lLong pot life and excellent resistance.

lLINKER 9080 can effectively improve physical properties when used for coating.

lFree of heavy metals, formaldehyde, PAHs, PBBs, PBDEs and other restrictions.

Application:

lIt is used as a crosslinking agent for water-based systems such as acrylic and polyurethane, can improving the adhesion strength, waterproofing, wear resistance, scrub resistance, chemical resistance, and stacking properties of coatings.

lIt can be added to any polymer resin lotion with amino and hydroxyl groups to improve the strength and chemical resistance of the resin after drying and heat treatment.

lCustomers should test the applicable period according to their own process needs and compatible resin system. After addition of LINKER 9080, the ready-to-use mixture must be used within the pot life. It is generally recommended to use it within 3 hours.

This crosslinking agent is very sensitive to moisture and reacts with water to produce gases such as carbon dioxide and urea. Carbon dioxide can cause container pressure to rise, creating dangerous hazards.
