KASTAR says it will present its in-house silane-terminated polymer synthesis technology at The Big 5 Global 2026 in Dubai, running November 23–26 at Dubai World Trade Centre. The company is highlighting two MS polymer sealants: MS971 Multi-purpose MS Polymer Sealant for broad building-sealing work, and MS973 Fast Dry MS Polymer Sealant for sheet-metal, HVAC and vibration-prone applications. Distributors, importers, building-material brands and project buyers can also discuss OEM and ODM supply options. Booth information conflicts across KASTAR’s own pages, so visitors should confirm the final location before traveling.
What is KASTAR showing at The Big 5 Global 2026?
KASTAR’s exhibition focus is its in-house silane-terminated polymer synthesis technology and the MS polymer sealants developed with it. The company says the technology is designed to support adhesion, flexibility, weather resistance, low volatile-organic-compound emissions, ultraviolet resistance and compatibility with water-based paints. Those are company-reported characteristics; the technical data sheet for the exact formulation remains the document to use for a project specification.

What are KASTAR MS971 and MS973 used for?
MS971 and MS973 serve different project needs. MS971 is the general-purpose option described for perimeter sealing and a range of construction joints, while MS973 is positioned around faster drying and flexible bonding in fabrication and services work.

Is MS polymer sealant suitable for outdoor construction?
KASTAR presents its MS polymer technology as supporting weather resistance and UV resistance, and MS971 is aimed at roofing, gutters, perimeter sealing and exterior construction joints. Whether a particular joint is suitable depends on the formulation, substrate preparation, movement requirement, exposure and local code; obtain the product’s current technical data sheet before approving it for an outdoor detail. Compatibility with water-based paints is a company claim that should likewise be checked for the specific grade and paint system.

The company says it wants meetings with international distributors, building-material brands, importers, wholesalers and project buyers. Its OEM/ODM offer can be discussed around formulation, color, viscosity, packaging and private-label requirements.
For a productive meeting, buyers should bring the substrates, joint or bonding use, expected movement, climate exposure, packaging format, annual volume and destination-market requirements. Ask for the relevant technical data sheet, safety documentation, curing conditions, shelf life, color options and confirmation that the proposed packaging and labeling meet the importing country’s rules.

What scale does KASTAR report?
In its October 2026 announcement, KASTAR reports the following company figures:
- 28 years of adhesive and sealant manufacturing experience.
- 28 R&D engineers and 35 patents.
- Approximately 150,000 square meters of facilities across five Chinese provinces.
- 600,000 metric tons of annual production capacity across its portfolio, including 300,000 metric tons of sealants.
- More than 1,000 customers and exports to 69 countries and regions.
- A testing center exceeding 1,000 square meters, with 12 inspection stages.
KASTAR also reports an outgoing defect rate of no more than 0.03 percent. That figure is a company quality-control claim; the announcement says its measurement period and calculation method can be confirmed on request, so it should not be treated as an independently verified industry benchmark.

How should visitors verify the booth and prepare for Big 5 Dubai?
- Check the official The Big 5 Global exhibitor information shortly before the event.
- Ask KASTAR to confirm whether the final assignment is 8E 331A in Za’abeel Hall 3 or 6F 260.
- Request the current MS971 or MS973 technical data sheet for the destination country and intended application.
- Bring a written project brief covering substrates, joint dimensions, movement, cure-speed needs, color, packaging and estimated volume.
- For private-label or OEM discussions, clarify formulation ownership, incoming inspection, labeling, documentation and minimum order requirements before requesting a quotation.
What should buyers verify before specifying either product?
The announcement establishes the products’ intended roles but not a full side-by-side set of tensile, elongation, hardness, skin-formation, cure-rate, service-temperature or storage figures. Those values can vary by formulation and market. A buyer should therefore base approval on the applicable technical and safety documentation, a substrate-compatibility check and the project’s installation conditions rather than on the technology-level claims alone.
Frequently asked questions
Are MS971 and MS973 sold in every export market?
That is not established by the announcement. Availability, labeling and documentation can differ by destination, so an importer should ask KASTAR to confirm the exact grade, packaging and compliance documents for the receiving country.
