Sealants are a class of industrial adhesives that are used to create a tight bond between two components or to fill gaps in an assembled component. Sealants are available in liquid and paste form and can be applied to the mating surfaces before joining or sprayed directly into the gap between mated parts. Sealant manufacturers produce several varieties of products that offer different properties and may be categorized by the type of material used, cure method, application and appearance.
Most modern sealants are formulated from synthetic elastomeric polymers such as silicons, acrylics, butyl and chloroprenes. Like adhesive systems, sealant formulations are modified by various extenders and additives, including plasticizers, thixotropic agents, adhesion promoters and curing agents. External accessory materials such as primers, bond-breaker tapes and back up materials are also sometimes used in the application process.

Providing custom engineering adhesives and sealants for aerospace, automotive, military, industrial, electronic, medical and transportation applications. Products are available in a wide range of viscosities and meet a variety of performance, environmental and safety standards.
Thermoset sealants are used for bonding a wide variety of materials, including plastics, metals, composites and wood. They have the ability to withstand extreme temperatures, resist chemicals and provide superior water resistance. These advantages make thermoset sealants a popular choice for industrial applications.
Adhesives & sealants made with renewable and recycled ingredients are available from many companies. These green products are a cost-effective alternative to traditional solvent-based sealants and are often less harmful to the environment. They also help reduce long-term maintenance costs and increase the lifespan of equipment and structures.
Adhesive and sealant product companies focus on improving their products to ensure customer satisfaction. Some manufacturers also develop specialized solutions for difficult to bond materials. For example, RTV silicones can bond a variety of materials and are ideal for use in automotive and aerospace applications. Some companies also specialize in environmentally friendly products, including bio-based adhesives. Other manufacturers are focusing on reducing the amount of VOC emissions from their production plants to meet environmental regulations. This can help reduce the risk of dermatitis and other health problems caused by chemical exposure in the workplace. These changes are a result of increased demand for greener and more sustainable products. Many customers are switching to eco-friendly products from traditional solvent-based products. This trend is expected to continue into the foreseeable future. This means that adhesive and sealant product manufacturers will need to invest in more efficient processes to meet customer requirements.
