What is Metal Bonder Structural Adhesive?<\/h1>\n
In addition to traditional fastening methods such as bolts, rivets and welding, bonding is also an accepted joining technique. Metal adhesive is a natural or synthetic substance used to join or bond two or more metal surfaces with a bond that is strong and flexible enough to resist separation without the need for conventional methods such as nails and screws.<\/span><\/p>\n
What Should Be Considered When Choosing Metal Bonder Structural Adhesive?<\/h2>\n
In order to achieve the best results, it is necessary to use the metal adhesive that is most compatible with the material to be fixed.\u00a0So there are some additional factors to consider before deciding on the use of adhesive.\u00a0For example, the adhesive must be suitable for the materials to be bonded, match the manufacturing method, withstand the calculated working loads and the working environment.\u00a0In addition, surface preparation, application method, curing system and their time and costs should also be considered.<\/span><\/p>\n
Materials Using Metal Adhesives Together<\/h2>\n
The materials with which metal adhesives are used are given in the table below.<\/span><\/p>\n
What is Acrylic Structural Adhesive?<\/span><\/span><\/h3>\n
Acrylic is a type of acid that has a pungent odor (with exceptions as in Adhetron 1E1), is colorless, and is formed by the oxidation of \u201cacrolic\u201d. Polymers formed by prolonged exposure of this type of acid to heat, light or metals are also called \u2018acrylic\u2019. The molecular formula of acrylic is CH2=CHCOOH.\u00a0<\/span><\/p>\n
Acrylic adhesives are ready-to-use acrylic dispersion-based type adhesives.\u00a0They bond metal, glass, wood, ceramics, ferrite and some plastics to form a high-strength permanent bond with high impact, tensile and tensile strength.\u00a0They have wide temperature resistance (-50, +220 \u00b0C).\u00a0If acrylic adhesives are used at temperatures well above the mentioned temperatures, deterioration may occur and they may also be flammable.<\/span><\/p>\n
Acrylic structural adhesives cure with activator at room temperature. Depending on the type of adhesive, the adhesive and activator can be applied separately to the surfaces to be bonded or mixed in a static mixer just before application. Adhesive and activator should always be applied separately. When the two parts come into contact with each other, the adhesive begins to cure. There are also acrylic adhesives where the adhesive and activator have the same consistency. These are two-component systems and the adhesive and activator are applied side by side or in overlapping strips. While joining the parts to be bonded, the adhesive is also mixed. A static mixer can also be used if the mixed adhesive can stand for 5 minutes or longer. The advantage of using glue pre-mixed by a static mixer,<\/span><\/p>\n

Two-component adhesives that are liquid and used with activators have external mixing and\/or very precise mixing ratios.<\/td>\n
Adhetron metal adhesives do not require mixing.\u00a0Mixer tips can be used in very sensitive situations, but these tips do not cause small losses that will affect the material consumption.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Preliminary preparation is required on the surfaces to be connected.\u00a0In addition, it is necessary to mix the hardener and adhesive materials used very well.\u00a0Temperature and impact strengths are weak.<\/td>\n
Adhetron metal adhesives are strong adhesives and do not require prior surface preparation.\u00a0Mixing ratios are not very important.\u00a0They have very good temperature and impact strength<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
