　　In the small home appliance industry, we provide reliable high temperature resistant products for a wide range of products including electric irons, microwave ovens, hair dryers, blenders, juicers, etc. Our product applications include thread locking, high temperature resistant flat sealing and rapid bonding. Thread locking provides high temperature resistance up to 200℃ anaerobic type thread locking adhesive, to provide customers with reliable anti-loosening products.
High temperature resistant flat seal provides single and two component silicone sealant, the highest high temperature resistance up to 350℃.
　　Rapid bonding provides a comprehensive range of instant dry adhesive products, transparent and beautiful, a variety of viscosity options, the base material is very wide application, high temperature resistance up to 120℃, perfect to meet your application needs. Case Study of UV Adhesive for Camera:
　　The customer is an optical coating manufacturer specializing in the development and production of infrared cutoff filters, protective glass, low-pass filters for mobile phone cameras and digital cameras. We mainly produce multi-layer coated lenses, protective glass, mirror base assembly, etc. The coated lenses include 10000K/month infrared cut-off filter, low pass filter (OLPF), multi-layer anti-reflection film, reflection film and other special coatings. Case application: The product used in this case is camera, and the material is glass lens and plastic (material is PP+ glass fiber).
　　Performance requirements: It is not required to overflow glue (viscosity range is 2000~3000cps, too high is not good for dispensing, too thin will overflow glue), the glue of the glue, the strength is required to be above 3mpa. After finishing the ring test (including high temperature and humidity, hot and cold cycle), the adhesive force test will be made again at 2.5mpa; Additional assembly test (this lens on the phone) will be free fall test (1M high free fall) after the phone is assembled, requiring the lens not to separate.
　　Existing problems: no less than 5 kinds of glue have been tried, including Loctite, but the bonding strength fails to meet the requirements; Measured bonding strength below 2, some measured bonding strength between 2.5~3.0, occasionally can pass 3; However, Samsung, its customer, requires 3 or more to be OK.
