PAG quenching medium

High viscosity water soluble PAG,control the cooling parameters curve By adjusting molar mass and concentration of polymer.

The clear liquid and light color product makes the clarity and transparent final product. Excellent cleaning property,convenient to clean the workpiece after quenching.

Good stability.Long service life,reduce cost.

A wide selection of products,adapt to different processing conditions

Unique customized processing,the cooling rate can be controlled by adjusting the proportion of each component

Products	Color（APHA）	viscosity_40℃（mm²/s）	Cloud point (1%water,℃)	Appearance （20℃）	Recommended Use
SDN-20	200	18000	75	Transparent viscous liquid	Carbon steel, aluminum alloy surface quenching, induction quenching
SDN-20-A	200	23000	75	Transparent viscous liquid	Long-life induction hardening, aluminum alloy
SDN-45	200	60000	75	Transparent viscous liquid	Carbon steel, alloy steel immersion quenching
SDN-105	200	110000	75	Transparent viscous liquid	Long life alloy steel
SDN-165 (50% aqueous solution)	100	2000	75	Transparent viscous liquid	Baptist quenched

High-molecular polymer provides excellent brightness of quenched workpiece.

Transparent viscous liquid,no need of heating, easy to use.

High flash point,longer life,low dosage,suitable for bright oil,speediness quenching oil special recommend to use in isothermal quenching oil.
