Hunan develops a new type of elastic epoxy adhesive

Not long ago, a new generation of flexible epoxy adhesives developed by Changsha High-tech Enterprise Co., Ltd., a new high-tech enterprise in Hunan Province, was identified as a high-tech product in Hunan Province.
The company relies on the strength of the Changsha Design and Research Institute of China National Bluestar (Group) Corporation (formerly the Changsha Design and Research Institute of the Ministry of Chemical Industry) to bring into play the advantages of research and development, promotion and application, and production and management. The field pursues with great concentration and finally succeeds. The company's new type of elastic epoxy adhesive includes a total of seven major categories: new types of flexible epoxy adhesives, room-temperature curing flexible epoxy adhesives, plastic drop hard plastic adhesives, drop plastic crystal soft adhesives, grinding wheel special adhesives, grinding wheel adhesives Special adhesives for grinding wheels.
Among them, the new type of elastic epoxy adhesive (BS-2101A/B) has low viscosity, good operation performance, simple glue distribution, easy use, low heat release and long service life; after curing, the adhesive layer has high flexibility, high expansion rate, and impact resistance Excellent performance, low stress on glue parts; insensitive to water, carbon dioxide, no amine turbidity, good surface gloss of cured product; large proportion of curing agent, small influence of weighing error; low toxicity and low irritation, to operators Safe and non-destructive; with detachability (removal of plastics if required under heating conditions above 80°C), by adjusting the formula to meet the special needs of optical instruments. It is mainly used for the bonding of dissimilar materials with different thermal expansion coefficients and soft materials, such as metal to plastic, metal to glass, ceramics, filling of bridge expansion joints, and bonding of plastics (such as polyvinyl chloride, organic glass, etc.) Concrete repairs, tackings, and bonding of some optical components and sensing elements that require low stress.
Room-curing flexible epoxy adhesive (BS-2105A/B) has low viscosity, good operability, suitable for large-area coating, low toxicity and low irritation, and is safe to the operator; after curing, the adhesive layer is light-colored transparent and has a glossy surface Good; adhesive layer has good flexibility, good stress on adhesive parts, excellent impact resistance, excellent adhesiveness, and suitable for bonding in various conditions. It is mainly used for dissimilar materials with large differences in thermal expansion coefficient, especially for bonding of soft materials such as metal to plastic, metal to foam, metal to glass and ceramics, repair of buildings and coagulation components, and caulking; It requires bonding and assembly of electronic components and sensor elements with low stress.
In another development, the company also produces hard plastic drop-type adhesives, plastic drops of plastic soft adhesives, special adhesives for grinding wheels, special adhesives for grinding wheels, and other products, which are well received by users.
