【Introduction】
Crosslinking agent JL-502 is a crosslinking agent. By mixing with PVC coating agent, it can quickly produce crosslinking reaction with resin at high temperature.
【Characteristics and Advantages】
(1) JL-502 can improve the adhesion between PVC coating and fabric, with low dosage, high initial adhesion, long-lasting effect;
(2)It can make the coating haveexcellent wear resistance and aging resistance.

【Dosage for reference】
Processing process:
Add the crosslinking agent JL-502 to the PVC coating agent at 3-8%, stir it evenly, apply it on the base cloth, and then dry it (drying temperature is generally 130-160℃) and plasticize it (plasticizing temperature is generally 170-220℃), and the oven time is generally 60-90s.
Note:
(1) After adding crosslinking agent, please use it within 1-4 hours.
(2)The fluidity of this product will deteriorate at low temperature in winter, and it will return to normal after mixing, without affecting the product quality.
