Température -- ContrôleIndex. décimale : 667.9 Revêtements et enduits Résumé : Not getting the cure schedule right could increase the true costs to a company significantly and affect its whole operation. Datapaq has designed oven profiling systems that can maximise process efficiency.
The majority of temperature profiling systems used today is employed to simply check that the coated product reaches and maintains the specified temperature for the correct time (dwell time), ensuring the coating is thermally cured. This, in its own right is an essential step to improving operating profit by simply reducing the risk of rejects or need for costly rework. Not getting the cure schedule right could increase the true costs to a company significantly and affect its whole operation ; labour, energy, coatings and risk of lost contracts. Guaranteeing cure quality is the mere tip of the ice-berg in terms of how profiling can help you achieve the full potential of your coating operation as this article intends to discuss. Improve operating efficiency by understanding and controlling thermal cure process can maximise a company's operating profitability.Note de contenu : - Oven control - cost saving potential

Stimulation électriqueIndex. décimale : 667.9 Revêtements et enduits Résumé : This article describes the use of thermally stimulated electrical discharge (TSD) measurements in the study of the cure processes occurring for a range of titanium dioxide, silica, and zinc oxide-pigmented epoxy polyester films. The unfilled polyester–epoxy resin system exhibits a simple TSD profile indicative of a combination of space charge and dipole relaxation processes. The addition of the Modaflow, which is used to aid in the dispersion of the pigment in the system, induces phase separation under certain cure conditions. In a number of systems, two lower temperature Tg peaks were initially observed, which collapsed into a single peak on post cure. The principal difference between the two grades of titanium dioxide was the size of the space charge peak, which is a direct indication of the mobile ion content in the material. The sulfate has higher mobile ion content than the chloride route material. Differences were observed between traces of silica and zinc oxide, which reflect the ability of the particles to interact with the resin and form a dense matrix. Silica at low concentrations is able to reduce the space charge peak which implies it can trap ions. The TSD study indicates that the pigments are able to change the morphology of the matrix which is being formed.

RhéologieIndex. décimale : 667.9 Revêtements et enduits Résumé : Interest in finding alternatives to TGIC-based powder coatings have driven development of alternate binders for the exterior durable powder coating market. Thermoset powder coatings utilizing carboxylic acid functional polyester resins cared with epoxide-functional acrylate polymers have been evaluated and characterized. Modification of the composition and molecular weight of either component influences the physical properties of formulated powder coating. The behavior of these coatings during the cure process has been investigated and compared with polyester/TGIC. systems. Note de contenu : - INTRODUCTION : Acrylate-cured polyester powder coatings

Revêtements -- Séchage sous rayonnement ultraviolet
Revêtements poudreIndex. décimale : 667.9 Revêtements et enduits Résumé : In UV curable powder coatings the UV absorbance of pigments (and additives) directly affects the film formation. In this study, the influence of TiO2 pigmentation level and layer thickness on the coatings properties were monitored by ATR-FTIR spectroscopy, UV light transmission, glass transition temperature measurements, coating hardness and abrasion, as well as differential photocalorimetry. increasing the pigment level or coating layer thickness leads to a decrease in through cure. Maximum coating thicknesses for complete through cure are given for various formulations. Note de contenu : - Semi-crystalline binders show better flow at low temperatures
- Temperature limits must be observed
- Application and curing parameters on MDF
- Detailed study of pigment concentration effects
- ATR-FTIR measurements
- Curing results can depend on lamp type
- Limited UV transmission does not imply bad through cure
- Incomplete cured coatings show lower Tg
- Hardness and through cure closely related
- Pigment level determines the abrasion resistance
- Several effects lower reaction enthalpy with higher pigmentationEn ligne : https://drive.google.com/file/d/1uPSI4Y6YaGv1thmPDGRuTKI0qQm3_u6J/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10772
