Industrial adhesive is an application classification of adhesives, which is a technology used in industry to connect surfaces of homogeneous or heterogeneous objects together with adhesives. Adhesives have the characteristics of continuous stress distribution, light weight, or sealing, and mostly low process temperature.
& nbsp; & nbsp; Industrial adhesive - how to remove the fixed device locked by thread locking adhesive< br />
& nbsp; & nbsp; It must be heated, and if the heating temperature exceeds 230 ℃, it can be separated. Do not use manual tools to remove the fixing device< br />
& nbsp; & nbsp; Can industrial adhesive stick my workpiece for 5, 10, 20 years< br />
& nbsp; & nbsp; Testing the durability of adhesives is a difficult task, and certain methods can help test the service life of adhesives to determine the actual time when the workpiece can be adhered, such as high temperature, aging, and high humidity. The most accurate method to determine the bonding time of a workpiece is to allow the workpiece to age over a certain period of time. The best way to estimate the bonding time is to compare the bonding life of a new product with a product that already has a known service life and performance ratio in aging testing, in order to evaluate the bonding life of the new product. The longer the requirement for bonding life of the product, the more important the aging detection of the product becomes.

& nbsp; & nbsp; How to deal with the water vapor and odor emitted by fast drying adhesives in industrial adhesives< br />
& nbsp; & nbsp; The water vapor and odor emitted by the quick drying adhesive powder are irritating, so workers should not be exposed to them for a long time. Usually& ldquo; Low volatility; Or“ Low whitening; It can control this irritating odor. It is necessary to install ventilation facilities and have workers wear masks< br />
& nbsp; & nbsp; Industrial adhesive - When using fast drying adhesive, white mist is found in the bonding area. Is it harmful? How to eliminate it< br />
& nbsp; & nbsp; This phenomenon is commonly referred to as“ Whitening” Or“ Frosting”, Appears during the curing process with quick drying adhesive. Whitening usually occurs in the summer when humidity is highest, and it can also cause strong curing reactions when excessive accelerator is used. In some cases, incomplete curing of the product by the user before assembly in a closed area can prevent water vapor from evaporating< br />
& nbsp; & nbsp; Industrial adhesives - Does cold temperature cause catalyst crystallization? How can I use it< br />
& nbsp; & nbsp; Heat it to 45-65 ℃ until the catalyst used dissolves, mix evenly, and cool it to 35 ℃ before use< br />
& nbsp; & nbsp; Industrial adhesives - how to choose suitable shaping coating materials< br />
& nbsp; & nbsp; Mainly consider the following factors:< br />
& nbsp; & nbsp; 1. The protective performance and reliability of the board surface and components in harsh environments, such as temperature range, pressure resistance, etc< br />
& nbsp; & nbsp; 2. The equipment for applying glue and the volume of the surface to be coated< br />
& nbsp; & nbsp; 3. Environmental and worker safety factors< br />
& nbsp; & nbsp; 4. Cost and configuration< br />
& nbsp; & nbsp; 5. Repair indicators
& nbsp; & nbsp; How many methods are there for applying industrial adhesive coating materials< br />
& nbsp; & nbsp; The four most commonly used methods are spraying and impregnationBrush coating Flow coating (pouring coating)< br />
& nbsp; & nbsp; How long does it take for industrial adhesives - anaerobic adhesives to cure< br />
& nbsp; & nbsp; As the name suggests, anaerobic adhesive only undergoes chemical reactions when it is not exposed to air. The typical curing time is a few minutes to over ten minutes, and the curing rate varies depending on the material and primer used. Heating can accelerate the curing speed< br />
& nbsp; & nbsp; Industrial adhesive - why only half a bottle of anaerobic adhesive< br />
& nbsp; & nbsp; Prevent anaerobic adhesive from solidifying due to lack of oxygen< br />
& nbsp; & nbsp; Do I need to use a primer for industrial adhesive - cured anaerobic adhesive< br />
& nbsp; & nbsp; The vast majority of metal surfaces do not require a primer. Primer is recommended for non-metallic surfaces with anaerobic adhesive to accelerate curing.

