The Development of Sustainable Internal Curing Agents Using Natural Hollow Fibres
… of superabsorbent materials as internal curing agents has demonstrated effectiveness in mitigating self-desiccation and early-age cracking in cement mixes characterized by low water-to-binder ratios (w/b). However, concerns related to sustainability, availability, and cost have emerged, …

The characterisation of Manganese (IV) compounds and the study of the thermal decomposition of Potassium Chlorate alone and with Mn(IV) and other oxides and salts
Manganese dioxide compounds are preferred curing agents for Polysulphide resins used as sealants in industry. These are required to have consistent setting characteristics and the investigation was initiated to characterise a number of proffered compounds of this type an to establish criteria by …

Generic studies on the oxytetracycline producing organism, Streptomyces alboflavus
… the antibiotic oxytetracycline. Treatment with curing agents resulted in S. alboflavus losing the ability to produce oxytetracycline. However, the loss of oxytetracyc1ine production was reversible, and non-producing colonies regained the ability to produce oxytetracycline when the curing agent …

Using Saccharomyces cerevisiae to characterise the in vivo effects of exposure to the prion-curing drug Tacrine and the fungal metabolite gliotoxin
… In this study, the effects of three prion-curing agents, Tacrine, 6-aminophenanthridine and Guanabenz on [PSI+] have been studied. The ability of all three drugs to cure [PSI+] has been demonstrated. From investigating the Tacrine mode of action, it appears that this drug may inhibit …

Doped Layered Phosphate Catalysts for the Activation of Glycerol
… polymers and cleaning solvents to cosmetics and curing agents. Recent research has started to focus on finding new green methods for synthesising glycerol carbonate, by way of catalysis. Previous work in this area was carried out by Aresta et al. in which γ-zirconium phosphate was used to …

Analysis and characterisation of an acylphosphine oxide photoinitiator
… monomers and they are very widely applied as curing agents for white and pigmented coatings including furniture coatings. Novel analytical methods were developed in order to characterise these compounds and to understand their modes of action and breakdown. The stability of BAPO in different …

Epoxy + Liquid Crystalline Epoxy Coreacted Networks
… and subsequently cured with anhydride and amine curing agents. Curing kinetics were determined using differential scanning calorimetry (DSC). Parameters for autocatalytic curing kinetics of both pure monomers and blended systems were determined. The extent of cure for both monomers was monitored …

Influences on nanocomposite structural performance: experimental study on materials processing and bonding
… Microscopic<br/>observations of the resin before curing shows agglomerated nanoclay visible in the samples<br/>which decreases as the shearing time. Comparing the processing methods showed greater<br/>dispersion in the bead mill processed samples. TEM and X-ray diffraction were used to<br/>measure …

Développement de nouveaux produits époxy biosourcés à base de dioxyde de limonène
… Several epoxy monomers and two different curing agents were used in a new LDO based formulation, and were compared with industrial formulations containing DGEBA.3 When preparing an epoxy polymer, the time it takes to transform the liquid mixture to solid polymer (reaction time) is a …

Fabricating Complex-Shaped Components by Room-Temperature Injection Molding of Aqueous Ceramic Suspension Gels
… without the use of any harsh crosslinking or curing agents or further chemical processes. The development of room-temperature injection molding initially focused on forming CeraSGels based on alumina, a readily available model material, in order to optimize suspension preparation and …
