Silicone hardener, also known as silicone curing agent or catalyst, the main role is to promote the cross-linking reaction of silicone, so that the silicone from the liquid state into a solid state, so as to achieve the purpose of fixing the printing pattern and increase the durability of the product. It is usually a special chemical additive, which has a wide variety of types and different properties.
Printing process
Ensure that the working area is clean and tidy, and prepare the required materials and tools such as silicone, Silicone hardener, screen plate, squeegee and substrate.
According to the requirements of the product and working conditions, mix the silicone with the appropriate amount of silicone hardener. Pay attention to add the exact amount, otherwise it will affect the curing effect and product quality.
Choose a suitable screen plate, clean and dry. Apply the blended silica gel evenly to the pattern part of the screen plate.
Place the screen plate on the substrate and use a squeegee to scrape the silicone from the non-patterned part of the screen plate, so that the silica gel is transferred to the substrate through the mesh of the patterned part.
The printed product is placed in a suitable environment for curing. The curing time, temperature and humidity conditions should be adjusted according to the silicone instructions.
After curing, necessary post-processing, such as cleaning, trimming, etc., is carried out to obtain the final product that meets the requirements.
FAQ
Q1: What is the function of it?
A1: The main function is to promote the curing of the silicone, so that the silicone from liquid to solid, and increase the durability and stability of the product.
Q2: How to choose the right silicone hardener?
A2: You need to consider the type of silicone, printing requirements, working environment and other factors. It is recommended to communicate with silicone suppliers or technical experts for professional advice.
Q3: What are the effects of adding too much or too little?
A3: Adding too much may cause the silicone to cure too quickly, affecting the printing effect; adding too little may cause the silicone to cure incompletely, affecting the durability and stability of the product.