& nbsp; & nbsp; How long does it take for industrial adhesives to work on bonded components< br />
& nbsp; & nbsp; Depending on the adhesive and substrate, curing the thread locking adhesive takes 15-20 minutes and can withstand vibration for one hour. Rapid dissolution usually takes only a few seconds< br />
& nbsp; & nbsp; When should I use a primer or surface promoter for industrial adhesives< br />
& nbsp; & nbsp; Processing low surface energy active substrates, such as plastics, typically requires enhanced adhesion to achieve sufficient bonding strength. The choice of primer model depends on the specific application< br />
& nbsp; & nbsp; Do industrial adhesives - primers need to be used on both sides< br />
& nbsp; & nbsp; In most cases, only the side with poor adhesive strength needs to be coated. If a very fast curing time is required or the gap in the bonding area needs to have a gap greater than 0.15, double-sided coating is usually needed. When using primer, it is best to use less< br />
& nbsp; & nbsp; Industrial Adhesives - What preparations need to be made on the surface before using adhesives< br />
& nbsp; & nbsp; If there is a small amount of oil on the surface, thread locking adhesive and sealant can be used without surface treatment. To achieve sufficient bonding effect, it is necessary to remove the thick film of lubricating grease and pollutants. For building adhesives and instant adhesives, the acceptance of the processed surface must be determined through testing. Generally speaking, the processing surface with the lowest level of complexity is applied by the end user< br />
& nbsp; & nbsp; Will refrigeration extend the shelf life of industrial adhesives< br />
& nbsp; & nbsp; Refrigeration can extend the shelf life of quick drying glue before it is opened. Extending the shelf life of anaerobic adhesive, the effect of refrigeration is not significant. Please refer to the storage conditions on the product packaging label for specific details< br />
& nbsp; & nbsp; What is the shelf life of industrial adhesives< br />
& nbsp; & nbsp; It refers to the time from the date of manufacture to the expiration of the product. The shelf life of different products and models varies. For more information, please contact us.

& nbsp; & nbsp; How much industrial adhesive do I need< br />
& nbsp; & nbsp; Just fill in the adhesive area. Excess glue will be a waste and will overflow, making it difficult to clean. Automatic glue application equipment can control the continuous use of adhesive on the production line. How many drops are there in each tube, bottle, liter, and pound? It depends on the rate of liquid flow< br />
& nbsp; & nbsp; How to accelerate the curing speed of silicone RTV sealant in industrial adhesives< br />
& nbsp; & nbsp; The curing speed of adhesive cured at room temperature depends on the changes in room temperature and moisture. The higher the temperature, the greater the humidity, and the faster the curing speed. Curing occurs from the surface inward. Within approximately 24 hours, the 2MM thick part will turn into a solid rubber. The thicker the sealed part, the longer the curing time. Proper heating can shorten the curing time< br />
& nbsp; & nbsp; Industrial adhesive - can silicone be used on paint< br />
& nbsp; & nbsp; Most adhesives can be used on dry paint surfaces, but cannot be painted on adhesive surfaces< br />
& nbsp; & nbsp; What does Industrial Adhesive RTV mean< br />
& nbsp; & nbsp; RTV stands for Room Temperature Vulcanization, which means curing at room temperature< br />
& nbsp; & nbsp; Can industrial adhesives change their adhesive strength or other properties for suitable applications< br />
& nbsp; & nbsp; There are many adhesives with different bonding strengths and these products can meet many requirements< br />
& nbsp; & nbsp; Do industrial adhesives have conductive adhesives< br />
& nbsp; & nbsp; Industrial adhesives have both thermal and electrical conductivity< br />
& nbsp; & nbsp; What is the difference between industrial adhesives - pouring and packaging< br />
& nbsp; & nbsp; Watering refers to embedding an electronic component in a container containing insulating or protective materials. And encapsulation is a more commonly used term, referring to covering, covering, or protecting as if placed in a capsule.

& nbsp; & nbsp; Industrial Adhesive - How to prevent glue from flowing out of the bonding area< br />
& nbsp; & nbsp; Choose the appropriate viscosity and correct usage method. Adhesive with thixotropy can also prevent flow< br />
& nbsp; & nbsp; Industrial adhesives - What changes do adhesives undergo at low temperatures< br />
& nbsp; & nbsp; Most products can maintain good performance at very low temperatures to provide better protection, such as silicone products, which can maintain excellent elasticity at temperatures as low as minus 30 degrees Celsius or even lower.
