China Two Component Epoxy Structural Adhesive Comens Weld SL2620t

Comens Weld SL2620T is a two component epoxy structural adhesive. The product is a tough adhesive with high thixotropic properties. This product is mainly used for the opening of the composite material in the vehicle, the sealing of the metal rough surface, the filling and sealing, the smoothing repair, etc.; and the self-adhesive or mutual adhesion between the metal and the SMC substrate. This product has high bonding strength, high compressive strength, impact resistance, corrosion resistance and aging resistance.♦Low shrinkage rate ♦ Low density ♦Pot life 60-80min
♦ 100% curing♦ High thixotropy, suitable for filling gaps metal: aluminum, cold rolled steel, magnesium alloy, stainless steel
Composite material: FRP
Thermoplastic: PVC, acrylic, phenolic plastic, polycarbonate, fluoropolymer
Other materials: fabric, foam, glass, wood, rubber Note: The following information and data are typical values under standard conditions, not as a basis for product acceptance. If the test environment is not explicitly mentioned in the following tests, the test environment is unified to a temperature of 24 ± 2 ° C and a humidity of 50 ± 5% RH.PropertySL2620T PASL2620T PBMixedColorWhiteLight blueLight blueDensity /g/cm30.60±0.050.60±0.050.60±0.05StatuepastepastepasteViscosity /Pa.s---Pot life /min--60-80/24ºCCuring time/d2~3Applicable temperature-40ºC~120ºCMixing ratioPA/PB=2:1(Volume ratio )

The test standard for shear strength: GB/T 7124
The dielectric strength is tested by ASDM D149.
The compressive strength is tested by ISO 527-2.
The hardness test standard is: ISO868Can withstand:Acid and base (PH3-10), hydrocarbons, brine
Can't withstand:Polar solvent, strong acid and alkaliProduct specification: 0.5kg/ pail, 2kg/ pail.
The recommended storage temperature is 8~25°C and the storage period is 12 months.
Storage at 25°C helps to extend the shelf life of the product. Long-term exposure to room temperature and above will shorten the shelf life of the product.
Do not expose the product to high temperature storage. Recommended storage environment: ventilated, dry and dark.When bonding, the surface to be bonded is wiped clean with a cleaning agent such as acetone or alcohol or gasoline to remove surface dust, oil and other stains. If the bonding surface can be roughened by grinding or the like, the bonding strength is better.
