British Siben CIL adhesive-CILBOND 45SFC
January 26th, 2010 by psoriasis8 CILBOND45SFC is a kind of one-component solvent-based adhesives, suitable for casting and the TPU and metal bonding.
Overview
CILBOND45SFC for injection TPU and metal bonding, as well as casting and metal casting polyurethane adhesive. Cast polyurethane curing temperature :30-135C; TPU injection bonding temperature to 200C. In addition to metals, but also can be epoxy adhesive substrate, solder glass-reinforced plastics, nylon and other engineering plastics, such as thermoplastic polyester elastomer body (Hytrel),, polyphenylene sulfide (PPS), polyether ether ketone (PEEK), polyether sulfone (PES), nylon (Nylon), polyethylene terephthalate (PET), poly-p-phenylene 2 Butanediol acid esters (PBT), and so has a good adhesion properties. CILBOND45SFC has excellent long pre-curing properties; outstanding resistance to hot and cold water performance.

CILBOND45SFC application
CILBOND45SFC for casting and injection molding Polyurethane and metal or plastic such as bonding, curing temperature of 80 ° C. Especially suitable for dynamic environment, and water solution required applications. Dry film thickness of 25 microns, CILBOND 45SFC has excellent resistance to salt spray performance, 40C, 5% of NaCl in 400 hours, does not appear edge corrosion or unglued. For the casting polyurethane, curing temperature is below 80 ° C, we can use pre-cured 90 ° C-100 ° C, pre-cured for 1 hour. Low-temperature curing, it can be used CILBOND45SFC + CILcure B (100:5 to 100:10 mass ratio of the mixing ratio), this mixture is valid time for 8 hours, glue pieces of parking time can be to 24 hours. CILCURE B can improve the adhesive strength when the low-temperature curing, and display excellent solvent resistance and water resistance. When the mixing ratio of 100:10 maximum when the coating in the UV light, will turn yellow. When the low-temperature curing, but also the quality of mixing can be used 100:5 ratio CILBOND45SFC: IPDI (isophorone diisocyanate), the validity of the system is greater than 12 hours after coating park for more than 36 hours. IPDI can improve resistance to yellowing under UV light stability, and, of aroyoga matic and aliphatic polyurethane has good adhesive properties, even in low-temperature curing conditions for a long time. Adhesive products have to be parked at least 7 days before in the harsh environment. Adhesive pieces have a good resistance to hot and cold water and various other liquids.
roller for paper, textile and rubber roller, solid tires, castors, and pipe-lining and so on.
metal surface treatment
for bonding, metal surface treatment is particularly important, the need to avoid all kinds of pollutants, residues, these pollutants will cause a great impact bonding, leading to degumming. Sandblasting is the most common surface treatment method of choice of 200-300 micron particle size of quartz sand or aluminum oxide. Iron type of metal, blasting to get the desired effect off-white and then solvent degreasing treatment. Other surface treatment methods have phosphating and chrome treatment, acid-base processing, and chemical reagents. Chemical treatment it is important to stay in the solution time, solution concentration,yoga mat bag, temperature control. As well as the timely replacement of cleaning fluid to prevent cleaning incomplete.
CILBOND45SFC pieces of zinc or galvanized steel, melt bonded epoxy (FBE) and other substrates with good adhesion properties.
CILBOND45SFC use
Brushing: Brushing the direct dilution from time, but for a large area Brushing products, using the following mixture of diluent can increase the flow rate of sexual and brushing.
dipping? 25 ° C, using the following mixture of diluent, diluted to the viscosity of 16-24 seconds (No. 2 Zahn cup), or 13-20 seconds (No. 4 Din cup or 4 Ford cup); if asked volatile fast.
spray? 25 ° C, using the following mixture of diluent, diluted to 16-24 seconds (No. 2 Zahn cup), or 13-20 seconds (No. 4 Din cup or 4 Ford cup); nozzle diameter: 1.0-1.5mm, air pressure: 1.5 bar. too much pressure will lead to snag the phenomenon. If a snag phenomenon, add more thinner or the use of high boiling point solvents, such as the MPA (propylene glycol methyl ether acetate). If you only use methyl ethyl ketone as a diluent, as butanone volatile very quickly, resulting in the rapid cooling of metal surfaces, allowing moisture accumulation, leading to dry the surface of bubble.
roller coating-CILBOND 45SFC diluted to 35-45 seconds (No. 4 Din cup or 4 Ford cup); using high boiling point solvent MPA (propylene glycol methyl ether acetate), get the best coating and to avoid coating from folds.
dry? 25 ° C, each time dry, at room temperature for at least 45 minutes guaranteed, and the last time, after brushing to ensure that more than 1 hour drying time. Less than 20 ° C, corresponding to extend the drying time. Forced dry, the need to avoid air bubbles produced film. Therefore, requiring dry, avoid air bubbles, to be gradually heated to 60 ° C.
pre-cured? CILBOND 45SFC through the pre-curing, can improve the adhesion with the substrate. At 100 ° C, the pre-cured 1 hour, may be extended to 2 hours for up to 4-8 hours to get the best adhesive strength, with a plastic, heat-resistant properties. Although the higher temperature and longer period of time will not affect the adhesion results, but, 100 ° C, 48 Xiaoshi; 110 ° C, 24 Xiao Shi; 120 ° C., 15 hours; Chaoguo 130 ° C, to be carefully controlled .
dry film thickness? normally available 15 micron dry film thickness of a good bonding results. For dynamic fatigue resistance and harsh environmental requirements, it is recommended more than 25 microns can get a very good resistance to salt spray performance, 400 hours of salt spray test, does not appear pouch belt phenomenon of edge unglued.
diluted - the best mixed diluent diluent, see the following (mass ratio):
86 copies of methyl ethyl ketone (MEK) +7 copies of propylene glycol ether acetate (MPA) +7 copies of ethoxy Ethyl (Ektapro EEP)
this mixed diluent is CILBOND DILUENT 4000. For most applications, can be used to dilute pouch water content of low-butanone. If you snag when spraying phenomenon, can be used methyl ethyl ketone and high boiling point solvents, such as the MPA, mixed thinner.
packaging standards
CILBOND 45SFC are 10L, 25L and 200L three kinds of packaging.
