Plasticizers are an important component of many adhesives and sealants. A plasticizer is an additive used to increase flexibility or workability of a polymer system. Plasticizers typically affect the viscosity, lower the glass transition temperature, and lower the elastic modulus of a product.
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.
DINP Usage Guide - Chemceed
Diisononyl phthalate, also referred to as DINP, is a plasticizer used in a variety of materials for a diverse array of industrial applications. DINP is commonly associated with PVC plastics and vinyls employed in the adhesive, construction, and manufacturing industries.
Eastman Plasticizers for Adhesives
Admex 6995 is a medium molecular weight, light colored, polymeric adipate with a mild ester odor. Benzoflex 9-88 is a high solvating benzoate ester plasticizer that can be used in a wide variety of polymer systems and applications. Its diverse uses include resilient flooring, adhesives, caulks, and sealants.
- 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.
- 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.
- What is a plasticizer used for?
- A plasticizer is an additive used to increase flexibility or workability of a polymer system. Plasticizers typically affect the viscosity, lower the glass transition temperature, and lower the elastic modulus of a product. Phthalates and terephthalates are an example of effective plasticizer chemistries used in caulks and sealants.
- 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.
- What is plasticizer permanence?
- Plasticizer permanence, or resistance to migration out of the adhesive or sealant, plays a role in the longevity of a product. Permanence can be affected by weathering such exposure to sunlight and extreme temperatures, or extraction by substances such as soapy water.
- What is plasticizer compatibility?
- Plasticizer compatibility is the key to plasticizer performance in adhesives and sealants. In latex systems, compatibility can be assessed by observing the viscosity increase after the addition of the plasticizer and by observing the clarity of a cast film of the plasticized adhesives.
