Rubber to Metal Bonding Adhesive 815
(Equivalent to Chemlok 205,Chemosil 211,Cilbond 10E/12E)
1. Description
Our 815 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.
2. Typical Properties:
- Component: High polymer, organic compound, inorganic filler and
organic solvent.
- Color: Gray
- Viscosity: (25℃, Brookfield LV2 30rpm) 70-150cps
- Solid Content: 23-26%
- Flash Point: 22-24℃
- Diluents: METHYL ETHYL KETONE(MEK), Methyl Isobutyl Ketone (MIBK)
- Solvent: METHYL ETHYL KETONE(MEK), Methyl Isobutyl Ketone (MIBK)
- Shelf life: 12months in unopened containers(25℃)
3. 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.
4. 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 815 with 20 portion diluents like
MEK or MIBK
- Spraying: 100 portion of 815 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 815, 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.
5. Cautionary Information
Close the diluents container tightly after use.
The diluents vapor is hazardous. Prevent long time inhalation or
skin contact in working place.
