This series of products is made of saturated polyester resin and isocyanate curing agent as the main base material.
Suitable for coating of various products exposed outdoors for a long time: such as household appliances, architectural aluminum profiles, transportation facilities, stadium facilities, courtyard facilities, etc.
Carton packaging, lined with two layers of polyvinyl chloride plastic bags, net weight of 20kg per box. Non-hazardous items can be transported in various ways, but should be kept away from direct sunlight, moisture and heat, and contact with chemicals.
Operatører bør bære støvmasker under brug for at undgå indånding af støv og minimere langvarig kontakt mellem hud og pulverlakering. Maling, der sidder fast på huden, kan vaskes med sæbe.
| massefylde | 1.4~1.8 g/cm' (afhængigt af formel og farve) |
| Partikelstørrelse | Afhængigt af formålet har standardtypen en gennemsnitlig partikelstørrelse på 35~40 mikron, mindre end 10 mikron pulver <10%, mere end 100 mikron pulver <0.5%. |
| Opbevaringsstabilitet | Polyurethane powder coatings should be stored in a dry, ventilated room below 30°C, and avoid direct sunlight. If stored in an air-conditioned room, the powder must not be stored at room temperature or the same (temperature) as the spraying equipment before use to avoid moisture. Under this condition, the powder can be stably stored for more than 12 months. If it is exceeded, it must be re-tested. If the result meets the requirements, it can still be used. |
