In knife coating, everything hinges on the rheology of the paste. Even a slight shift in viscosity can alter how it fuses, how it adheres to the rolls, and the final finish—and a seemingly minor change in the raw material can throw the whole process off balance. That's why, in this industry, the supplier's consistency is just as important as the quality of the additive.
For this application, we have available the additives needed by a textile coating converter: K71 and K76 PVC resins, plasticizers (DOTP, DOP, TOTM), BaZn and CaZn liquid stabilizers, internal lubricants for soybean paste and epoxidization, ready for shipment. partial lots from a national warehouse.
We work with two models: deliveries in smaller quantities when your formula or operation justifies it, and full container loads at a preferential price. We keep the material in stock and deliver it when your schedule requires it—something especially valuable in textile coatings, where Changing suppliers for a pre-calibrated paste can destabilize the fusion, adhesion, or finish.
PVC coating on a textile backing for tarpaulins, awnings, and tents. It requires good weather resistance and a plastisol that spreads evenly without trapping volatiles. Antimicrobial protection prevents mold and staining on products exposed to the elements.
Synthetic leather for upholstery, leather goods, and footwear. The top coat defines stain resistance and the permanence of the plasticizer; the textile backing provides dimensional stability.
High-wear, flexible part that combines mechanical strength with low-temperature flexibility. The selection of plasticizer and the paste density are crucial to prevent defects in thick parts.

Immediate availability in national warehouse. Critical additives for plastisol in stock for delivery in 24-72 hours within Mexico.
Partial lots or full container loads at preferential prices. Ideal when the additive is only a fraction of your pasta.
One-stop-shop for your plastisol. Paste resin, plasticizers, stabilizers, internal lubricants and ESBO from a single supplier; consolidate your traceability.
Batch-to-batch consistency. In blade coating, reproducibility is everything; we grade the material so that your paste does not change behavior between deliveries.
Backup in times of crisis. If your usual supplier experiences delays or changes specifications without notice, we can cover with qualified material in days, not months.
Coverage Mexico + Central and South America. Over 30 years in PVC additives.
In knife-cut textile coating, most defects do not come from "poor quality" of the additive, but from how each ingredient interacts with the rheology of the paste. These are the situations we see most frequently:
Switching between two plasticizers that appear equivalent—for example, DOP and DOTP—alters how the paste fuses and adheres to the rolls. It's not a problem with one product or the other; it's that the paste is calibrated for a specific rheology. RecommendationMaintain a constant plasticizer level; any changes must be calibrated on a scale before production, readjusting the internal lubrication to restore the working viscosity. We can help you calibrate it.
When changing stabilizers, pinholes may appear: gases that are trapped in the paste and do not escape during melting. RecommendationIn tarpaulins and mud flaps, the low-density stabilizer helps the paste release volatiles and prevents the defect; changing it to a denser one can reintroduce it. Contact us to choose the right one.
When layers with different concentrations of plasticizer come into contact, the plasticizer migrates and marks or deformation appear. RecommendationUse a plasticizer with lower diffusibility in the layer that will be in contact with finishes or other parts. We'll advise you on the best option.
