Abstract：

SCA-MA10E is a masked aminosilane and can be to triggered the demasking with moisture. This masked aminosilane can stably exist in isocyanate, epoxy, acrylic and other amino-reactive resins but, when exposed to any form of water, hydrolysis occurs rapidly. The ketone byproduct escapes to leave an activated primary amine.

To take advantage of these above characteristics, aminosilanes can now be used as additives for formulated resins that usually are not compatible with aminosilanes, such as epoxy, isocyanate, acrylic, UV or phenol for paints, adhesives and surface treating agents. These new formulations enable good adhesion and reinforcement while enabling one-component packaging systems. 

Applications and Performance：

Maximum bond strength in some adhesion and bonding systems requires that the organic functionality of a silane coupling agent becomes available during a discrete time period of substrate - matrix contact.

Examples are epoxy adhesives in which reaction of the silane with the resin increases viscosity of an adhesive to the extent that substrate wet-out is inhibited and pretreated fillers for composites which can react prematurely with moisture before melt compounding or vulcanization. A general approach is to mask the organic functionality of the silane which converts it to a storage-stable form and then to trigger the demasking with moisture, or heat concomitant with bonding or composite formation.

For example single-component liquid-cure epoxy adhesives and coatings employ dimethylbutylidene blocked amino silanes SCA-MA10E. It shows excellent storage stability in resin systems, but is activated by moisture provided by water adsorbed on substrate surfaces or from humidity. Deblocking begins in minutes and is generally complete within two hours in sections with a thickness of less than 1mm.

In different applications, SCA-MA10E can be used as adhesion promoters, crosslinking agents and surface modifiers for pigments and fillers, etc.. It can be used for a variety of solvent-based inks, coatings, adhesives and other resin coatings and resin-based composite materials based on the epoxy, isocyanate, acrylic, UV or phenol resins.
