Dip Coating

Cold Dipping Plastisols

The cold dipping process is used when the substrate can not withstand the heat involved in the preheat process, or if the substrate can not build enough heat to get the desired thickness. Products made with the cold dipping process include supported gloves, coated paper clips, etc.


1. The part to be coated must be clean and free of dirt.

2. Fasten a suspension system to the item being coated.

3. Immerse the item to be coated at a rate of 1/2" every 1-2 seconds. Use a smooth feed rate.

4. Hold the position in the plastisol for 5-10 seconds or until the plastisol levels around the part.

5. Withdraw the part at the same rate as immersion. If properly withdrawn there should be no dripping of plastisol and no waviness on the part. Avoid any sudden jarring of the part to avoid disturbing the plastisol coating.

6. Suspend the part in an oven set between 365° and 400°F until it is cured. The cure time will depend on the oven temperature, mass of the part, and complexity of the part.   Remember that most plastisols will cure between the temperature of 350° and 360°F .

7. If a thicker coat is desired, repeat the procedure starting with step 3. Otherwise cool with water or air.

Note: Cold dips can also be sprayed if dipping is not applicable.
