(A) room temperature curing method: a total of four ingredients formulated, the bonding process must be particularly careful and serious. 1) 100 g of epoxy resin is heated at 70 ° C. 2) Dibutyl ester 15-20 g. 3) 15 grams of aluminum oxide. > Add epoxy resin together to reduce the temperature to 55 ~ 60 ° C. 4) Ethylenediamine 6-8 g Slowly add the first three mixtures and stir to cool to 35 ° C. After the smokeless, stir for 3 minutes. This method should not be too much in one dose because it will cure within 24 hours of the formulation. The magnetic block must be ketone when bonding Wash and sweep the magnetic block with rubber wood. If the formulated adhesive is bubbling, it cannot be used. (2) Polyurethane adhesive group A: (also called A and B) Formulation ratio: 3 in group A and 1 in group B. Mix well and use.

What are the commonly used magnetic block bonding materials and methods?
There are two main methods of bonding magnetic blocks: one is the room temperature curing method, and the other is the polyurethane adhesive group A (crosslinking agent). The first method is slow, and the latter can be bonded directly faster.
