Detailed Product Description
Clear One-Component Solvent-Based Bonding Agent for CPU/MPU/TPUProduct Description: Thinkbond 940T is a Clear One-Component Solvent-Based Bonding Agent
for CPU , MPU and TPU to hard substrates. Hard substrates include: metal substrates (steel, iron, aluminum,
etc.) and non-metal substrates (epoxy resin, glass-reinforced
plastics, polyphenylene sulfide, polyetheretherketone,
polyethersulfone, etc.). Thinkbond 940T is a heavy metals free product. BENEFITS: Thinkbond 940T is a one coat bonding system for PU’s and TPU’S to
all metals during the curing process. Thinkbond 940T will also bond polyurethane elastomers to polyamides
and other engineering thermoplastics, such as Hytrel® , polyester,
PES, PPS and PPO, at 80ºC or above. Thinkbond 940T has excellent environmental resistance to hot and
cold water, fluids. TYPICAL PHYSICAL PROPERTIES:
CHEMICAL COMPOSITION: Resins and catalysts stabilized in organic solvents. METAL SURFACE PREPARATION: 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. If specified, the metal part can be phosphatized, galvanized,
chromate conversion treated or KTL, before applying adhesive. APPLYING Thinkbond: Agitation: We recommend stir Thinkbond 940T before the application to avoid
settle down. Brushing: Application by brushing is normally undertaken without further
dilution, but for coating large areas, dilution with MEK (or the
diluent blend shown below) improves flow and speed of application. Spraying: We recommend an HVLP gun using 1.5 Bar air-pressure and a nozzle
size of 1 - 1.5mm. For this application we recommend diluting
between 50 and 100% v/v. Roller coating: Dilute to 35 - 45 seconds on a DIN 4 or Ford 4 cup at 25 C for
most roller application processes. Dilution with a high boiling
solvent like MPA may be necessary to achieve the best finish and to
reduce the skinning of the bonding agent in the applicator. Drying: Dry the film between 10 and 30 minutes at room temperature. If it
is necessary to reduce drying time, we recommend to use forced air
for 5 minutes at 100ºC maximum. Do not use in this stage
temperatures above 100ºC to avoid adhesive pre-cure. After this process, follow to cure. Thickness of application layer: The film obtained by applying Thinkbond 940T is colorless. The
layer thickness must be between 15 and 25 µm. For severe environments or dynamic fatigue applications, use ≧25
microns. Under these conditions it is possible to achieve bonds
with no edge-failure after 400 hour salt-spray tests Parts with Thinkbond 940T already applied can be stored for 30 days
prior to cure. STORAGE: Keep container tightly closed during storage and always keep away
from heat sources. Store in anenvironment below 10ºC increases the
shelf life of the adhesive. Shanghai LoreChem Co., Ltd. was established in 2008. It is a
high-tech enterprise which is dedicated to serve releasing products
which involve semi-permanent release agent, anti-sticking, surface
