Application of Industrial Sealant

Features of Waterproof Sealant

With the rapid development of economy and technology, technical requirements of each industries are increasing day by day. Sealant is a kind of special glue indispensable in many industries. Such as electrical/electronic industry, packaging industry, aerospace industry and architectural industry etc. Among them, the common widely used waterproof sealant is mainly applied to the adhesive bonding of sanitary products, outdoor daily things, ship parts and other water supplies. The waterproof sealant has many good characteristics: good waterproof performance is the most important feature of waterproof sealant, in addition, it has excellent viscosity, is a non-toxic, tasteless, non-combustible, non-polluting, environmentally friendly polymers waterproof sealant. It also has excellent permeability, water penetration resistance, corrosion resistance, abrasion resistance and weather resistance, its construction is quick and easy, save time, save labor and save strength, low cost and superior waterproof effect.
　
Basics of Glass Sealant

Glass Sealant is a kind of senior silicone sealant of single component, low modulus and acid-curing multipurpose. Generally, it is suitable for the sealing for glass and other materials. You must test its adhesion, compatibility and pollution of the substrate before using it. The use of the product effect depending on the specific substrate used. And it has strict restrictions on Use: the surface of construction materials must be clean and dry; prohibit to use in structural applications; ban to contact with the insulating glass sealant and does not apply to the sealing of long-term flooding, airtight or the surface permeability material; not fully applicable to ceramics and other porous materials. The surface temperature should be between 15 ℃ ~ 27 ℃ when construction. Emergency treatment: when it comes to eye or skin, immediately rinse it with water. If have adverse reaction, should go seek medical care immediately. The silicone adhesive in the curing stage will release acetic acid (vinegar-like taste), and the fully cured silicone rubber is not toxic.

　 Classification of Glass Sealants

There are various glass sealant in the market, it can be divided into different categories accordingly. Divided by the components: single-component and double-components. The single components silicone glass sealant, its curing is happened by exposure to moisture in the air and produce changes in physical properties; double-component refers to the silicone rubber is divided into two groups (A, B), any stand-alone group can not form a curing and the two groups will produce curing once they mix together. On the market now what we commonly see is the one-component silicone glass sealant: one-component silicone glass sealant properties are divided into acidic gum and two neutral plastic. Acidic glass sealant is mainly used for general bonding between the glass and other building materials. Neutral sealant to overcomes the acidic adhesive corrosion of metal materials and features to react with alkaline materials, and therefore its application is more broad and the market price is slightly higher than the acid sealant.
