Industrial Sealants - Henkel Adhesives
Industrial silicone sealants and adhesives may be used in a wide array of applications, particularly in the automotive industry. Henkel offers a several types of industrial silicone sealants that range from high performance sealants for vehicle assembly to general purpose applications.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are used in all types of adhesive and sealant formulations. They are used primarily to the final bond and to provide improved low-temperature properties. However, plasticizers can also supply additional benefits that are important to both the formulator and end-user.
New silane-terminated polymers for sealants and adhesives
GENIOSIL XM 20 is an alpha-silane-terminated polyether that allows the formulation of plasticizer-free, elastic adhesives with extremely high elasticity. Typical applications include wood-flooring adhesives and all-round adhesive sealants. Full size image Glossary Modulus The modulus provides information on the stress-strain behavior of a material.

- What is a plasticizer used for?
- Plasticizers have been used to give polymers a permanent adhesive character (pressure sensitivity), or to regulate their adhesion-cohesion balance to achieve removability. For example, plasticizers can be incorporated into peelable pressure-sensitive adhesive to soften the adhesive, and thus improve peelability and clean removal.
- What types of plasticizers are used in adhesives & sealants?
- Oils (like paraffinic, naphthenic, and aromatic) are used mainly as plasticizers in non-polar adhesives. These are generally used in the hot-melt adhesives and sealants. Base polymers include the mid-blocks of styrene-butadiene copolymers and polyolefin-based adhesives. Polymeric plasticizers are used frequently in adhesives and sealants.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- Why should you choose a plasticizer that is compatible with polymer?
- By choosing a plasticizer that is compatible with the polymer, it protects the plasticizer for leaching out of the product and thus losing the benefits of plasticization. Plasticizer permanence, or resistance to migration out of the adhesive or sealant, plays a role in the longevity of a product.
- Why are plasticizers used as extenders?
- Plasticizers may also be one of the least expensive additives used in adhesives and sealants, and they can be used in relatively large concentrations depending on the application and formulation (up to 100 parts by weight per 100 parts of the base polymer). For these reasons, they are sometimes used as extenders for cost-reducing purposes.
- Do plasticizers reduce the viscosity of adhesives & sealants?
- Plasticizers will reduce the melt viscosity of hot-melt adhesives and 100% solids adhesives & sealants. However, the addition of certain plasticizers to a polymeric emulsion will usually result in increased viscosity. This effect can be used to formulate a waterborne adhesive having greater coating thickness build-up.
