Clear Sealants

Sealants with Kraton® polymers can be pigmented or are readily paintable. To match dissimilar color surfaces, they can be formulated clear as well. The polymers also provide good low temperature performance yet can be formulated to boost upper service temperature at same time.

Features and Benefits

The unique properties and wide grade range of Kraton® polymers provide the customer different options for the sealant markets. 

• Can be pigmented, painted, or remain clear
• Flexible low temperatures
• Elongation and elasticity
• Adhesion to a wide variety of substrates
• Good thixotropic characteristics
• Kraton G and Kraton A polymer grades offer improved weatherability, color, and heat stability
• Kraton FG polymer grades yield better adhesion to polar substrates such as glass and aluminum

Products

Clear Sealant: The sealant is typically applied from a hand held caulking gun for small or spot applications and pressure gun for larger industrial applications. The sealant is usually applied to surfaces exposed to weather elements such as windows. They provide good adhesion to keep moisture out.  Kraton G1652, G1701, G1726 polymers typically are used.

Hot Melt Sealant: Kraton G1657 polymer has a lower viscosity and is thus more suitable for hot melt applications. It can be formulated to provide improved adhesion as well as.
