TECH SHEET 20.2 LFP COMPOUND To: Vinyl and Leather Repair Professionals Subject: LFP (Low-Fusing Plastisol) USES: Leather filling, unbacked vinyl door panels, and wherever the Hot Graining technique is needed. (This is where only the gun-heated texture mat is applied for curing.) Advantages of LFP: Lower risk of damage to heat sensitive substrates Much lower viscosity (to promote soak-in to adhesive primed leather edges) Greater flexibility and better low temperature flex Can be cured using Hot Graining technique Disadvantages of LFP: Only small amounts can be taken on the job during hot weather In cool, sunny weather, it may harden if kept in car or trunk. Instructions: To speed up the curing time and lower the temperature needed to cure LFP, add Flex Magic to LFP before application. The mixing ratio is _ LFP and _ Magic. Magic will thicken the uncured LFP. You will have little working time with the mixture before it becomes too stiff to spread. For through-cuts in leather use vinyl underlay adhered with the A Adhesive. Moisten leather edges with the A Adhesive or the new Cor Flex (for priming and better adhesion of LFP). LFP will leave a featheredge on the surface of leather. To entirely eliminate this featheredge, mist on a couple of coats of Prima Flex and hot grain when dry to touch. For vinyls noted above, use the Fine Mesh. Stick the mesh on using the Mesh Adhesive or a thin coat of LFP -- just wet. Apply subsequent thin coats, hot graining each one. Eliminate any band (loss-of-emboss) by misting two coats of Barriercoat, dry to the touch and finish with the hot grain. Remember LFP is not fully cured until crystal-clear and the surface takes on that wet look. It must be clear as glass. When Magic has been mixed in, a cloudy finish may result in the compound even though LFP is fully heat cured.
