Material guide
Silane coupling agents
Compare amino and epoxy silanes using chemical identity, CAS number, listed purity and applications in coatings, adhesives and sealants.
The selected silanes include amino-functional materials and an epoxy-functional material. Their catalog applications cover coatings, adhesives and sealants, with additional uses listed for individual models.
VN-SI-1087 is 3-aminopropyltrimethoxysilane; VN-SI-1088 is 3-aminopropyltriethoxysilane. VN-SI-1089 carries an epoxy group, while VN-SI-1092 is N-(2-aminoethyl)-3-aminopropyltrimethoxysilane. Use the chemical name and CAS together when specifying a material.
What to check when selecting
- Match the functional group to your resin, substrate and process; a common application label does not demonstrate interchangeability.
- Check the listed purity: VN-SI-1087 is minimum 97.0%; the other three selected models are minimum 98.0%.
- Provide the formulation medium, substrate and curing conditions when requesting guidance on treatment or addition level.

Selection questions
How do VN-SI-1087 and VN-SI-1088 differ?
VN-SI-1087 is the trimethoxy material, CAS 13822-56-5. VN-SI-1088 is the triethoxy material, CAS 919-30-2. Their listed minimum purities also differ.
Is there one addition level for all four silanes?
The current product pages do not specify a common addition level. Establish the level through formulation trials using the current technical guidance for your selected model.
