Many users told LLPT that the primer wipes dried out when they received it; LLPT came up with the solution to improve package seals & providing extra primer supplement. The new package improves the dried out issue significantly and extends the validation period up to 12 months (supplement is 3 years). If there is any sign of dry-out wipe, use the brush in the bottle to apply the primer on the surface and then use the sponge wiping all over the surface evenly for best bonding result.
Commonly used on low surface energy materials to increase the initial bonding strength and curing better for long term performance of adhesive.
Extremely helpful for Acrylic Double Sided Adhesive for a secured bonding initial bonding.
2cc per packet, use it within an hour after the packet is opened. Cover up and tighten the cap of supplement bottle right away after use.
Not only works on LLPT double sided acrylic mounting tapes, but also any other brands and compatible with 3M 4298 Adhesion Promoter.
