STWD9539 is a single component aliphatic polyurea waterproof anti-corrosion coating material, which has excellent adhesion to various substrates. Due to the unique chemical structure of aliphatic prepolymers, this product not only has excellent high elasticity, high strength, wear resistance, and impact resistance, but also has excellent corrosion and weather resistance. It does not pulverize or change color when used outdoors for a long time, and has good decorative effects.
❓Frequently Asked Questions
Q1: Can STWD9539 be used in extremely cold or hot climates?
A1: Yes, the cured coating maintains its performance in environments ranging from -50 ºC to 80 ºC, making it suitable for global use.
Q2: Does this product require mixing with other chemicals?
A2: No, it is a single-component aliphatic polyurea, meaning it is ready for use without the need for complex mixing, which reduces error and labor costs.
Q3: What is the main advantage of "Aliphatic" polyurea over standard types?
A3: Aliphatic polyurea is UV-stable. Unlike standard versions, it will not yellow, pulverize, or lose color when exposed to direct sunlight for long periods.
Q4: How should the metal substrate be prepared?
A4: It is recommended to perform sandblasting to achieve the Sa2.5 level according to ISO8501-1 standards to ensure maximum adhesion.
Q5: What is the shelf life and storage requirement?
A5: The shelf life is 12 months when sealed. It should be stored in a cool, ventilated place (5ºC-32ºC) away from heat and direct sunshine.
Q6: Can I walk on the coating shortly after application?
A6: At a standard temperature of 20ºC, the surface allows foot traffic after 24 hours. Full solid dry takes approximately 6 days.
