FAQ's of Interthane 990:

Q: How should Interthane 990 be mixed before application?

A: Interthane 990 requires a 4:1 volumetric mixing ratio of base to hardener. Thoroughly mix the components to ensure a homogeneous mixture before applying with brush, roller, or airless spray. Consult the technical data sheet for detailed mixing instructions.

Q: What substrates are compatible with Interthane 990 and how should they be prepared?

A: Interthane 990 is suitable for primed steel, concrete, GRP, and aluminum surfaces. Ensure surfaces are properly cleaned, free of contaminants, and primed with a compatible primer prior to application for optimal adhesion and performance.

Q: When is it safe to recoat Interthane 990, and what is the recommended recoating interval?

A: The minimum recoating interval for Interthane 990 is 16 hours at 25C. Ensure the surface is free of grease, dust, or other contaminants before applying additional coats for best results.

Q: Where is Interthane 990 typically used?

A: This polyurethane topcoat is used in industrial environments, including protective and decorative coatings for steel structures, machinery, aluminum, concrete, and GRP surfaces in aggressive outdoor or indoor conditions.

Q: What are the key benefits of using Interthane 990 in industrial applications?

A: Key benefits include excellent weather and UV resistance, high mechanical and abrasion strength, long-lasting gloss retention, and suitability for use in harsh industrial settings requiring durability and aesthetic appeal.

Q: What is the recommended film thickness and how much area does Interthane 990 cover?

A: A dry film thickness of 50-75 microns is recommended per coat. At 50 microns DFT, Interthane 990 offers a theoretical coverage of 8-10 m2 per liter, supporting efficient material usage on large projects.

Q: How should Interthane 990 be stored to maintain its quality?

A: Store the product in a cool, dry place away from direct sunlight in tightly sealed metal cans. Under ideal storage conditions, Interthane 990 has a shelf life of 24 months.
