Polyurethane

Spray Polyurethane Foam (SPF) is one of the most popular insulation materials available today. First developed in 1940 for military aircraft applications, SPF gained widespread use as an effective foam insulation material in the early 1970s. This innovative foam consists of two key liquid components: polyol and isocyanate. When mixed, these substances react and expand into a foam that solidifies quickly, creating durable and long-lasting insulation. The rapid drying process ensures that the foam maintains its shape and resists cracking over time. Any excess foam that extends beyond the application area can be easily trimmed to achieve a clean and precise finish. GMAX Polyurethane Foam is the ideal choice for permanent insulation solutions.

How to use

 Step-by-Step Guide for Using GMAX Polyurethane Sealant Spray Foam:
  1. Surface Preparation:

    • Ensure the surface is clean and free of grease, dust, and debris.
    • Proper surface preparation enhances the bond between the foam and the surface, resulting in stronger and more durable sealing.
  2. Shake the Spray Foam:

    • Before use, shake the polyurethane sealant spray foam vigorously for 1 minute or at least 20 times.
    • This step ensures the contents are thoroughly mixed, improving the foam’s quality and performance.
  3. Moisten the Surface:

    • Lightly spray water on the surface using a sprinkler.
    • Moistening the surface enhances adhesion and improves the efficiency of the polyurethane foam application.
  4. Apply the Foam:

    • Spray the foam at a slow and uniform speed.
    • Avoid spraying too quickly to ensure the polyurethane and gas mix in the correct ratio for optimal results.
  5. Drying:

    • Allow the foam to dry completely.
    • Once dried, trim any excess foam with a cutter to achieve the desired level and shape.
  6. Finishing:

    • The dried foam can be sanded or painted to achieve a smooth and polished finish.

By following these steps, you can ensure the best results when using GMAX Polyurethane Sealant Spray Foam for sealing and insulation projects.
