Using Process
Tool cleaning and maintenance
Tools and equipment must be cleaned and maintained immediately after use to avoid curing as the cured rubber is difficult to clean up. Please wipe off the surrounding rubber with cleaning paper or cloth, and then use hot water and detergent to remove it. If you use solvents for cleaning, please take personal precautions. Masks, gloves and face masks cannot be omitted. In addition, adequate air circulation and fire safety must also be paid attention to.

Skin protection before work and after washing hands |
Hand cream or lotion must be applied to form a protective film on the skin surface |
Materials on the skin
Wipe off the materials with a paper towel or facial tissue and then wash it off with warm water and non-alkaline soap. Do not use solvents to clean the skin to avoid allergies.
Spilled materials on the ground
Just use sand or sawdust to absorb the materials. You can also use industrial rags or industrial paper to wipe clean. Do not use solvents to pour on the ground and clean directly. There is a risk of fire.
First aid rules
If you are accidentally splashed with resin or hardener or mixture, please use an eye flusher to flush for 10-15 minutes and send to an emergency ophthalmologist. If accidentally splashed on other parts of the skin, please wipe it with facial tissue. Wipe off the materials, and then clean the surface of the skin with warm water and detergent until it is clean. And use hand cream or lotion to maintain the over-cleaned superficial skin. If you still feel unwell, please seek emergency medical attention.
Please pay special attention to the possible burns and overheated steam of opening the high-temperature oven, which can also harm personal safety. Suitable ventilation equipment can avoid work hazards and ensure the safety of operators.
