Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Architectural exterior coatings are subject to the harsh elements of the environment. Careful consideration must be paid to these harsh conditions to overcome deleterious effects of these elements. The novel polymer developed using innovative polymer engineering has outstanding performance for paint and primer in one exterior coatings application. This polymer can be used to formulate <25 g/l VOC coatings. A benchmark study involving market leading competitive binders shows that the novel polymer outperforms in DPUR, leaching resistance, tannin blocking, efflorescence resistance, scrub resistance, corrosion resistance, gloss retention, and tint strength. Natural weathering shows excellent results at 36 months of testing.

Teinture -- Fibres textiles synthétiques
Textiles et tissus -- Propriétés mécaniquesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Polyethylene terephthalate nanocomposites containing six modified montmorillonite nanoclays were prepared by a melt compounding technique. The effect of intercalated compounds of montmorillonite on textile mechanical properties of resultant polyethylene terephthalate nanocomposite fabrics was investigated. Winding was not possible, when the polymers were first compounded with the desired amount of montmorillonite and then spun, as filament breakage occurred. Spinable polymer were only obtained by mixing polyethylene terephthalate master batches with 4 wt% montmorillonite, which contained tallow intercalating compound with pure untreated polyethylene terephthalate to a montmorillonite content of 0.5 wt%, thus decreasing the concentration of thermally degraded polymer chains. After spinning the fibres were drawn and knitted into fabric samples for further testing. The prepared polyethylene terephthalate nanocomposite fabrics using montmorillonite exhibited higher colour strength using vat and disperse dyes compared with those of the reference fabrics made from fibres spun without montmorillonite clay content and regular fabrics. The carbocyclic‐based vat dyes have higher colour strength values on polyethylene terephthalate nanocomposite fabrics if compared with heterocyclic‐based vat dyes. The colour fastness ratings for both vat and disperse dyeings secured very good to excellent washing and perspiration fastness on polyethylene terephthalate nanocomposite fabrics. All dyed fabrics showed excellent light fastness using vat and disperse dyes. The preparation of polyethylene terephthalate nanocomposite fabrics with improved textile mechanical and vat dyeing properties needs further investigations.
