Composition: JS-B315 is a polyester-modified polymethyl alkyl siloxane solution

       JS-B300 is a polyether-modified polydimethylsiloxane solution

Properties and Applications:

 

 

Product Name	Appearance	Density (25℃) g/cm³	Refractive Index (25℃)	Flash Point ℃	Solvent
JS-B315	Slightly yellow transparent liquid	0.92	1.4640	>100	Propylene glycol methyl ether acetate/Phenoxyethanol
JS-B300	Slightly yellow transparent liquid	0.895	1.4500	>25	Xylene/Isobutanol

JS-B315 slightly reduces the surface tension of the coating system, effectively improves flow and leveling, and exhibits a certain defoaming capability, helping to prevent Benard cell formation. Recommended Applications: JS-B315 is suitable for non-polar to medium-polarity coating systems, and is particularly recommended for automotive paints, automotive refinish paints, and industrial coatings.
JS-B300 is a standard leveling agent for solvent-based coatings.

 

Usage and Dosage: JS-B315 is used at 0.05-0.6% based on total formulation weight and can be added at any stage of the production process.

JS-B300 is used at 0.1-0.3% based on total formulation weight and can be added at any stage of the production process.
