Application Guidelines

Surface Preparation
Before applying PU761, ensure the substrate is free of grease, dust, moisture, and other contaminants, and pre-coated with the corresponding primer. To ensure film appearance, the primer should be smooth and free of surface defects such as dry spray and orange peel.
Mixing & Dilution
PU761 is a two-component product requiring precise component ratio. Thoroughly mix the entire contents of each paint bucket before use. First, stir the base material until uniformly smooth (no more than 2 minutes), then slowly add the curing agent and stir for 3 minutes. A variable-speed power stirrer is recommended. Avoid over-stirring, as this may accelerate curing and shorten the product’s pot life. High temperatures shorten the mixture’s working life, while low temperatures extend it. Dilution is generally unnecessary; if required, add a small amount of thinner (5% or less) in compliance with local VOC and air quality regulations.
Application
PU761 can be applied by airless spraying, roller coating, or conventional spraying.
Ventilation: Maintaining good ventilation in enclosed spaces is critical for applicator safety and product performance. The air must be dry, as application is not permitted at humidity >85%.
Recoat Interval
Refer to physical parameters under different ambient temperatures (details available in application guidelines).

Safety Measures

Warning: May cause eye and skin irritation. Vapors may trigger respiratory allergies in sensitive individuals. Possible skin allergic reactions. Avoid inhaling vapors. Keep away from eyes and skin. Wear protective equipment for eyes, ears, and skin. Use a suitable respirator to prevent potential respiratory irritation. Thoroughly wash skin after use. Launder clothing before reuse. In case of respiratory arrest, perform mouth-to-mouth resuscitation and seek immediate medical attention.
First Aid: In case of eye contact, flush with clean water for at least 15 minutes and remove contaminated clothing/footwear. Wash skin with soap after contact.
