Powder Coatings vs. SPI Coating Products

Coatings from Superior Products International II, Inc. provide long-term solutions to previously unsolvable problems. We pride ourselves on developing durable, versatile coatings that outperform the competition. What makes our coatings better? Read for yourself:

  • Resin Types

    The SPI insulation, fire and base coatings are water-based. The corrosion coatings are solvent-based for penetration and durability. The goal is to look at how the surface will be used and then come up with the appropriate coating formula and strength to match the need.

  • Surface Preparation

    The SPI coatings can be applied to any surface that is clean of dirt, grease, and dust. They can even be applied over existing coatings as long as they are not flaking or loose. Rust GripĀ® can be coated directly over surface rust and corrosion to seal the surface and is patented to encapsulate asbestos and lead based paints. If any existing coating has a gloss surface, the gloss must be sanded or light-blasted to remove the sheen. The coating does not have to be removed, just the gloss.

  • Application

    The SPI coatings were developed for easy application with a brush, roller, air-assisted sprayer, or airless sprayer. This allows for on location application on parts of any size and shape. The SPI coatings require dry and cure time for optimal performance.

  • Clean Up

    Overspray is always a concern with liquid applied coatings. Although the material cannot be recovered, proper masking of work area will limit the chance of applying the product to unintended surfaces. Clean up for our water-based products is simple, with soap and water being more than sufficient. The solvent-based products require MEK or xylene to remove.

  • Durability and Longevity

    The SPI coatings carry some of the longest-lasting liquid applied systems available. Super Therm® has an expected lifespan in excess of 15 years, and Rust Grip® sets to a 6700 psi surface tensile strength after 3 weeks and gives additional strength and durability to any surface it covers.

  • Environmental

    Our water-based products are environmentally friendly and do not release solvent emissions. Our solvent-based coatings are formulated to meet environmentally green standards. The SPI Coatings have been certified environmentally safe and eco-effective by MBDC LLC (Gold Certificate) and are approved by the USDA approved for use in and around food preparation areas.
