A hot formula / Michael E. O'Brien in ADHESIVES AGE, Vol. 44, N° 11 (11/2001)  

[article]  inADHESIVES AGE > Vol. 44, N° 11 (11/2001) . - p. 20-25 Titre : A hot formula : New polyols give manufacturers more processing versatility for polyurethane reactive hot melts Type de document : texte imprimé Auteurs : Michael E. O'Brien, Auteur ; D. Kip Hillshafer, Auteur ; Erik H. Williamson, Auteur Année de publication : 2001 Article en page(s) : p. 20-25 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Adhésifs thermofusibles Polyols Polyuréthanes Index. décimale : 668.3 Adhésifs et produits semblables Résumé : We have shown how orto-phthalate based esters can be successfully used in a PUR hot melt adhesive and offer versatility in these applications. This was done using a mixture design of experiments to find general trends in formulations using HDA, STEPANPOL PD-56 and agent 2272-100. Properties modeled included viscosity, open time, green strength and creep resistance. Also, the design of experiment approach allowed us to find optimized formulations for specific criteria. For example, it may be possible to increase the green strength of predominantly HDA-based with the addition of STEPANPOL PD-56. Also, the prosper combination of Agent 2272-100 and STEPANPOL PD-56 could simultaneously increase open time and green strength over an all-HDA based system. DSC scans of formulations that incorporated only STEPANPOL PD-56 or agent 2272-100 with HDA revealed different thermodynamics transitions that could be correlated with open time and green strength. Finally, quick stick testing was used to evaluate the bonding profile of two formulations using HDA/STEPANPOL PD-56 and HDA/STEPANPOL PD-56/agent 2272-100.

Hold your water / Craig E. Jansen in ADHESIVES AGE, Vol. 44, N° 11 (11/2001)  

[article]  inADHESIVES AGE > Vol. 44, N° 11 (11/2001) . - p. 30-36 Titre : Hold your water : New waterbone polychloroprene latices for adhesive applications Type de document : texte imprimé Auteurs : Craig E. Jansen, Auteur Année de publication : 2001 Article en page(s) : p. 30-36 Langues : Américain (ame) Catégories : Adhésifs en phase aqueuse Dispersions et suspensions Essais de pelage Latex Polychloroprène Polymérisation en émulsion Résistance thermique Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Polychloroprene latices have been utilized by the adhesives industry for many years for various applications, such as packaging, and to a limited extent bonding high-pressure laminate to particleboard. More recently, two-component adhesives based on polychloroprene latices have become widely used for bonding polyurethane foam to itself in the manufacture of seating. Polychloroprene latices have not widely replaced solvent-based contact cements in bonding high-pressure laminate to particleboard because of several performance and application issues. It rakes a waterborne adhesive much longer to dry at ambient conditions than a solvent-based adhesive. Quick drying of a latex-based system can only be achieved by an investment in drying equipment. The contact bond properties of polychloroprene latices are not as good as solvent-based polychloroprene adhesives in several respects. The difference in auto-adhesion properties gives lower initial bond strength and makes bonding at low pressures difficult. Also, the heat resistance of adhesives based on polychloroprene latices is generally lower than solvent-based contact cements because of the presence of surface active ingredients used to emulsify the latex, tackifiers and other compounding ingredients. This article presents two new polychloroprene latices that provide additional possibilities for formulating waterborne contact adhesives with good rack and heat resistance properties. By utilizing these latices in combination with other latices, formulations were developed that had improved initial peel strength and softening points.
