黎巴嫩采购需求：抗紫外线、聚氨酯胶、聚氨酯泡沫、密封胶、聚氨酯喷雾、管道

I'm looking for detailed information regarding your PU waterproofing product. Could you clarify whether the formulation is based on xylene or water? Additionally, I would appreciate it if you could provide insight on the coverage; specifically, how many square meters can be covered with a 25-liter container? Furthermore, I would like to know the pricing for this quantity. If there are any bulk purchase options or discounts available, please include that information as well. Your prompt response would be greatly appreciated, as I am eager to evaluate this product for my upcoming projects. Thanks!
