silicone masking stopper
No matter in what industry you work in, it might be crucial that you prevent contamination of different substances. If so, one of the things that you could choose to use is our silicone masking stopper. With our flexible and durable silicone masking stopper, you will be capable of creating a perfect air-tight seal, one that will allow you to make the entire process of masking jobs – such as spray painting and powder coating – easier and simpler. One of the most common questions our customer support team gets is whether or not one silicone masking stopper can be used for various containers and openings.
To answer this question right away, yes, you will be able to use our stopper for a wide range of openings in different shapes and sizes, mostly because it is quite soft and extremely flexible. Hence, you can make sure that you neatly seal all threads during the finishing process. It is important that we mentioned that various paints will not stick to the stoppers, which means that you will be capable of reusing them over and over again – which is something that can save your company a lot of money and resources over a specific period of time.
Some of the features and characteristics of our silicone masking stopper include that it is resistant to both low and high temperatures, it will prevent air, liquids, chemicals, acids, and light from entering the opening or container the stopper is placed on, and with it, you will not have to worry about the substance in the bottle changing its color, taste, or smell. Additionally, we offer these stoppers in a wide range of colors, shapes, and sizes, but if you cannot find a product that you are looking for, our customer support team will gladly walk you through the process of ordering a custom silicone masking stopper.
