Introduction
3-(2-Aminoethylamino)propyl-dimethoxymethylsilane is a colorless, strongly alkaline liquid with amine smell being very sensitive to hydrolysis.
3-(2-Aminoethylamino)propyl-dimethoxymethylsilane 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. Applications:
3-(2-Aminoethylamino)propyl-dimethoxymethylsilane can be used as adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two-part urethanes and epoxy adhesives and sealants.
Used as additives for cold-curing phenolic and furan foundry resins to improve the flexural strength of the sand-resin composites while;
Used to maintain the shelf life of the resin over long periods;
Used as starting material in the synthesis of amino-functional silicones;
Used as additives to latex coatings, adhesives and sealants;
Used as adhesion promoters in one-part silylated urethane adhesives and sealants.

Check Digit Verification of cas no
The CAS Registry Mumber 3069-29-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,6 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3069-29:
(6*3)+(5*0)+(4*6)+(3*9)+(2*2)+(1*9)=82
82 % 10 = 2
So 3069-29-2 is a valid CAS Registry Number.
