Longmore O187

Longmore O187 is a 3-glycidyloxypropyltrimethoxysilane by Shanghai LanMone New Material Technology. It acts as a coupling agent is mainly used to improve the adhesion between the surface of organic material and inorganic material. It improves mechanical strength, electric property of composite material and high retention in wet state. Longmore O187 is compatible with epoxy, phenol aldehyde, melamine, polysulfide, polyamino ester and polystyrene.

Hansen Solubility Parameters

[14.4, 4.7, 5.3]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Longmore O187. A practical determination of these HSP values would provide higher certainty. Learn More.
