Use:
|
Water-based cross-linking agent is a water-based solvent-free emulsion poly-isocyanate, which can be used a lot of moderate PH value of polymer emulsion cross-linking agent, such as polyurethane, polyvinyl acetate, acrylic and synthetic rubber latex. This cross-linking can improve heat-resistant adhesive, water, plasticizer and solvent performance.

10-25 ℃ in the sealed original preservation, can be stably stored for 6 months. This product is moisture sensitive reaction with water to form carbon dioxide and insoluble urea. Therefore, containers shall at all times remain sealed condition. Should be avoided with the humidity, solvents, moisture and humidity in the reaction vessel. Pressure of carbon dioxide will increase, thereby increasing their risk.

Usage:
|
In order to ensure cross-linking agent can be fully dispersed in water-based adhesives should be used for mechanical agitation. Hand mixing to form homogeneous dispersions enough, especially when the dispersion of low viscosity adhesive to fully mixing becomes particularly important. Inadequate mixing easily formed in the adhesive gel particles.
Adding water-based crosslinker later, the two-component adhesive to be used up during its application. The duration of application of the polymer not only related to the content, but also with the other ingredients (such as resins, thickeners, plasticizers, etc.). Application period is over (usually for several hours), not always present gel state. Can be measured be reflected heat and water-resistance.
The amount of added water-based crosslinker weight of 100 copies of the binder dispersion of 3% -5% of the (polymer content of 40% -60%)

Safty Notice:
|
Pollution before removing the dangerous goods shall not be thrown off label. Poly-isocyanate products require special attention to the safety of its operation. The high sensitivity of guinea pig tests showed that the product easy to produce allergic skin. However, long-term use of aliphatic poly-isocyanate easy to experience and test results under conditions of use have indicated that their risk of skin allergies should be minimal. Shall comply with the safe operation of this product description. Its contents related to marking, transportation, storage, operations, product safety and ecology.
