Product Overview
High and Low Temperature Resistance Butyl Hot Melt Sealant is a premium-grade, non-curing sealant designed to perform consistently in extreme temperature environments. It is formulated with high-quality butyl rubber and thermoplastic materials, giving it excellent flexibility, superior weather resistance, and outstanding adhesion to a wide range of substrates.
This sealant is specially engineered to maintain elasticity and sealing properties from frigid -40°C to scorching +120°C, making it suitable for both high-heat industrial environments and sub-zero climate applications. It provides an instant, durable bond when applied in molten form and remains permanently flexible, ensuring long-term protection against air, dust, moisture, and vibration.
Key Features
Extreme Temperature Tolerance: Performs reliably between -40°C and +120°C without cracking, melting, or losing adhesion.
Strong Initial Tack: Bonds immediately upon application, speeding up installation and minimizing labor time.
Non-Curing & Repositionable: Remains soft and pliable over time, allowing for easy repositioning and reapplication when necessary.
Waterproof & Airtight: Provides long-lasting sealing performance against water, air, and dust penetration.
Chemical and UV Resistance: Withstands degradation from sun exposure, industrial gases, and harsh weather.
Excellent Compatibility: Adheres well to metal, plastic, wood, concrete, glass, and composite materials.
Solvent-Free and Low VOC: Safe for use in enclosed environments and environmentally compliant.
Typical Applications
Cold Storage Rooms & Freezers: Ideal for sealing joints in walk-in coolers or refrigerated spaces where low-temperature flexibility is essential.
Solar Panels & Rooftop Installations: Used for waterproofing and bonding in high-temperature, UV-exposed environments.
Automotive Assembly: Applied in areas subject to thermal cycling and vibration such as window frames, door panels, and lights.
HVAC Systems: Seals ducts and joints that undergo significant temperature fluctuations.
Metal Roofing & Facade Systems: Fills gaps and joints in structures exposed to both hot sun and cold weather.
Electrical Cabinets & Outdoor Enclosures: Provides weatherproof sealing in sensitive equipment housings.

FAQ (Frequently Asked Questions)
Q1: What makes this sealant suitable for extreme temperatures?
A1: It is specially formulated with advanced butyl rubber and stabilizers that allow it to remain flexible and effective in both very low (-40°C) and high (+120°C) temperatures without degrading.
Q2: Can it be used in direct sunlight or outdoors?
A2: Yes. It has excellent UV and weather resistance, making it suitable for long-term outdoor use, including roofing and solar installations.
Q3: Does it require curing time after application?
A3: No. It bonds immediately upon application and cools quickly without the need for curing, improving work efficiency.
Q4: Is it safe for use indoors or in food storage areas?
A4: Yes. It is solvent-free, non-toxic, and low in VOC, making it safe for indoor environments, including cold storage and food-related facilities.
Q5: What materials can it bond to?
A5: This sealant adheres strongly to aluminum, stainless steel, glass, PVC, wood, concrete, and most construction composites.
Q6: How do I clean excess material?
A6: While still warm, it can be removed using a clean cloth. Once cooled, it can be peeled off or cleaned with mineral oil or mild solvents.
Q7: Is it compatible with painted or coated surfaces?
A7: Yes, but we recommend testing a small area first to ensure compatibility, especially on specialty coatings or paints.
