Hydrophilic Crosslinker for Two-Component Systems

Specification

Suggested Application

KL-302 is suitable for hydrophilic resins, such as water-based acrylate resins, polyurethane resins, and synthetic rubber emulsion, and it favors to improve adhesion, tensile strength, and hardness of the cured resins.

Typical Application

In general, the dosage of KL-302 is about 3~5% of the total curing system (special cases can be added to 1~10%). Customers shall have a test according to their own needs to determine the optimized addition amount.

Mechanical agitation is necessary for a well-mixing effect.

After mixing, the coating systems should be used in its pot life, usually of several hours. However, due to the great differences lie in chemical composition among resin systems, customers should have a self-testing to ascertain the actual pot life.

Packaging & Storage

Available in25 Kgplastic drums, 4x5 Kgplastic drums, or specified packing requests of customers.

Place in cool and dry place with adequate ventilation.

KL-302 is very sensitive to moisture, and can easily react with water, leading to the formation of carbon dioxide and insoluble urea. Therefore, the packaging container must be well sealed to avoid the unexpected reaction derived from water of moisture, solvent, and wet container, etc. The crosslinker should be consumed within 6 months to achieve the best using effect.
