Q1: What makes Deflamer LF-8005 suitable for halogen-free PCB inks?
A: Deflamer LF-8005 is a phosphorus-based flame retardant specifically engineered to deliver effective fire resistance without halogenated compounds, supporting compliance with RoHS, REACH, and industry requirements for low-smoke, low-toxicity PCB materials.
Q2: How does LF-8005 affect ink viscosity and printability?
A: LF-8005 exhibits good compatibility with common PCB ink resins and solvents, and when properly dispersed, it typically causes minimal impact on viscosity or rheology—enabling stable screen printing and consistent film formation.
Q3: Is LF-8005 compatible with UV-curable and thermally cured ink systems?
A: Yes—LF-8005 has demonstrated compatibility with both UV-curable acrylate systems and conventional thermally cured epoxy- or phenolic-based PCB inks, maintaining flame retardancy performance after full cure.
Q4: What is the typical dosage range for optimal flame retardancy in PCB ink formulations?
A: Dosage depends on resin chemistry, filler content, and target flammability rating (e.g., UL 94 V-0), but LF-8005 is generally used at low concentrations—typically ranging from 0.1% to 2% by weight of total ink solids—to balance performance, adhesion, and electrical insulation properties.
