers, TA102 Ventilation Duct Sealant delivers strong sealing performance across metal ducts, duct board, and flexible duct systems, ensuring stable performance in demanding environments.
- Excellent for HVAC Duct Sealing Applications
- Permanent Flexibility for Long-Term Performance
- Excellent Water Resistance
- Low VOC & Low Odor
- Non-Corrosive to Metals
- High Solid Content & Slump Resistant
Typical Applications
- HVAC sheet metal duct systems
- Duct board and flexible duct installations

- Air leakage control in ventilation systems
Fire Rated HVAC & Construction Sealants Solutions
TA103 Firestop Acrylic Sealant is a single-component, non-sag fire-resistant acrylic sealant designed for sealing low-movement interior joints in construction applications. It forms a reliable fire barrier in masonry and plasterboard systems, providing fire protection performance for up to 4 hours under specified conditions.
Formulated for professional building applications, TA103 fire rated mastic sealant offers strong adhesion to common construction substrates and is suitable for fire-rated joint sealing in walls, penetrations, and service installations.
- Excellent for Fire-Rated Joint Sealing Applications
- Up to 4 Hours Fire Resistance (in specific systems)
- Good Adhesion to Common Construction Materials
- Non-Sag & Easy Application
- Paintable with Water-Based Paints
- Low Movement Joint Compatibility
Typical Applications
- Construction and expansion joints
- Metal pipes and conduits
- Cable bundle penetrations
- HVAC system penetrations
Intumescent Fire Rated Acrylic Sealant Solutions
TA104 Intumescent Fire Rated Acrylic Sealant is a one-component, ready-to-use fire-resistant sealant designed for ductwork and a wide range of fire-rated construction joint applications. It is used to maintain fire integrity in compartment walls, floors, and service penetration areas where fire and smoke resistance are required.
When exposed to heat, TA104 fire rated joint sealant expands to form a stable intumescent char layer, helping to block the spread of fire and smoke while maintaining the integrity of building structures.
- Excellent for Fire-Rated Construction and Penetration Sealing
- Intumescent Expansion Under Heat Conditions
- Up to 4 Hours Fire Resistance (in specific systems)
- Maintains Integrity, Stability, and Insulation
- Excellent Adhesion to Common Building Substrates
- Ready-to-Use, Easy Application
Typical Applications
- HVAC ductwork fire sealing
- Fire-rated expansion joints
- Metal pipes and conduit
- Cable bundle sealing
- Fire-rated doors and partition assemblies
- Wall and floor service penetrations
Acrylic emulsion duct sealant is primarily used for sealing joints in HVAC duct systems, effectively reducing air leakage and ensuring system airtightness and operational stability.
In actual construction, HVAC contractors typically use it for duct splicing, joint sealing, and localized repairs. It is easy to apply and suitable for routine duct installation and maintenance.
If you are working on a duct installation or system maintenance project, you can select the appropriate model based on your specific working conditions. We can also provide matching product recommendations and technical support solutions for different regions or project requirements.
