What is a plastic resin adhesive?
plastic resignation adhesive, commonly known as the adhesive for urea resins, is mainly used in the working industry as a structural adhesive. This adhesive is available in both liquid and powder form. Liquid resin generally comes with a powder catalyst, while the powdered plastic resin adhesive is usually catalyzed and pre -created and can be easily mixed with water. The date of the pre -series means that urea and formaldehyde, adhesive components, are already mixed; In general, this adhesive does not require hard stirring. The powder should be added slowly to the water and gently mixed until the consistency of a similar cream reaches. The powder that settles on the sides of the container should also be scraped into the mixture until the final result is smooth and without pieces. This police life drops to less than six months if it is stored at a high temperature, approximately 90 ° F (32 ° C) and high humidity. If powdered plastic resin adhesive with a mixture of water to provide granular conEvidence, not suitable for use. In addition, if the powder does not easily dissolve in the water, it is quite a clear sign that the product has undergone its life.
The time that takes the adhesive will solidify or the "treatment time" ranges from eight to ten hours depending on the ambient temperature. Therefore, this adhesive is suitable for use in wood applications, where it is common to build parts. The higher the outside temperature, the faster the cure process is.
plastic resin adhesive can be hot or cold pressed. It can also be radio frequencies. One of the main advantages of plastic resinous adhesive is its longer "open time" than many other adhesives, which is more than half an hour. The open time refers to the duration between when the adhesive is applied when the material is placed in the print.
"Potle Life", the time between mixing and use ranges from four to five hoursIn if the ambient temperature is around 70 ° F (21 ° C). The adhesive may be cooled to extend the life of the pot, but not below 55 ° F (12.7 ° C), as it can adversely affect the ease of application. Freezing of the adhesive is not suitable.
plastic resin adhesives are widely used for laminating and veneer applications. When working with raw veneers, it is necessary to use a thin spread of adhesive so that it does not penetrate. Plastic resin adhesive is the ideal choice as a structural adhesive resistant to water and heat and wooden adhesive.
