【DESCRIPTION】

YL-WB9500 is an active closed hydrophilic aliphatic polyisocyanate based on hexamethylene

diisocyanate; It can be used as an additive of water-based baking system and has the

characteristics of low temperature unsealing.

【COMPATIBILITY】

YL-WB9500 can be diluted with esters, ether esters, ketones and other solvents, and can also

be diluted with water. The diluted solution should always be tested for compatibility and

stability.

Appearance Water white to yellowish transparent liquid

Solid Content /% 70.0±2.0

Block isocyanate content 6.5-7.0

Viscosity (cp. 25℃) 500-1000

PRECAUTIONS FOR STORAGE (USE)

Because YL-WB9500 has a certain hydrophilicity, it can be easily dispersed in water under

common commercial shear force. It is a curing agent suitable for water-diluting single

component polyurethane baking system, which helps to improve the hardness, adhesion,

water resistance and chemical resistance of the coating after film formation.

The crosslinking effect of YL-WB9500 is affected by the baking temperature and the type of

coreactant. Under normal circumstances, when the baking temperature is greater than 90℃,

the blocking isocyanate will be released and the crosslinking reaction will begin; The

recommended baking temperature is 100℃, and the baking time should be reduced with the

increase of baking temperature.
