6 Our factory
SHANGHAI JUNBOND BUILDING MATERIAL CO., LTD Located in Shanghai, China.
Our company is a large group in the production of silicone sealants;
The main products are structural silicone sealant, stone silicone sealant, weather-resistant silicone sealant, two-component silicone sealant, and other products;
The factories are located in 6 different provinces in China, relying on raw material supply bases to produce professional silicone sealants.
Safety:
It has no toxicity after entirely cured. Avoid eye contact it when operating. If happened, rinse opened eye under running water for several minutes. During the curing process, sealant will release a small amount of organic molecules. Construction should ensure good ventilation. If necessary, take protective measures. Please keep out of reach of children.
