Frequently Asked Questions
Q
What surfaces is this product compatible with?This product is suitable for PVC, silicon PU, polyurea and other base surfaces, providing excellent strength and adhesion across a variety of substrates.
Q
What is the correct mixing ratio for this two-component coating?The mixing ratio by weight is Component A (main agent) to Component B (curing agent) at 15:1. Allow 5 minutes of mixing before beginning construction.
Q
How long does it take for the coating to fully dry?The surface drying time is approximately 2 hours. Full (real) drying is achieved within 24 hours under normal conditions.
Q
What are the recommended construction temperature and humidity conditions?The coating should be applied at temperatures between 5–35℃ and relative humidity below 80%. Avoid construction when the substrate surface temperature exceeds 40℃ or during rain, snow, wind, or sandstorm conditions.
Q
How should this product be stored, and what is its shelf life?Store in a cool, dry, and well-ventilated indoor warehouse away from all fire sources. The shelf life is half a year (6 months) from the date of manufacture.
Q
What safety precautions should be followed during application?All fire sources must be prohibited at the construction site. Workers must wear appropriate protective equipment to prevent inhalation of paint mist and contact with eyes and skin. If contact occurs, wash skin with soapy water immediately and flush eyes with large amounts of water, then seek medical attention.
