What sealants can be used with polycarbonate?
A. All silicone sealants must be low modulus (flexible), neutral cure and polycarbonate compatible. Check on the tube or with manufacturer for compatibility before using general purpose silicones etc. All sealing tapes, breather tapes and gaskets should be made of a compatible material such as aluminium foil, EPDM or neoprene rubber. See the Sheet Maintenance Advice.pdf for general guidelines on these topics.
