Selecting Plasticizers for Adhesives and Sealants
Plasticizers generally affect the viscoelastic properties of the base resin; whereas, diluents would simply reduce the viscosity of the system. Whereas diluents ultimately result in brittle, hard adhesive systems, plasticizers result in increased flexibility and lower modulus.
Influence of plasticizers on the adhesive properties of an
The influence of plasticizers in film coating formulations on the adhesive properties of an acrylic resin copolymer was determined using the butt adhesion technique. Hydrophilic and hydrophobic plasticizing agents were incorporated into aqueous dispersions of Eudragit L 30 D-55 and coated onto hydrophilic and hydrophobic tablet compacts.
Influence of Plasticizers on the Properties of Natural
The influence of the chemical structure of the oil (paraffinic, naphthenic and aromatic) and oil loading on carbon black and silica filled compounds was studied considering the following aspects:...
The effect of plasticizers on properties of epoxy-thiokol
It is shown that the introduction of plasticizers into the composition increases the adhesive and cohesive strength, tensile strain, and fracture energy of the material. The use of oligoetheracrylate MGF-9 as a plasticizer allows the greatest effect to be achieved. Download to read the full article text References

- Do plasticizers affect acrylic pressure-sensitive adhesive performance?
- The use of plasticizers and their influence on acrylic pressure-sensitive adhesive (PSA) performance are discussed. Plasticizers can be used as components in the pressure-sensitive adhesive technology for tackification of self-adhesive performances.
- Do plasticizers increase elasticity and adhesiveness of hydrogels?
- The addition of plasticizers, namely PEG and PG, resulted in a simultaneous increase in elasticity and adhesiveness of these hydrogels, viathe formation of hydrogen bonds, which has a direct correlation with their adhesion properties.
- Are UV-curable pressure sensitive adhesive films suitable for dermatological applications?
- UV-curable pressure sensitive adhesive films: effects of biocompatible plasticizers on mechanical and adhesion properties - Soft Matter (RSC Publishing) We developed a new approach to fabricate pressure sensitive adhesive (PSA) hydrogel films for dermatological applications.
- What is plasticizer resistance?
- Plasticizer resistance is an important feature of PSA, especially by commercial application of acrylic PSA. The plasticizers are added for PSA formulations for softening or viscosity reduction of the coatable adhesive. The acrylic PSA are compatible with organic phosphates, glycolates, chlorinated amides, and polyalkylene glycols.
- What are plasticizers used for?
- Plasticizers can be used as components in the pressure-sensitive adhesive technology for tackification of self-adhesive performances. Plasticizer resistance is an important feature of PSA, especially by commercial application of acrylic PSA.
- How does plasticizer migration affect the environment?
- Plasticizer migration can lead to degradation of properties during the life of the adhesive, cause transfer of the plasticizer to unwanted surfaces (e.g., fogging of windshields in autos or contamination of electronic substrates), and it can also adversely affect the environment. The key characteristic for migration is molecular size.
