Full article: Improving the adhesion strength of polymers: effect
Previous studies found that atmospheric plasma treatment improved the adhesion strength of polyethylene (PE), polyethylene terephthalate (PET), polyamide (PA), polyvinylidene fluoride (PVDF), polypropylene (PP), and high-density polyethylene (HDPE) [ 10, 13, 14 ].
US3975351A - Plasticizers as adhesion promoters in polyester/polyamide
The present invention relates to a process for improving the adhesion between normally non-adhesive components in a multi-component polymeric fiber by the addition of one or more defined plasticizers to one or more of the components.
Unsaturated Polyesters as New Solvent-Free Adhesion Promoters for High
The performance of these adhesion promoters was studied in different high solids systems, including a 1K alkyd metal topcoat, a 1K melamine-cured polyester stoving enamel, a 2K white polyurethane (PU) topcoat and a 2K epoxy primer. In these coatings, the main binders were partially replaced with PEAP 1600 or PEAP 1611.

The present invention relates to a process for improving the adhesion between normally non-adhesive components in a multi-component polymeric fiber by the addition of one or more defined plasticizers to one or more of the components.
Adhesion Promoters for Polymers
When adhesion promoters are used to increase the compatibility of two immiscible polymers, they are called Compatibilizers (mode of action). When adhesion promoters are used to increase the adhesion between a polymeric system and a filler, they are called Coupling Agents (mode of action). Chemically these are the same materials in both cases.
- What are polyester-based adhesion promoters (PEAPs)?
- Polyester-based adhesion promoters (PEAPs) are a series of modified UP resins that can partially replace the main binders in coatings formulations to improve their adhesion to difficult substrates.
- Which adhesion promoter is used in polymethacrylate plastisols?
- Basic vinylimidazoles, which are polymerized in as comonomers, are conventionally used as adhesion promoters for polymethacrylate plastisols. Polyaminoamides are optionally added to these PMMA plastisols as an additional adhesion promoter component. Other adhesion promoter additives for plastisols are also known. Aug. 26, 2004
- What is a polymer compatibilizer?
- Compatibilizers or coupling agents are chemical compounds that increase the compatibility of the polymer matrix and filler. The main function is to increase adhesion between the matrix and the filler (dispersed, fibrous or second polymer).
- How to increase adhesion between components of a mixture?
- It is possible to increase adhesion between the components of the mixture, as well as between organic and inorganic surfaces, through the use of adhesion promoters and compatibilizers, which are capable of entering into physical or chemical, as well as intermolecular or interatomic interactions with surfaces.
- How can a polymer improve adhesion?
- Other approaches to improve adhesion involve chemical modification of the polymer surface via oxidation with ozone or plasma, and physical abrasion of the inorganic substrate to increase the bonding surface area by altering the surface roughness.
- Do adhesion promoters work in high solids systems?
- The performance of these adhesion promoters was studied in different high solids systems, including a 1K alkyd metal topcoat, a 1K melamine-cured polyester stoving enamel, a 2K white polyurethane (PU) topcoat and a 2K epoxy primer. In these coatings, the main binders were partially replaced with PEAP 1600 or PEAP 1611.
