Sealant Manufacturers produce adhesive and sealant products that are used to bond materials together, including plastics. Some sealants are designed for specific purposes, such as sealing joints in concrete or preventing water intrusion into electrical equipment. Others are used in industrial settings and are formulated to withstand harsh conditions and heavy loads. The companies that make these products are a vital link in the chain of commercial manufacturing, and they serve industries as diverse as automotive, aerospace, electronics and metallurgy.
Typically, modern sealants are formulated from synthetic elastomeric polymers that provide flexibility and can bridge gaps. They may also contain fillers that help them adhere to materials. Some manufacturers of these products provide a range of formulas to accommodate different needs, with the final choice resting with the end user. If long-term performance and weatherability are a concern, the user can inquire about results from accelerated testing performed on the sealant.
Some of these tests can include a test that evaluates the material’s ability to resist chemical attack, as well as how it performs under different temperatures and exposure to sunlight. Another test that is often performed involves measuring the rate of shrinkage of the sealant when it is cured. This can be an important factor when choosing a product, as excessive shrinkage can result in internal stresses within the joint.
Many sealant manufacturers also sell the tools and accessories that are needed for applying the products, such as mixing containers, PVC made cartridges, nozzles and guns. A gun allows the sealant to be applied quickly, and it can also be used for mixing the base and accelerator of two-part systems. Spatulas are an alternative tool for applying sealants, and they can be used for small projects when the application is straightforward.
In addition to the tools, manufacturers of these products often offer a selection of materials and additives for use with their product lines. Some of these materials are made from renewable resources, such as silicones. For example, the German company WACKER SILICONES offers a line of green silicone sealants that are based on methanol from renewable raw materials. The Munich-based company also makes a variety of other types of silicones for use in the construction industry.
Some manufacturers of sealants and adhesives are members of the Sealant Engineering and Associated Lines (SEAL). SEAL is a not-for-profit trade organization that provides education on the design, distribution and manufacture of adhesive and sealant products. In addition to offering educational programs, SEAL provides a forum for companies in the industry to share ideas and best practices. These organizations can be an excellent source of information for businesses looking to improve the efficiency of their operations and reduce waste in the production process. In addition, they can offer valuable sales leads for companies that are looking to expand their market presence in the global marketplace.
