Dielectric paste JZ3041

     LEED JZ3041 is a dielectric paste designed for 304-type austenitic steels. It has excellent insulating property, small distortion, strong adhesive power, good printing performance and toxic element free up to European RoHS environmental regulation. LEED dielectric paste JZ3041 and LEED resistive paste DZ 430 XXXX, compatible perfectly with LEED DT 430X conductor paste, are key materials for thick film resistors and heating elements. It is recommended the lustration grade of appliance and circumstance should be more than one thousand degree.

Notice of usage and storage

1£®The lustration grade of appliance and circumstance should be ten thousand degree before screening and drying 

2£®Stainless steel substrate should get rid of nick and burr on surface.

3£®The operator must wear glove or fingertip to preventing from fingerprint pollution.

4£®The used material should be collected and sealed up alone. Don¡¯t mix with other untapped material.

5£®Before using the paste, it is essential to take out of from icebox or icehouse firstly and place it at about 25¡æ beyond 12 hours. Keep stir it slowly and fully till the composition of this paste is uniform.

6£®It should be guarantee that the room temperature and appliance temperature remains 26¡À2¡æ during printing.

7£®Paste material placed on the screen should be moderate when making screen-printing and added regularly.

8£®Dilute the paste moderately to recover the printing performance.

9£®The storage temperature is recommended between 5 and 10¡æ. The shelf time is commonly 6 months.
