Rubber to Metal Bonding Adhesive BA-213
(Equivalent to Chemlok 205,Chemosil 211,Cilbond 10E/12E)
Description
Our BA-213 is a heat vulcanization bonding agent for rubber and various metals. It works as general purpose primer which is equivalent to Chemlok 205, Chemosil 211, Cilbond 10E/12E etc.
Features And Benefits
- It is one coat bonding agentfor nitrile rubber (NR).
- It is also used as primer bonding agent for various metals, plastics and rubbers.
- It gives excellent adhesion to various metals like steel, stainless steel, aluminum, iron, brass, aluminum alloy etc.
- It is applicable for galvanized products.
- It is non-toxic, easily operated.
- It can be applied with different ways like dip coating, spraying, brushing, and roller coating.
- It has excellent resistance to heating, water, solvent, oil, salt, corrosion etc.
- It has high bonding strength, stability and long durability.
Applying And Handling
- Surface Preparation: All bonding surface must be contaminant (such as oil, rust, oxide etc) free to reach optimum bondingSurfaces should be grit-blasted, and then ideally degreased. Apply BA-213 after surface pretreatment to avoid surface oxidizing material generates.
- Mixing: Homogeneous mix must be ensured before applying bonding agent.
- Dilution: Proper quantity dilutes can also be added according to dosage. The diluted bonding agent cannot be stored for long time.
- Brushing: Unnecessary for dilution
- Roller coating: Unnecessary for dilution
- Dipping coating: 100 portion of BA-213 with 20 portion diluents like MEK or MIBK
- Spraying: 100 portion of BA-213 with 10-30 portion diluents like MEK or MIBK
- Coating thickness: The coating should be uniform. Drying coating thickness is 7-15 microns.
- Drying: After applying BA-213, it should be left for 30-60minutes to dry at room temperature. Pre-warming or heating will speed up drying.
- Storage: It should be stored in dry environment at room temperature. Avoid long time exposure in high humidity and temperature environment.
- After treatment: Before heating vulcanization, use cloth strip soaked with xylene or MIBK to clean the excessivebonding agent. Once cured, dilutes cannot clean the bonding agent.
- Vulcanization: For optimum adhesion effects, rubber and bonding agentshould be vulcanized at the same time. When the coated parts are placed in the mould, fill rubber inside and then close the mould to start vulcanization immediately. Recommended vulcanization temperature is 135-185℃. Recommended vulcanization time is 5-60minutes. Vulcanization pressure is according to practical situation.
