Specification

Physicochemical property and technical index:

Appearance	Colorless to slightly yellow liquid
Viscosity	100mPa. s (20 ºC)
PH	9-12
Solid content	40% (water based)

Applications

Application area and performance:

DB302 is a polycarbodiimide water-based anti hydrolysis crosslinking agent, which can significantly improve the hydrolysis resistance, chemical resistance, abrasion resistance and scratch resistance of the resin when used in water-based acrylic lotion or polyurethane dispersion; At the same time, it can enhance the adhesion of specific substrates. It can also be applied to industrial coatings (metal, film, etc.), woodworking coatings, shoe adhesives, leather, and other fields. And it is non-toxic and VOC free, and can replace nitrogen and propylene.
 

Typical application methods:

DB302 is used as an anti hydrolysis crosslinking agent for waterborne polyurethane or waterborne acrylic resin, its dosage and usage are as follows:
In the water-based polyurethane system, the addition amount is 4-7% of the resin content in the solution, and it is recommended that the drying temperature be higher than 50 ºC;
In the water-based acrylic acid system, it reacts with carboxyl groups with an addition amount of 3-6%, and it is recommended to be added into before curing.
 

Package and Storage

Packaging specification:

10KG, 18KG, 25KG galvanized drums or plastic drums.

Storage:

It is advisable to store in a dark, dry, and sealed condition at a storage temperature of 5-35 ºC, and pay attention to antifreeze.
