Choosing a Silicone Sealant Supplier

Silicone sealants are very versatile and can be used to bind a variety of materials together. They are resistant to weathering, humidity, extreme temperatures and airborne pollutants.

They have a liquid, gel-like consistency when first applied and cure to a durable rubber-like texture over time. They are available in a wide range of colors and can be used for bonding, sealing, insulating, caulking and encapsulating applications.

High-performance sealants

High-performance sealants have a wide range of benefits that make them ideal for a variety of construction applications. Depending on the type of project, they can be used to adhere dissimilar materials, seal air leaks and bond to concrete, glass and metal. They are also able to withstand extreme temperatures and moisture, as well as absorb vibrations. These characteristics make them ideal for structural glazing applications, including skylights and façades.

The performance capabilities of a sealant depend on several factors, including adhesive strength and cohesive strength. Adhesive strength determines how much the sealant will be able to stretch and compress without breaking down. Cohesive strength refers to the ability of the sealant to hold substrates together during stress or movement. In addition to these factors, the sealant must be compatible with the substrates and able to maintain an expected life cycle under harsh conditions.

Some common types of high-performance sealants include silicones and polyurethanes. These chemistries have good resistance to temperature and water, as well as UV light. They are also able to resist abrasion, corrosion and other silicone sealant supplier chemicals. However, it is important to note that even within a specific sealant type there can be significant differences in performance capabilities.

When applying a high-performance sealant, it is important to follow the product’s application instructions. It is recommended that the joint surfaces be cleaned and free of oil, loose paint and other contaminants. Then, the sealant should be allowed to come to room temperature before tooling and gunning. It is important to apply the sealant in a smooth, continuous bead to achieve maximum adhesion.

Environmentally friendly

In addition to providing the benefits of strength, durability and UV resistance, eco-friendly sealants can help reduce your carbon footprint by minimizing energy waste. They can also prevent leakage, which could lead to structural damage and costly repairs. Additionally, they require fewer replacements than conventional sealants.

The main advantage of environmentally friendly sealants is that they do not release harmful chemicals into the air, unlike their solvent-based counterparts. These chemicals can be a health risk to humans, leading to throat silicone sealant supplier and eye irritation, headaches, nausea, and even some forms of cancer. This makes it important to use low-VOC products in well-ventilated spaces.

Some sealants contain recycled materials, which helps to reduce the demand for new resources and promotes responsible manufacturing practices. They are also low in VOCs, which means they do not contribute to ozone formation. This helps to mitigate the negative impact of smog and other air pollutants on human health.

Another option is a polyether-based silicone sealant, which does not contain harmful solvents or carcinogenic ingredients and can be used on most surfaces. These types of silicone caulking products are suitable for windows, doors, siding and vents, around pipes and wires, and in the bathroom or kitchen. They can be purchased at most home improvement stores and online. The least toxic is an oxime or alkoxy type neutral cure with no added mildewcide, such as ASI 388 (Amazon) or DuraSil (Green Design Center). However, both products still need to be applied in well-ventilated areas and should be cured in a dry environment.


Choosing the right silicone adhesive depends on the specific needs of your project. For example, you might need a sealant with high elongation or one that can resist abrasions. You may also need a sealant with low viscosity or one that can bond to a variety of surfaces. It’s important to work with a supplier that understands these characteristics and can help you choose the right product for your application.

Silicone sealants are highly versatile, and there is a lot of variation among different types. Some are formulated to bond a variety of materials and can be used as a paintable coating. Others are designed to withstand high temperatures and are ideal for electrical components and other high-performance applications.

Many silicone sealants are water-resistant, making them a popular choice for use outdoors. In addition, they do not promote mold growth and are easy to clean up when applied. They are also chemically unreactive and do not corrode. They are also a great choice for gluing objects together and can be used in hobbies and crafts, as well as in construction projects.

Master Bond offers an extensive line of high quality adhesive systems to meet the requirements of bonding, sealing, coating and encapsulation applications. These include epoxies, silicones and UV/LED curable systems. They are available in a variety of viscosities and cure mechanisms and offer a broad range of properties such as high temperature resistance, shear strength, chemical resistance, transparency and optical clarity.
