Thin Film Coatings
For high performance
BECTRON® Thin Film Coatings are suitable for many process methods including select coat,
spray, dip and selective flooding. Examples of applications include PCBs for the automotive and
marine navigation industries, PCBs for industrial electronics, hybrid circuits, SMD assemblies
and other discrete electronic components.
Air Drying Resistant Coating
BECTRON® PL4122 BLF is a lead-free coating range based on urethane-alkyd varnish for
conformal coating of printed circuit boards (PCBs) and hybrid circuits. BECTRON® PL4122 BLF
products are free of aromatic solvents and meet the latest performance characteristics for
electronics, including low pin corrosion and fast curing at oven and room temperature.
Conveyor oven systems permit very short cure times, below 10 minutes.
Rapid Process Acrylic Coatings
BECTRON® PL1102 and PL1104 are air dried coating, short cure times of 15 minutes at +25 °C
to give a general protection for PCBs and related applications and are free of aromatic solvents
and meet the latest performance characteristics for electronics.
UV / oven Drying Coating
Bectron® PL 5622-250 is a VOC-free conformal coating with the excellent electrical performance
and adhesion to most surfaces. It can be cured by UV irradiation and/or heat. Bectron®
PL 5622-250 has very good temperature cycling behavior from -40 °C to +150 °C for requirements
BECTRON® PT 4600
Is a VOC-free, 1k polyurethane based and cured by UV irradiation and/or moisture. For easy
process control, the color changes from blue to green/yellow to indicate the degree of UV- curing.
BECTRON® PT 4600 is qualified according to UL 94 V-O (File-No. E211569).
UV cure is rapid, within seconds and moisture cure follows naturally for 2–3 days. The cured
product has very good temperature cycling behavior from -40 °C to +120 °C and good adhesion
on most substrates.
BECTRON® SC 75V1-16 is a VOC free silicone coating with high thermal performance, very fast
curing at +90 °C possible also curing at room temperature. BECTRON® SC 76 conformal coatings
are fast humidity curing silicones with excellent electrical and temperature shock properties.
Thin Film Coatings
BECTRON® Thin Film Coatings provide optimal protection to electronic assemblies against
moisture, chemicals, mechanical stress, dust, contaminants, corrosive gases and other impurities.
Cured film properties include:
High temperature index (up to +200 °C @ 20.000 h)
Excellent thin film dielectrics
Protection against several environmental influences
Very good chemical resistance
Excellent PCB adhesion withstanding several temperature cycles of -40 °C to +180 °C
