“…HMAs generally consists of three main components: polymer base, tackifier, and plasticizer, but may contain other additives. [ 6,7 ] The most widely used polymer bases are polyethylene [ 8,9 ] and ethylene copolymers (poly(ethylene‐co‐vinyl acetate), poly(ethylene‐co‐ethyl acrylate), poly(ethylene‐co‐acrylic acid) [ 2,10‐12 ] ), polyisoprene, [ 13 ] polyester, [ 14 ] poly(vinyl acetate), [ 15 ] polyisobutylene, [ 16,17 ] polyamide, [ 18 ] polyurethane, [ 19,20 ] and polylactide. [ 21 ] The polymer base is composes more than half of the adhesive and is responsible for its strength, elasticity, viscosity, and adhesion.…”

The use of heavy crude oil asphaltenes and resins (termed asphaltenes) as the components of hot‐melt adhesives based on the styrene‐isoprene triblock copolymer was considered. The rheological, thermophysical, strength, and adhesive characteristics of the mixtures containing from 10 to 40 wt% of asphaltenes were studied. The addition of 10 to 20 wt% of asphaltenes enhanced the strength and adhesive properties of the mixtures and only slightly changed their rheology. The higher concentrations of asphaltenes reduced the viscosity of the mixtures but did not lead to improved characteristics of the adhesives. The ambiguous effect of asphaltenes is probably due to their uneven distribution between the microphases of the block copolymer as well as their ability to act both plasticizers and reinforcing particles depending on temperature. A comparison of asphaltenes and conventional tackifiers based on hydrocarbon resins revealed their comparable effect on the properties of the block copolymer.

“…Li et al [ 139 ] report a method to improve the adhesion strength and water resistance of stainless steel and ethylene acrylic acid/linear low-density polyethylene (EAA/LLDPE) blend film composites by using functionalized silane as a surface modifier. They found that the EAA/LLDPE (60:40) blend had the best balance of strength and toughness among the blends.…”

Hot-melt adhesives (HMAs) are thermoplastic materials that can bond various substrates by solidifying rapidly upon cooling from the molten state, and their modification with organosilicon compounds can result in crosslinking behavior, characteristic of gels. Organosilicon compounds are hybrid molecules that have both inorganic and organic components and can enhance the properties and performance of HMAs. The gel aspect of HMA with and without organosilicon modifiers can be considered in organosilicon-modified systems, the modifiers are often either sol–gel condensation products or their mechanism of action on the adherent surface can be considered of sol–gel type. The purpose of this manuscript is to present the current state of the art on the formulation, characterization, and application of HMAs and optimize their performance with organosilicon compounds for application in various industries such as automotive, construction, and photovoltaics. This review covers articles published within the period of 2018–2022. The article is divided into sections, in which information about hot-melt adhesives is described at the beginning. The following part of the presented review focuses on the composition of hot-melt adhesives, which takes into account the use of organosilicon compounds. The last part of this review outlines the future trends in hot-melt adhesives.

“…However, for steel pipes, the low adhesion between these polymers and steel represents a significant challenge. 12,13 To address this issue, epoxy has emerged as a promising option due to its superior adhesive properties to metallic surfaces 14,15 and economic justifications as the binder between HSS and pipe. The insufficient compatibility between pure polyolefins and epoxy compromises their adhesion issues, rendering the use of an intervening third material indispensable to produce a composite material that satisfies all essential criteria for HSS.…”

Heat shrink sleeves (HSS) are multilayer polymers that provide corrosion resistance for welding joints of steel pipes. Within the HSS structure, the adhesive layer is a blend of components, such as ethylene vinyl acetate (EVA) and linear low‐density polyethylene (LLDPE). In this study, a systematic approach was employed to investigate the effect of the rheology and blend composition of the maleic anhydride‐modified EVA and maleic anhydride‐modified LLDPE (EVA‐g‐MA/LLDPE‐g‐MA) adhesive layer, prepared by melt processing, on its adhesion properties. Various characterization techniques were employed to investigate the local morphology of the prepared blends at different zones. Peel strength tests were used to characterize the adhesion strength of the prepared adhesives. Our findings demonstrate that the local distribution of EVA‐g‐MA within LLDPE‐g‐MA plays a crucial role in the adhesion strength of the adhesive. The results show that the adhesion strength enhanced by nearly 45% as the composition of EVA‐g‐MA at the surface went up by 20%, shifting the failure location from the epoxy/adhesive interface to the bulk of the adhesive layer. Our hypothesis of the decrease of EVA‐g‐MA intrachain bonding and increase in the EVA‐g‐MA free chain amount in the presence of LLDPE‐g‐MA to improve the adhesion properties was corroborated through our calorimetry results where the relative EVA‐g‐MA crystallinity decreased as LLDPE‐g‐MA was introduced to the blend. The findings of our study highlight the importance of rheological behavior and blend composition in obtaining optimized performance of adhesives within the HSS structure.Highlights Compression molding of EVA‐g‐MA/LLDPE‐g‐MA induces a layered morphology. Local distribution EVA‐g‐MA/LLDPE‐g‐MA components influence their adhesion. EVA‐g‐MA at the interface improves the adhesion of EVA‐g‐MA/LLDPE‐g‐MA. LLDPE‐g‐MA suppresses the EVA‐g‐MA crystallinity. EVA‐g‐MA/LLDPE‐g‐MA composition affects adhesion at different temperatures.
