Proper care keeps your gear ready for every project. Using DOP plasticizer when storing your spray foam equipment prevents damage, preserves performance, and saves money over time. This is especially true for complex systems like Graco Reactors, heated hoses, transfer pumps, spray guns, and coating sprayers. With the right storage practices, DOP plasticizer becomes a core part of protecting your entire setup.
How DOP Plasticizer Works
When equipment sits idle, parts like seals, o-rings, hoses, and gun components can dry out or stiffen. DOP plasticizer forms a thin protective film over these internal parts. It seeps into small crevices, conditions sealing surfaces, and lubricates moving parts. This prevents chemical residue from hardening, reduces brittleness, and keeps your spray foam equipment flexible. The result is smoother startup and fewer issues when you bring your system back online.
Benefits of Using DOP Plasticizer
- Keeps seals and gaskets in Graco Reactors pliable and leak-free
- Prevents cracking in heated hoses, especially in high-pressure lines
- Protects transfer pumps from corrosion and residue buildup
- Ensures spray guns function without sticking or clogging
- Reduces downtime by cutting back on repairs and replacements
- Extends the service life of your spray foam equipment
Graco Equipment & Why DOP Plasticizer is Important
Spray Foam Systems carries a wide range of Graco equipment that benefits greatly from proper storage and conditioning.
- Reactors: From entry-level E-10 and E-20 to advanced Reactor 3 series, these machines rely on precision seals and heated components. DOP plasticizer helps keep them flexible.
- Heated Hoses: Graco hoses with internal or external heating can become brittle in storage. A conditioning flush with DOP plasticizer prevents cracking.
- Transfer Pumps: Both pneumatic and electric pumps risk buildup from leftover foam or coating materials. DOP plasticizer coats the internals to prevent damage.
- Spray Guns & Coating Sprayers: Small passages in Graco guns and sprayers can clog if material cures inside. A rinse with DOP plasticizer keeps them clean and ready.
How to Use DOP Plasticizer for Storage
- Flush your spray foam equipment with an approved cleaner.
- Introduce DOP plasticizer into the system—hoses, pumps, and guns should all be filled.
- Trigger the gun to move the solution through internal chambers.
- Seal off hose ends and cover fittings to prevent contamination.
- Before your next job, flush out DOP plasticizer if required by the manufacturer.
Safety and PPE
Whenever you handle cleaners or DOP plasticizer, PPE is essential:
- Wear chemical-resistant gloves
- Use safety goggles or a face shield
- Wear coveralls or protective clothing
- Use a respirator if ventilation is poor
- Always follow SDS and manufacturer guidelines
FAQs
1. Can I leave DOP plasticizer inside my spray foam equipment long term?
It’s safe during storage, but before applying foam or coatings again, flush the system if the manufacturer recommends it.
2. Is DOP plasticizer compatible with all Graco models?
Yes. DOP plasticizer works across all major Graco Reactors, hoses, pumps, and spray guns without damaging seals or components.
3. How often should I use DOP plasticizer on spray foam equipment?
Apply it any time your system will be idle for more than a few days, or after working in extreme temperatures.
