Product Features:
Fluorescent Brightener OB-1 is a complex organic compound. Its characteristic is that it can stimulate the incident light to produce fluorescence, so that the dyed substance can obtain a fluorescent effect similar to that of fluorite, and the substance seen by the naked eye is very white, to achieve whitening effect. In daily life, there are many opportunities for exposure to fluorescent agents.

Applications:
Fluorescent Brightener OB-1 is mainly used in textiles, papermaking, plastics, coatings, detergents, printing ink, wax, packaging materials, etc. It is only optical brightening and color supplement, and can not replace chemical bleaching. Therefore, the whitening effect can not be obtained fundamentally without bleaching and directly treated with whitening agent.
Packing and Storage:
15kg/Bottle, or 5kg*4 Carton, or 5kg*2 Cartion.
No decomposition at room temperature, but should be stored in a cool and dry place. Keep away from hot, fire source, avoid direct sunlight. Recommended storage and mixing areas have good ventilation conditions to avoid inhalation. Transportation according to the general chemicals.
The dose description:
Add the amount of fluorescent whitening agent ob-1 per 100kg of polymer (reference amount)
Transparent: The amount added is 0.0025-0.005% (2.5g-5g)
The general dosage is: 0.0025-0.025% (2.5g-25g) Not more than 0.03% (30g)
When adding any UV absorber to the polymer, care should be taken to adjust the optimum amount of the optical brightener OB-1.
