南非采购需求：防水防油整理剂、防污整理剂

I'm looking for a reliable sealer specifically designed for tarpaulin applications. It's crucial that the product offers strong adhesion and durability, as it will be used in various outdoor conditions. I'm also interested in understanding the application process, curing time, and any specific surface preparation required to ensure optimal performance. Additionally, could you provide details on the packaging options available, as well as the minimum order quantities and pricing? If there are different types or formulations of sealers that you offer, please include that info too. It's important for us to find a product that not only meets our technical requirements but also offers good value for our budget. Looking forward to your prompt response!
