Foam Polyurethane 840

Polyurethane
 GMAX Polyurethane Spray Foam is a leading insulation solution, originally developed in the 1940s for military aircraft applications and becoming widely used for general insulation in the 1970s. GMAX Polyurethane Foam is ideal for object insulation, composed of two key liquid components—polyol and isocyanate—that react when mixed, expanding into foam and solidifying quickly. This rapid drying process ensures a durable, long-lasting insulation that resists cracking or deformation. GMAX foam is easy to trim to the desired size if it extends beyond the application area, providing an efficient and permanent insulation solution for various applications.

product usage

GMAX Polyurethane Foam offers versatile applications for both insulation and sealing:

  • Sound insulation for engines, vehicles, and partition walls, reducing noise and improving comfort.
  • Sealing between wooden panels, ensuring a secure and tight fit.
  • Filling seams, cavities, cracks, and fractures around water and electrical systems, preventing leaks and energy loss.
  • Thermal insulation for sewer pipes, water pipes, and central heating systems, enhancing energy efficiency and reducing heat loss.
  • Sealing between wooden doors and windows, as well as PVC, ensuring airtight protection and improved insulation.
  • Insulation of wall panels, prefabricated walls, and ceiling panels, offering superior temperature regulation and soundproofing.

GMAX Polyurethane Foam provides a durable, long-lasting solution for a wide range of sealing and insulation needs, improving efficiency and comfort in various applications.

how to maintain

 When using GMAX Polyurethane Foam, always wear a mask, goggles, protective clothing, and safety gloves. Avoid inhaling the vapors of the foam. In case of eye contact, rinse immediately with plenty of water and seek medical attention without delay.

Store the foam in a cool, dry place, away from direct sunlight, and ensure the temperature does not exceed 50°C. Never pierce or burn foam cans after use. Keep the product out of reach of children for safety.

How to use

 For optimal results when using GMAX Polyurethane Foam Sealant, follow these steps:

  1. Clean the Surface: Before applying the adhesive or sealant, ensure the surface is free of grease and dust. This will enhance the bonding quality and improve the strength and durability of the seal.

  2. Prepare the Foam: Shake the polyurethane sealant spray foam for 1 minute or 20 times to ensure the contents are well-mixed. This step is crucial for maximizing the foam’s quality and efficiency.

  3. Moisten the Surface: Lightly spray the surface with water to increase moisture levels. This helps the polyurethane foam adhere better, boosting its performance and efficiency.

  4. Spray Slowly and Evenly: Apply the foam at a slow and consistent speed. Avoid spraying too quickly, as this ensures the polyurethane and gas inside the foam mix in the correct ratio for optimal results.

  5. Allow to Dry: Let the foam dry completely. Once dried, use a cutter to trim any excess foam to the desired level, achieving a neat finish.

  6. Finishing Touches: The dried foam can be sanded or painted to your preference for a smooth, polished look.

By following these steps, you ensure the highest quality, efficiency, and durability when using GMAX Polyurethane Foam for sealing and insulation projects.
