Usage:

The best addition method: First, mix TL-05 with water or organic solvent in a 1:1 ratio and stir evenly by hand. Rejoin

In the emulsion system, it can be used by manually stirring.

Suggested end use:

Water resistance, alcohol resistance, and durability can be improved in water-based parquet flooring paint

Detergent, chemical resistance, and wear resistance.

Water resistance, alcohol resistance, and anti adhesion can be improved in water-based industrial paints.

In ethylene based coatings, the migration of plasticizers can be reduced and the resistance can be improved Dirtiness.

Improve its wear resistance in water-based mud sealant.

It can generally improve the adhesion of water-based systems on non porous substrates.

Improve the resistance of solvent based polymers.

Printing Ink Industry: Improve the water resistance and detergent resistance of water-based acrylic and polyurethane inks.

Clothing printing industry: Improve the water resistance, adhesive resistance, and high temperature resistance of water-based acrylic and polyurethane printing coatings.

Pressure sensitive adhesive industry:

Improve the adhesion of water-based acrylic pressure-sensitive adhesive.

Leather finishing agent industry: improving the adhesion, water resistance, and washing resistance of water-based acrylic and polyurethane leather coatings

Chemical resistance and high temperature resistance.

Waterborne coatings: Improve the hardness, water resistance, alcohol resistance, and anti adhesion of waterborne acrylic and polyurethane industrial coatings.

Textile coating industry: Improve the weather resistance, water resistance, oil resistance, and adhesive resistance of water-based acrylic and polyurethane coatings.

Suggested formula: Additives

TL-05 is a trifunctional crosslinking agent that can undergo crosslinking reaction with the hydroxyl groups of polymers (equivalent number 166)

In most cases, the best improvement effect can be achieved by reacting each equivalent of hydroxyl group with 0.6 equivalent of it, but there are some

The system requires an equivalent amount of crosslinking agent to react with it.

In general, crosslinking all acrylic or polyurethane dispersions requires 2% or 3% TL-05(by weight)

Tl-05 should be added before the use of varnish, coatings, and inks. Due to its excellent miscibility, it can be manually stirred

Can be used. The best addition method is to mix TL-05 with water in a 1:1 ratio before adding it to the system.

Adding TL-05 to water-based formulas will slowly hydrolyze, and the mixture should be used up within 3-5 days. But hydrolysates and polymer emulsions

There are no adverse effects on the film, and adding a certain amount of it may restore the crosslinking reaction.

It can improve the overall performance of solvent based polymer systems, but it must be used up within 1 day as the viscosity of the system tends to decrease

Elevate and potentially form gel.


Safety and toxicity:

It is limited to industrial production, with industrial producers such as formulators, professionals, and trained workers, such as

If the equipment used is safe and operated according to the instructions, it can be ensured that the product can be used safely.

It has no government approval for use in food packaging containers that do not come into direct contact with coatings and inks.

Instructions for use:

Handle with care and avoid direct contact with skin and eyes. When using spray painting, special attention should be paid to inhalation through the mouth and nose, and a dedicated mask should be worn

When using it, it is best to operate under the conditions of ventilation and protective devices to prevent inhalation of volatile gases.

Storage method:

Store in a cool, ventilated, and dry place. If the storage temperature is too high and the time is too long, discoloration, gel formation, and damage may occur

Damaged or deteriorated.
