Product description

Product Features:

TSY series primers are two-component addition vulcanized primers. It can form an excellent bond between the coated substrate and the adhesive. Condensation and addition type adhesives can be matched with them. There are environmentally friendly and solvent-based adhesives to meet the needs of different users.

 

Ratio:

model

Proportion

TSY-7000 (main agent)

100

TSY-4000 (curing agent)

4-4.3

Measure according to the above ratio, and then dissolve and dilute with 4-5 times toluene (specific users can add toluene according to their own glue concentration), stir and mix well, sample and observe to confirm that it has been completely dissolved, the sampling laboratory test is qualified, and then Glue is applied on the machine.

 

Applications:

Various substrates such as textured paper, PET, PI, fiber, spunlace non-woven fabric, TPU, etc.

 

vulcanization:

Coat the prepared toluene solution of the primer evenly on the substrate according to the coating thickness requirements, then vulcanize at 130°C for 1-1.5 minutes, and then coat the silicone pressure-sensitive adhesive on it.

 

Precautions:

1. The TSY primer is an addition vulcanization type. During the entire glue dispensing and coating process, it is strictly forbidden to contact metals such as lead, cadmium, tin and peroxides to prevent poisoning and failure;

2. Shake the curing agent well before use, and then add it to the main agent. Because it will be stratified after being left for a long time, as long as it is shaken, it will not affect the use effect;

3. Use a clean container every time. Use toluene and other solvents to clean the recycle container thoroughly for next use;

4. It is recommended to use up the matched primer within 12 hours. The unused part should be sealed and stored in a clean container. When using it for the second time, it needs to be tested first, and then put into production;

5. The accuracy of the proportioning of the main agent and the curing agent and whether the mixing is uniform has a great impact on the vulcanization and performance. Wrong mixing ratio or uneven mixing will lead to non-vulcanization or incomplete vulcanization, which will affect the final performance;

6. After vulcanization, the physical properties are related to the ratio, coating thickness, and vulcanization temperature. It is recommended that users make appropriate adjustments according to their own process conditions and final performance requirements.
