Thinkbond Adhesive Bonding Agent for Rubber One-coat Thermoreactive
Primer
Application Field:
Thinkbond 911HS is a one-coat thermoreactive primer for bonding
elastomers as NBR, ACM and solid PU with steel, carbon steel, alloy
steel, stainless steel, aluminum, copper alloy, aramid, textile
fibers and glass by vulcanization process. The textile fibers can
be: - Cotton, cellulose, polyamide, polyester and aramid. Thinkbond
911HS is also used in two coats systems together with an adhesive
to bond NR, SBR, BR, CR, NBR, HNBR, IIR, CIIR, BIIR, CSM y EPDM.
Properties:
- Appearance : Grey liquid.
- Non-volatile solids (1h @ 105°C) : 22,00-26,00%
- Density at 25°C : 0,92-0,96 g/cm3
- Viscosity Brookfield at 25°C : 150 cps.
- Diluents : MEK / MIBK Bonding
- Temperature Range : 135 to 200ºC
- Shelf life : 1 year (closed can below 25ºC).
Chemical composition:
Polymers and fillers stabilized in aromatic and ketone solvents.
How to prepare the surface:
Prepare the metal surface properly by removing completely oil,
grease and dirt. Blasting the surface with grit blasting steel so
that the surface roughness is greater than 15 µm. For aluminum
surfaces, we recommend the use of aluminum oxide as abrasive. Clean
again the substrate to remove dust from blasting residues.
Thinkbond 911HS can be applied on surfaces treated by chemical
processes such as galvanizing, phosphating, KTL...
Application:
Agitation: We recommend stir Thinkbond 911HS before the application
to avoid sedimentation.
Dilution: Diluent: MEK or MIBK
Dilution ratio: Dipping: For this application, we recommend
diluting between 50 and 100% v/v. Brushing: For this application,
we recommend diluting between 20 and 50% v/v. Spray: For this
application, we recommend diluting between 50 and 100% v/v.
Drying time: approx. 15 - 30 min at room temperature. If it is
necessary to reduce drying time, we recommend using forced air for
2 minutes at 65ºC maximum. For drying, do not use process
temperatures above 82ºC in order to avoid adhesive pre-cure. After
this process, follow instructions to vulcanization.
Storage:
Keep container tightly closed during storage and always keep away
from heat sources. Store in an environment below 10ºC increases the
shelf life of the adhesive.
