Acetoxy sealants are widely being used in a large number of applications in the construction industry. Where they are incompatible with specific substrates, they can be replaced by neutral cure systems. The alkoxy and oxime cure systems are available in either transparent (silica-filled composition only), or non-transparent/solid colour (silica-and/or chalk-filled composition containing appropriate pigment) versions. Their chemical neutrality enables these systems to offer a wide range of adhesive-bonding capabilities to... [Pg.472]

The RTV condensation ciue system consists of four types carboxylate cure, alk-oxide cure, oxime cure, and amine cure. For electronic applications, only the alkoxide cure system is preferred because the byproduct alcohol generated during cure is non-corrosive. [Pg.77]

In the global market, the acetoxy, methoxy, and oxime curing systems are the commercially predominant curing chemistries for one-component sealants. The tetrafunctional ethylor-thosilicate is used in two-component formulations. [Pg.524]

Resins blended with oximes of the current invention become cured when exposed to wavelengths between 190 and 700 nanometers. Sunlight or a Philips-TL05 or -TL09 fluorescent lamp have been used. Other related oxime photoinitiators are described (1). [Pg.483]

With these tools, it has been possible to develop a whole range of silicone sealants with cure kinetics designed for many different requirements (Fig. 11). The acetoxy sealants are fast curing, and thus well adapted to glazing applications. The oxime sealants are better suited for adhesion on plastics. For applications where a longer tooling time is required, such as expansion seals or perimeter joints, Alkoxy sealants have been developed with a longer skin-over time. [Pg.755]

Methyl isobutyl ketone has become increasingly important as a chemical feedstock. The oxime is used as an antiskinning agent in oxidatively drying paints, and the peroxide is used to cure unsaturated polyester resins. Methyl isobutyl ketone is an intermediate in the preparation of imidazolones and acetal esters. It is also used to block amines (ketimines) that act as moisture-initiated latent epoxy resin hardeners. Finally, alkaline autocondensation at elevated temperature yields higher molecular mass products that are employed as fragrances and perfumes. [Pg.360]
