Construction Mastics/Caulks
The properties and wide grade range of Kraton® polymers provide the customer different options for construction adhesives.
Features and Benefits
Kraton polymers have advantages to conventional elastomers:
- Can be highly filled or pigmented
- Flexible at low temperatures
- Highly elastic and resilient
- Resistant to most acids and bases
- Kraton polymers with high diblock can be used in flooring mastics where low viscosity and low cohesive strength is important
- Kraton polymers with high molecular weight and high styrene provide extendibility and good load bearing performance
Products
Construction adhesive: The adhesive is typically applied from a hand held caulking gun for small or spot applications and pressure gun for larger industrial applications. The adhesive is applied to areas where strength and load bearing performance is needed such a wall panels. Construction adhesive can hold fixtures in place till better secured.For some applications adhesive can replace nails. Kraton D SBS polymers are typically used since most applications do not need heat or weatherability performance. Kraton polymers such as D1116 can be formulated to adhere to polystyrene foam with specific solvents that reduce attack to the foam.
Flooring mastic: Mastic formulas with Kraton polymers can be applied to various substrates including floor or carpet tiles for adhesion performance. The high diblock polymers can be formulated to reduce “squeaking” between floors also. Kraton D polymers are typically used but Kraton G and A polymers can be used if temperature or weather stability is needed.
