Introduction to Plastic Adhesive Models and Performance, and How to Remove 502 Adhesive from Hands
DM5925 is a quick drying adhesive, especially suitable for rapid bonding of plastics and rubber. This adhesive can also be used for difficult to bond plastics when combined with DM primer of cyanoacrylate adhesive. Adhesive plastic and EPDM rubber can instantly bond O-rings with extremely low viscosity, forming a dense adhesive layer. It is an ideal choice for all quick repairs related to plastic and rubber substrates.
DM5151 primer can improve the adhesion of difficult to bond substrates. Fixed time of 15 seconds, filling gap length of 0.1 millimeters, shear strength of 3200 pounds per square inch (22 Newtons per square millimeter), temperature resistance (continuous use) of 120 ° C, viscosity (centipoise) of 20.
DM5925 is a colorless and transparent low viscosity universal instant dry adhesive that can achieve rapid bonding. It can bond various materials including plastic, rubber, and metal. When used in conjunction with primer, it can also bond polyolefin. DM5011 is a quick drying adhesive suitable for various difficult to bond materials that require uniform stress distribution and high tensile and/or shear strength. This product can quickly bond various materials, including metals, plastics, and elastomers.
Plastic glue is made up of high molecular weight polymers in water (vinyl acetate in white glue is a type of petroleum derivative), which are circular particles with a radius generally between 0.5 and 5 μ m. The bonding of objects is achieved by the tensile force between the polymer molecules in plastic glue. In plastic glue, water serves as the carrier for the medium to high molecular weight polymer, slowly immersing it into the tissue of the object.
After the moisture in the plastic glue disappears, the high molecular weight in the plastic glue relies on the mutual tension to tightly bond the two objects together. In the use of plastic glue, excessive application of glue can cause the polymer molecules in the glue to crowd together; Polymer molecules cannot generate good tensile forces.
Polymer bodies are crowded with each other, resulting in a lack of strong attraction between them. At the same time, the water between polymer molecules is not easily evaporated. That’s why in the bonding process, the thicker the adhesive film, the worse the bonding effect of the glue. Too much glue is applied, and the large amount of glue plays a “filling role” rather than a bonding role. The bonding between objects does not rely on the adhesive force of the glue, but on the “viscosity” of the glue.
Precautions for using plastic glue:
The surface of the plastic adhesive should be clean and dry. Oil stains and other substances can be cleaned with solvents such as gasoline and acetone. Apply the adhesive solution evenly to the surfaces of the two adhesives, wait for 3-6 minutes, and align the two adhesives for bonding. Apply a little pressure to make the bonding surface denser, and let it sit for several hours. After 48 hours, it will be completely cured; For materials with high bonding requirements such as metals and hard plastics, tools such as iron sandpaper can be used to roughen them. Two coats of glue (wait for a few minutes after one coat, then apply the second coat of glue, and dry it slightly to close it together) have a better effect.
When 502 glue sticks to your hand, you can try the following methods to remove it. Firstly, you can gently wash your hands with warm soapy water and warm water, and then wipe the adhesive area with lemon juice or vinegar. If these methods are ineffective, you can try using cooking oil or moisturizer to soften the glue, and then rinse with warm soapy water. In addition, specialized adhesive removers can also be used, but please be sure to follow the instructions in the product manual. Please be careful not to forcefully tear the glue to avoid damaging the skin. I hope the above methods can help you effectively remove 502 glue.
