When used in combination with conventional silane coupling agents, N,N-bis(3-Trimethoxysilylpropyl)urea provides the necessary functionality for specific applications while also offering increased durability due to its higher hydrolytic stability. This combination is particularly beneficial in various industrial applications where strong and long-lasting bonds between organic and inorganic materials are required.
Structure and conformation
Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete.
Check Digit Verification of cas no
The CAS Registry Mumber 18418-53-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,1 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18418-53:
(7*1)+(6*8)+(5*4)+(4*1)+(3*8)+(2*5)+(1*3)=116
116 % 10 = 6
So 18418-53-6 is a valid CAS Registry Number.
