Chemical Structure

Introduction

DP-A212 is a colorless, strongly alkaline liquid with amine smell being very sensitive to hydrolysis.

DP-A212 is a diamino-functional silane capable of providing good adhesion and superior elougation and flexibility at the polymer-substrate interface. It is used to promote adhesion between glass, mineral and metal surfaces - reinforcements, fillers and substrates - and resins that react with amino groups in systems such as PVC plastisol, polyurethane, or epoxy-based adhesives and sealant, or in phenolic and epoxy molding compounds. Its reduced alkoxy functionality might also be useful in waterborne systems such as latex coatings, adhesives and sealants, providing lower reactivity and therefore higher stability in the aqueous environment.

Typical Physical Properties

Solubility:DP-A212 is easily soluble in water with spontaneous hydrolysis occurring. Caution: Due to solution enthalpies mixing water is exothermic. Always stir DP-A212 into water. With alcohols miscibility is, in general, possible with self-catalyzed exchange of the alkoxy-groups. In aliphatic and aromatic hydrocarbons and (moisture-free!) ethers or esters DP-A212 is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates DP-A212 shows typical amine function. Some nonferrous metals can discolor upon contact.

Applications

DP-A212 can be used as adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two-part urethanes and epoxy adhesives and sealants.

DP-A212 can be used as additives for cold-curing phenolic and furan foundry resins to improve the flexural strength of the sand-resin composites while

DP-A212 can be used as starting material in the synthesis of amino-functional silicones

DP-A212 can be used as additives to latex coatings, adhesives and sealants.

DP-A212 can be used as adhesion promoters in one-part silylated urethane adhesives and sealants.
