Some years ago, when we added agar-agar to our catalogue, there was a lack of knowledge about the full range of its properties. After testing a multitude of grades available on the market, we finally could identify and choose the best grade of agar-agar that perfectly matches with our goals; that is “effective in cleaning and easy to be removed”: Agar-Art was born!
After considering Nano Estel as a consolidating agent, we focus on nanosilica properties as binders for inert and pigments.show
We are reporting a couple of case studies about evaluation of grouts, we think those publications had not enough visibility in spite of the interesting findings.show
Nano Estel: research in progress
Defining Nano Estel as a "new product" is a little bit forced, since that product has been added to our catalog in 2011. However, it is hardly surprising that restoration sector is rather "conservative" toward novelties.
For over 20 years C.T.S. has promoted and provided a unique product which is very popular among the restorers working on finds from archaeological sites. It is the well known B.D.G. 86, a ready-to-use neutral solution based on hydroxylammonium chloride and hydrazine (redox agents) and that is capable to clean stains of manganese.show
Despite the entry of synthetic resins such as aliphatic, urea-aldehyde, polyoxazole, that are characterized by high levels of stability and reversibility, vinyl based resins are still widely used in restoration because they gave birth to a multitude of adhesives and varnishes and consolidants that keep on excelling for specific applications. Their strength is the adhesive property, in fact Beva 371 is the most famous product. Nevertheless we cannot leave out of account white glue (Vinavil) for woody features and polyvinyl alcohol used as fixative for paint films of muralsshow
We are always attracted by innovations for two main reasons: firstly we wish to be continuously updated, then we are looking for something that let us 'forget' the solutions of the past.show
