Description

Silanediol, 3-(2-Aminoethyl)Aminopropylmethyl-, Potassium Salt is a specialized organosilicon compound featuring a unique bifunctional structure with both silanediol and aminoalkyl groups. This molecular architecture makes it a highly effective coupling agent and surface modifier, crucial for enhancing adhesion and compatibility in composite materials. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science for surface treatment and polymer modification.

Application

• As a powerful adhesion promoter in epoxy, polyurethane, and acrylic-based coatings and adhesives.
• As a surface modifier and coupling agent for inorganic fillers (e.g., silica, glass) in polymer composites to improve dispersion and mechanical properties.
• In the formulation of primers and tie-layers to enhance bonding between dissimilar substrates like metals, glass, and plastics.
• For the functionalization of nanoparticles and other advanced materials to introduce reactive amine groups.
• As an intermediate in the synthesis of more complex silane-based specialty chemicals.
• In water-based systems where its potassium salt form offers improved solubility and handling.
