Can silicone stick to metal?

22 Oct 2019

With the use of silicone materials in daily necessities more and more widely.

But sometimes our silicone products factory will encounter some difficult problems, such as silicone and metal bonding problems, always encountered adhesion, bubble, degumming.

Today from this design, process, silicone and metal binder selection analysis why you do not stick.

First of all, the metal surface treatment to bond.

According to the actual selection of 3 methods: chemical, mechanical, solvent.

The purpose is to roughen the surface of the metal and clean it of oil and dust.

Second, when designing products.

The bonding area between metal and silicone surface should be increased as much as possible.

Force mode prevents stripping force, using shear force or tensile force.

Choice of metal materials to avoid the choice of scarce metal, stainless steel, aluminum alloy, iron, metal, galvanized nickel plating can be bonded with silicone, and the cost is lower.

Thirdly, the choice of silicone and metal bonding agent is more important.

Silicone and metal bonding is divided into: room temperature fast dry, room temperature slow dry, silicone hot vulcanization mold bonding, liquid silicone and metal bonding.

Each bonding method corresponding to the bonding process is different, the same as the corresponding special silicone adhesive, can not be confused.

Metal material and bonding process determine the type of glue.

Common silicone and stainless steel adhesives, silicone and aluminum adhesives, silicone and iron adhesives.

Taken together, silicone and metal can be bonded.

The key is to metal surface treatment and the choice of special silicone and metal adhesive.

In addition, special attention should be paid to the certification of food grade environmental protection.
