Packaging and storage

5KG, 25KG, this product in dry, low temperature, closed, away from light (including ultraviolet and visible light) 

place storage, be sure to avoid contact with acids and oxidants, avoid freezing or high temperature. 

From the date of production, the storage period of the product under the original packaging conditions is 12 months; 

Non-flammable and explosive products, but there is a certain corrosiveness, belonging to the general danger.

Purpose

Proposed use:

1. Improve the adhesion of water-based pressure sensitive adhesive and adhesive, stability, speed up the curing time, good high temperature resistance, enhanced adhesion ability, and improve the later viscosity

2. Improve the water resistance, washing resistance, chemical resistance and high temperature resistance of the leather coating; Acceleration of curing time

3. In water-based parquet flooring varnish, water-based plastic paint and water-based metal paint, it can improve its water resistance, alcohol resistance, washing resistance, chemical resistance and wear resistance

4. In water-based industrial wood paint can improve its water resistance, alcohol resistance, anti-viscosity;

5. It can generally improve the adhesion of the water-based system on the non-porous substrate

6 Improve the water resistance and washing resistance of water-based printing ink; Avoid deinking when printing ink

7. Suitable for poly-cotton, cotton and medium and long fiber pad dyeing process

8. Improve the water resistance, viscosity resistance and high temperature resistance of the water-based printing coating

Usage method

In the use of pressure sensitive adhesives and adhesives, it is usually 1-3% of the solid content of the emulsion, and the pH value of the emulsion is 8.0 to 9.5, and it is best to use it in acidic media.

This product is mainly cross-linked with the carboxyl group in the emulsion, generally used at room temperature, and the baking effect is better at 50 ~ 80℃. Customers should test and determine according to their own process needs.

This product is a two-component crosslinking agent, should be added in advance, the best adding method is the crosslinking agent and water according to 1:1 ratio of miscible, and then immediately added to the system to stir evenly.

Once added to the system, it is recommended to use within 12 hours, otherwise it will form a certain gel phenomenon.

Before the use of varnish, paint and ink, because of its excellent miscibility, it can be stirred by hand, the best method is: first the crosslinking agent and water 1:1 miscibility and then add to the system.

It is best for customers to test their own application period according to the actual use temperature and emulsion system. At the same time, this product has a slightly irritating ammonia smell, should be handled carefully and avoid direct contact with the skin and eyes, as far as possible in a ventilated environment. Special attention should be paid to oral and nasal inhalation when spraying, and special masks, gloves and protective clothing should be worn.
