| Pre-accelerated bonding paste based on unsaturated polyester resin. Cures at room temperature (15 - 25°C). Cured using MEKP peroxide. Appearance: TC : Contains catalyst indicator Use Areas: Product suitable for many types of thick joint bonding of composite parts. The product meets requirements for the operations of gap filling, surface filling and sealing. The product can be used as a laminating aid. Application: Surface to be bonded should be free from dust and contaminants which can adversely affect the bond adhesion strength. Preparation of surface is recommended using light abrasion / sanding followed by cleaning with appropriate solvent. The bonding paste is ready to use and reaction is initiated using the correct dosage of correct peroxide. Typical dosage is 1% to 2% w/w under normal workshop application conditions (15-25°C). Mix thoroughly to ensure homogeneous catalyst dispersion (this is assisted by use of catalyst indicators which change color in TC version). Apply a uniform bead of bonding paste onto one of the surfaces and press parts together evenly to obtain the desired thickness of bond. Typically the thickness of the joint is greater than 5mm. Allow sufficient time for cohesive bond to form between laminates before handling bonded parts. Properties / Advantages: Semi flexible bonding paste for dynamic bonding applications. Bonding paste with fibers for thick joints. Very smooth consistency, and easy to apply with a spatula or comb applicator. Due to its non shrinkage characteristics, dimensional stability of part is maintained during the curing cycle of the paste. Not suitable for use in thick bond applications. Storage / Shelf Life: Shelf-life : 4 Months. When the product is sealed in its original packing, stored indoors away from direct sunlight and direct heat sources and ideally at ambient temperature between 15°C and 25°C .
