CBA is a polyester-based core bedding compound, developed for both hand lay-up and vacuum-bagcore installation, and is used as a 2-part system in NOTE: Always prime the core surface with a conjunction with a priming resin applied to the catalysed resin. The CBA combines with the priming core surface. Lightweight and non-sagging, CBA is resin for a thorough cure and good cohesion. The formulated to the degree of elasticity required for the priming resin should appear between the blocks of core to skin interface. With a shrinkage of less than contoured foam or balsa, or in the bleeder holes of 1%, CBA significantly reduces the possibility of print- plain core, for a visual inspection of a good bond.
through. CBA is easily applied with a trowel, to Priming resins used are normally low styrene content achieve a thin bond-line of 0.8mm which will provide (below 40%), medium reactivity GP/ortho resins, ortho/DCPD blends, vinylester resins, orvinylester/DCPD blends.
Iso resins may not work as well, especially in higher temperatures, as they can force styrene into foams The priming resin needs to be catalysed for a 15minute geltime in a 100 gram cup. Please follow the MEKP catalyst levels recommended by thepriming resin manufacturer. This is a 2-part system consisting of CBA, which iscatalysed with a BPO (50% benzoyl peroxide) catalyst.
The objective is for the priming resin to catalyse in athin film on the core material surface at about the Catalysation with 2% BPO at 250C will provide a pot 4 litres of CBA covers approximately 2.8m² 208 grms BPO to 20 litre pail CBA by volume 6 months when stored at less than 20oC.
NOTE Stir CBA well with large-blade mechanicalmixer before and after adding BPO catalyst. Alsostir BPO catalyst before use. PACK SIZES
COMBUSTIBLE: KEEP AWAY FROM EXTREMEHEAT, OPEN FLAME, PILOT LIGHTS OR OTHERSOURCES OF IGNITION. CBA and BPO catalyst should be stored in a cool, dryarea, maintaining the temperature between 5 and20°C. Avoid storing in heat or direct sunlight.
If stored in a cold area, let CBA reach shoptemperature before use.
CBA should be kept out of the eyes and off the skin.
• Use with good ventilation and adequate safetyequipment including impervious gloves and safetyglasses.
• If skin contact occurs, remove contaminatedclothing immediately, and wash the affected areathoroughly with ATL’s 845 hand cleaner and water,avoiding the use of solvents.
• If eye contact occurs, immediately flush withrunning water for at least 15 minutes and seekmedical advice.
• If swallowed DO NOT induce vomiting, and contacta doctor of the Poisons Information Centre.
