180 Butyl Hot Melt Sealant And 190 Butyl Hot Melt Sealant

180 & 190 Butyl Hot Melt Sealant – High-Performance Butyl Adhesives for Industrial Sealing Applications

Product Description:

The 180 Butyl Hot Melt Sealant and 190 Butyl Hot Melt Sealant are premium-grade, rubber-based hot melt adhesives formulated for demanding industrial sealing applications. Engineered with high-purity butyl rubber, both grades offer excellent adhesion, superior sealing performance, and long-term durability in various environmental conditions. Whether used in insulating glass production, construction joints, electrical enclosures, or automotive applications, these sealants provide outstanding resistance to moisture, UV, temperature fluctuations, and chemical exposure.

The 180 series features a medium-soft texture, ideal for applications requiring high flexibility and adaptability to movement or vibration. It is especially suited for IG units (Insulating Glass), solar panel modules, and general-purpose sealing tasks.

The 190 series offers a slightly firmer consistency, delivering higher mechanical strength and superior gap-filling properties. It is frequently used in structural glazing, HVAC sealing, container sealing, and electronic component encapsulation where stronger bonding is needed.

Both grades are applied using standard hot melt dispensing equipment, ensuring easy and efficient installation with minimal waste. Once cooled, they form a non-hardening, durable seal that remains permanently flexible over time.

Product Feature And Application

FAQs (Frequently Asked Questions):

Q1: What is the main difference between 180 and 190 Butyl Hot Melt Sealants?

A1: The 180 series is softer and more flexible, ideal for applications requiring movement or vibration resistance. The 190 series is slightly firmer, providing stronger structural adhesion and better shape retention in more rigid applications.

Q2: Can I apply these sealants manually?

A2: These products are designed for use with hot melt applicators. Manual application is not recommended due to the high temperature and viscosity required for proper flow and bonding.

Q3: Are these butyl sealants weather-resistant?

A3: Yes. Both 180 and 190 series are highly resistant to UV, ozone, water, and temperature changes, making them suitable for indoor and outdoor applications.

Q4: Do these sealants harden over time?

A4: No. One of the advantages of butyl rubber is that it remains permanently flexible and does not harden or crack, even after prolonged exposure.

Q5: Are they suitable for glass-to-metal bonding?

A5: Absolutely. These sealants offer excellent adhesion to both glass and metal, making them ideal for insulating glass, construction, and electronics.

Q6: How should I store the product before use?

A6: Store in a cool, dry place at temperatures below 35°C. Keep the product in its original packaging to avoid contamination. Shelf life is typically 12 months.

Q7: Is it safe to use in environments with high humidity?

A7: Yes. Both sealant grades provide reliable moisture sealing and will not degrade in high humidity conditions.

Q8: Can I paint over these sealants after curing?

A8: These are non-curing hot melt butyl sealants. Painting over them is not recommended as paint may not adhere well to the non-hardening surface.
