Solvent - based SBS adhesive low viscosity solution
Solvent - based SBS adhesive low viscosity solution.
Reasons for low viscosity of solvent - based SBS adhesive:
1.The type of SBS was not correctly selected.
2.Selection of S/B ratio
3.Poor coordination of line and star SBS.
Effects of solvent - based SBS adhesive on low viscosity: Construction performance is limited.
Solution of low viscosity of solvent - based SBS adhesive:
SBS mainly have two kinds of molecular configurations, such as star and linear, with large molecular weight, usually in the range of 15-300 thousand, and the viscosity is large after dissolution.The linear SBS molecular weight is small, generally within the range of 8-120,000, with low viscosity.The size of SBS molecular weight and its distribution have certain influence on viscosity and bonding strength.
The molecular weight is small, the activity capacity of the molecule is strong, and the wet strength of the adhesive is strong.However, low molecular weight can make SBS lack sufficient cohesion strength and reduce bonding strength.Therefore, when preparing the adhesive, the linear or star SBS can be selected according to the need, and the molecular weight is moderate, and S/B value is suitable for the base material of SBS.This can avoid high - solid low viscosity and high cost, poor performance of products.
