Characterization of commercial synthetic resins by pyrolysis-gas chromatography/mass spectrometry : application to modern art and conservation [PDF]

open access: yes, 2009
To characterize a set of synthetic resins, a methodology by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) has been developed. The studied reference materials were commercial versions of a wide range of synthetic resins.

Carbonation of surface protected concrete [PDF]

open access: yes, 2013
Concrete structures are exposed to carbonation that may cause rapid decay, shortening their service life and raising maintenance and repair costs. Carbonation lowers the alkalinity of the concrete depassivating the steel reinforcement.

Development of a special purpose spacecraft interior coating, phase 3 [PDF]

open access: yes
A variety of intumescent coatings based on a fluorocarbon latex resin modified with either an acrylic resin or an epoxy resin were prepared. Several intumescent systems were used for these studies including some based on ammonium polyphosphate and others

Use of water-based carbonyl-functional polymers on a cross-linker-free highperformance leather finish [PDF]

open access: yes, 2011
The present paper aims to study a new high-performance coating formulation while avoiding the use of cross-linkers. By using acrylic polymers with carbonyl functional groups, the negative environmental effects of the finishing process can be minimized ...

One-Pot Synthesis of Waterborne Polymeric Dispersions Stabilized with Alkali-Soluble Resins [PDF]

open access: yes, 2018
Alkali-soluble resins (ASRs) are a type of electrosteric emulsifiers of high interest because they can profitably improve the features of waterborne dispersions.

Waterborne hyperbranched alkyd-acrylic resin obtained by miniemulsion polymerization

open access: yesPolímeros
Four waterborne hyperbranched alkyd-acrylic resins (HBRAA) were synthesized by miniemulsion polymerization from a hyperbranched alkyd resin (HBR), methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA), by using benzoyl peroxide (BPO) and ...

PBO Fibres: from saliling design towards architectural performance

open access: yes, 2009
p. 3013-3023PBO fibres, also called "high-performance" polymer fibres, are a group of materials known as "rigid rods". Through this work it is pretended to make some considerations about the use of these new generation fibres.

Effect of the Incorporation of Compounds into Digitally Manufactured Dental Materials—A Systematic Review

open access: yesApplied Sciences
The aim of this review was to evaluate if the properties of digitally produced dental acrylic resins improved when reinforced with compounds. A literature search was conducted in PubMed, Web of Science, and Scopus databases for the past 10 years ...
