Nitrile-coated gloves are widely used. There are various coatings for their surfaces. Historically, smooth nitrile coating was introduced earlier than foam nitrile and sandy nitrile finish finishes. The smooth coating process offers excellent impermeability and good chemical resistance. It is used in many industries. This article provides a quick overview of the process and key features of smooth-coated gloves!
Smooth-Finish Coating Process for Nitrile-Coated Gloves
There are several steps involved in the smooth-finish coating process for coated gloves, and each step requires careful attention. The specific processing steps are as follows:
- Place the knitted glove liner over the former. Check that there are no wrinkles, especially around the fingers and seams. Preheat the former to approximately 45–55°C.
- Prepare the nitrile dipping compound. Prepare the nitrile latex compound according to production requirements. Add accelerators, activators (zinc oxide), sulfur, and pigments (for custom colors, etc.) according to the formula ratios.
Note: The compound should be vacuum-degassed before use. Key parameters such as viscosity and solids content should be closely monitored. - Coagulant Treatment: To promote uniform coating formation, the glove must be immersed in a coagulant solution before the nitrile coating dip. This creates a reactive layer on the liner surface, allowing the nitrile compound to gel and adhere evenly.
- Immerse the former, with the glove liner in place, into the specially formulated coagulant solution. To achieve a smooth surface, carefully control the dipping speed, angle, and withdrawal rate.
- Pre-drying: The gloves are placed in a tunnel oven, typically at 100–130°C (depending on line settings). This step helps set the coating before further processing.
- Leaching / Rinsing: The gloves are washed with warm or hot water to remove residual coagulant, unreacted chemicals, and impurities.
Characteristics of the Smooth-Finish Coating Process for Gloves
Gloves produced using the smooth-finish coating process feature a smooth and even surface. Their common characteristics are as follows:
- Chemical resistance
- Good resistance to liquid penetration
- Good fit and tactile sensitivity
The smooth coating process is suitable for precision manufacturing tasks. It offers good dexterity and tactile feedback. Additionally, it is highly suitable for applications requiring a clean working environment. Smooth coatings are generally low-lint and suitable for clean working areas when properly manufactured., ensuring a clean environment. It is commonly used in tasks such as electronics assembly and small-parts handling.
M-tide offers mature smooth-finish coating expertise.
M-tide has specialized in the R&D and production of work gloves for over 10 years. We have established experience in smooth-finish coating production. Every stage of the manufacturing process strictly adheres to regulatory standards and undergoes rigorous inspection and testing. When selecting work gloves with coatings, you should first determine the primary type of protection required. such as abrasion resistance, cut resistance, or oil resistance. Next, assess the work environment—whether it is dry, oily, or a cleanroom environment requiring precision-handling gloves.
In addition to smooth finishes, we also offer micro-foam, sandy, and ultra-fine foam surface technologies. We provide glove solutions tailored to your application needs. If you would like to learn more, please feel free to contact us!
