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.
Ang mga operator ay dapat magsuot ng mga dust mask habang ginagamit upang maiwasan ang paglanghap ng alikabok, at mabawasan ang pangmatagalang pagkakadikit sa pagitan ng balat at powder coating. Maaaring hugasan ng sabon ang pintura na nakakabit sa balat.
| Tukoy na gravity | 1.4~1.8g/cm' (depende sa formula at kulay) |
| maliit na butil laki | Depende sa layunin, ang karaniwang uri ay may average na laki ng butil na 35~40 microns, mas mababa sa 10 microns ng powder <10%, higit sa 100 microns ng powder <0.5%. |
| Katatagan ng imbakan | 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. |
