Waterproof 815 Adhesive To Bond Rubber To Metal Alternative For Chemlok 205

815 Adhesive to Bond Rubber to Metal Alternative for Chemlok 205

Application

815 Adhesive to Bond Rubber to Metal Alternative for Chemlok 205 is a heat vulcanization bonding adhesive for rubber to various metals. It works as a primer and is equivalent to Chemlok 205 and Chemosil 211 etc, but with more competitive price etc.

Characteristics

• This is a single-component bonding agent designed for nitrile rubber (NBR).
• It also serves as a primer bonding agent for a variety of metals, plastics, and rubbers.
• It provides exceptional adhesion to various metals such as steel, stainless steel, aluminum, iron, brass, and aluminum alloys.
• It is suitable for galvanized products.
• It is non-toxic and easy to use.
• It can be applied using various methods including dip coating, spraying, brushing, and roller coating.
• It exhibits excellent resistance to heat, water, solvents, oil, salt, and corrosion.
• It boasts high bonding strength, stability, and long durability.
• It demonstrates exceptional adhesion ability even under low temperatures and can bond materials at 90℃ vulcanization.

Physical Properties

Applying 815 Adhesive to Bond Rubber to Metal

1. Surface Preparation: All bonding surface must be contaminant (such as oil, rust, oxide etc) free to reach optimum bonding effects. Surfaces should be grit-blasted, and then ideally degreased. Applying 815 after surface pretreatment to avoid surface oxidizing material generates.

2. Mixing: Homogeneous mix must be ensured before applying bonding agent.

3. Dilution: Proper quantity dilutes can also be added according to dosage. The diluted bonding agent cannot be stored for long time.

4. Brushing: Unnecessary for dilution

5. Roller coating: Unnecessary for dilution

6. Dipping coating: 100 portion of Rubber to Metal Bonding Adhesive 815 with 20 portion diluents like MEK or MIBK

7. Spraying: 100 portion of Rubber to Metal Bonding Adhesive 815 with 30-100 portion diluents like MEK or MIBK

8. Coating thickness: The coating should be uniform. As primer, dry film thickness is 5-10μm. As single coating, dry film thickness is 10-15 μm.

9. Drying: After applying Rubber to Metal Bonding Adhesive 815, it should be left for 30-60minutes to dry at room temperature. Pre-warming or heating will speed up drying.

10. Storage: Rubber to Metal Bonding Adhesive 815 should be stored in dry environment at room temperature. Avoid long time exposure in high humidity and temperature environment.

11. After treatment: Before heating vulcanization, use cloth strip soaked with xylene or MIBK to clean the excessive adhesive. Once cured, dilutes cannot clean the bonding agent.

12. Vulcanization: For optimum adhesion effects, rubber and adhesive should 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. Vulcanization pressure is according to practical situation.

Notes

1. Close the diluents container tightly after use.

2. The diluents vapor is hazardous. Prevent long time inhalation or skin contact in working place.
