Using Epoxy Coating For Custom Lapel Pins

Introduction

Epoxy is a popular choice for your custom lapel pins, renowned for its durability and aesthetic appeal. This clear resin coating enhances the look of pins while providing essential protection against environmental factors.

What is Epoxy?

Epoxy is a thermosetting polymer that consists of two components: resin and hardener. When mixed, they undergo a chemical reaction that transforms the liquid mixture into a solid, resilient coating. This process not only strengthens the soft enamel pins but also adds a glossy finish. Epoxy is normally provided by mixed cured of 2 kinds of gel, or commonly known as A gel, B gel. these 2 kinds of it are liquid,and mixed in proportion 3:1, then must to mixing 3-5 minutes, until the 2 gel completely mixed. No good mixed epoxy coatted on surface of lapel pins, and drying it, then epoxy color will be unevenness, seriously affecting product quality.

Benefits of Using Epoxy for Custom Lapel Pins

1. Durability
   • Epoxy provides a tough, protective layer that withstands wear and tear. It is resistant to scratches, UV light, and chemicals, making it ideal for items worn daily.
2. Aesthetic Enhancement
   • The glossy finish of epoxy enhances colors and designs, making pins visually appealing. It gives a professional look that can elevate the overall quality of the product.
3. Water and Stain Resistance
   • The coating prevents moisture and dirt from damaging the underlying metal, ensuring that pins remain in excellent condition over time.
4. Customization Options
   • Epoxy can be tinted with different colors or effects, allowing for creative and customized designs that cater to various preferences.

Application Process

The application of epoxy in pin making typically involves several steps:

1. Preparation
   • The pin’s surface is cleaned and prepped to ensure optimal adhesion.
2. Mixing
   • The resin and hardener are mixed in a specific ratio, usually 3:1, to achieve the desired consistency.
3. Application
   • The mixture is carefully applied to the pin, either by pouring or using a brush.
4. Curing
   • Pins are then baked at a controlled temperature (usually 80-90 degrees Celsius) for about an hour, allowing the epoxy to harden fully.
5. Finishing Touches
   • Once cured, the pins can be polished to enhance their shine further.

Challenges in Epoxy Application

While epoxy coating offers many advantages, it also presents challenges, especially with complex designs . Achieving an even coating without bubbles or imperfections requires skill and experience. Epoxy generally bake 80-90 degree, about 1 hour. only after a certain temperature and time, epoxy will be harden and resilient. Epoxy coatted products must be taken down from the fixture when it does not too hot, and too cooled. Because epoxy is soft when it too hot, too cooled it be harden. The workerman also have to be careful not to make face from too much force, so that the surface will not hurt.

Conclusion

Epoxy coating plays a vital role in lapel pin industry, combining functionality with beauty. Its ability to protect and enhance the visual appeal of pins makes it a preferred choice for manufacturers aiming to deliver high-quality products. Whether for promotional items or personal collections, epoxy-coated pins stand out for their durability and design potential.
