Jowat 93120 Flushing Agent (NOT PUR)

Jowat 93120 Flushing Agent (NOT PUR) – Frequently Asked Questions

What is Jowat 93120 Flushing Agent?

Jowat 93120 Flushing Agent is a specialized solvent-based cleaning fluid designed to flush adhesive application systems, glue pots, and adhesive feed lines. It is used to remove residual adhesive build-up — particularly from non-PUR adhesives — to keep adhesive equipment clean and operating reliably.

Is Jowat 93120 a PUR adhesive?

No. Jowat 93120 Flushing Agent is expressly not a polyurethane reactive (PUR) adhesive. It is a cleaning/maintenance product used to remove adhesive residue and prevent clogs in adhesive distribution systems.

What types of adhesives is Jowat 93120 used with?

This flushing agent is used with non-PUR adhesive systems (e.g., EVA, APAO, or other thermoplastic hotmelts) to clean glue pots, application lines, nozzles, and surrounding components to ensure smooth adhesive flow and minimize maintenance downtime.

Why use a flushing agent like Jowat 93120?

Adhesive build-up in glue pots, hoses, and application heads can cause inconsistent adhesive application, reduced bond quality, clogs, and machine downtime. Using a flushing agent regularly helps maintain consistent adhesive viscosity and keeps systems clean.

How does Jowat 93120 work?

Jowat 93120 dissolves typical thermoplastic adhesive residues within application systems. It flushes out hardened or semi-hardened adhesive residues that can accumulate in glue pots, hoses, and dispensing components, restoring consistent flow and reducing service issues.

When should I use Jowat 93120?

Use it during scheduled maintenance, adhesive changes, or when adhesive flow becomes inconsistent due to build-up. It is also recommended when switching between adhesive types (excluding PUR) that are compatible with the flushing agent.

Is Jowat 93120 compatible with PUR hotmelt systems?

Because PUR adhesives cure chemically and cross-link within the system, standard flushing agents like 93120 are not suitable for PUR clean-up. PUR systems require specialized PUR purge products and procedures. Always consult the machine manufacturer and adhesive supplier before flushing any PUR equipment.

How do I apply the flushing agent?

Follow your machine manufacturer’s instructions. Typically, the system is heated to adhesive operating temperature, then the flushing agent is introduced to the pot and circulated through the lines and heads to dissolve and carry out residual material. Always follow health and safety guidelines when handling solvents.

What are the benefits of regular flushing?

• Reduces adhesive buildup in glue pots, hoses, and nozzles • Improves adhesive flow consistency • Reduces machine downtime and maintenance interventions • Extends life of application components and heaters

Is the flushing agent hazardous?

Jowat 93120 is a chemical solvent. Refer to the Safety Data Sheet (SDS) for handling instructions, protective equipment requirements, and first-aid measures. Use with adequate ventilation and appropriate personal protective equipment (PPE).

Can I flush while the system is cold?

Generally no. Flushing performance is best when the system is at adhesive operating temperature, as residues soften and dissolve more effectively. Always follow machine and adhesive supplier guidelines.

How often should I flush my adhesive system?

Frequency depends on adhesive type, usage levels, and machine design. As a rule of thumb: at adhesive changeovers, signs of buildup, or at routine maintenance intervals recommended by your equipment OEM or adhesive supplier.

Does Jowat 93120 remove carbonized adhesive?

It assists with softening and removing residual build-up, but heavy carbonization may require mechanical cleaning alongside solvent flushing for complete removal.

Can flushing agent affect machine seals or hoses?

Flushing solvents can interact with certain elastomers or seal materials. Always confirm compatibility with your machine manufacturer and review the product SDS before use.

Do I need a special flushing kit to use Jowat 93120?

Many adhesive systems have integrated purge/flush capabilities. If not, a dedicated flushing kit or adapter may be recommended to safely circulate the solvent through all adhesive pathways.

Can flushing agent improve adhesive quality?

Yes. By eliminating residual blockages and build-up, flushing helps maintain consistent adhesive delivery and more reliable bond performance for non-PUR adhesive applications.

How does this product differ from adhesive purge sticks?

Adhesive purge sticks are a physical method of clearing molten adhesive, whereas Jowat 93120 is a chemical solvent that dissolves adhesive residues. Both can be part of a maintenance strategy depending on machine design.

Is Jowat 93120 suitable for pneumatic adhesive systems?

Yes, when used according to manufacturer instructions and compatible with the machine’s components. Always check for seal and component compatibility before application.

What size and packaging does Jowat 93120 come in?

Packaging options vary by distributor but commonly include bottles or drums sized for shop-level cleaning and maintenance. Contact your supplier for available options and volumes.

Why choose Jowat flushing products?

Jowat is a global adhesive and application-support supplier with flushing products designed to complement adhesive performance and machine uptime. Flush agents like 93120 help maintain consistent adhesive application and equipment reliability in non-PUR systems.
