How We Helped a Brazilian Customer Overcome Copper Pyrithione Crystallization

Customer Background
Our client is a well-established chemical manufacturer in Brazil, relying on our Copper Pyrithione (SPT) for their production process.

Challenge
During recent production runs, two batches of Copper Pyrithione crystallized due to cold winter temperatures. This caused production difficulties and raw material losses, as the product stuck to containers. The client’s R&D team assessed the losses and requested a credit or discount on future orders.

Our Response
We recognized this crystallization issue, which has occurred before during colder seasons. To help, we recommended steam heating to effectively dissolve the crystals.

We provided clear, step-by-step guidance:

Open the IBC drum and pump the SPT into a heatable container.

Gently heat the product until crystals dissolve completely.

Pour the heated SPT back into the drum and stir thoroughly with a dedicated mixer.

We assured the client that if crystallization persists, the loss could be deducted from their next order.

Outcome
The client appreciated our swift support and practical solution, ensuring their production runs smoothly despite challenging conditions. This case highlights our commitment to excellent after-sales service and strong customer partnerships.

Client Feedback
