The majority (70%) of a polymer matrix cross-linking cycle occurs within 30 – 45 minutes of its initial wipe-on application drying; however it is recommended that a period of 12 - 24 hours is allowed for the cross-linking process to complete, otherwise polymerization and durability may be compromised Although it should be noted that surface oils or silicone and / or moisture introduced before the cross-linking process is complete will interfere with the bonding of a polymer and will negatively affect its durability
