Thick Film Coating – Moisture / UV cure
For high performance
Optimal Protection for extreme Demands
BECTRON® PT 46.. UV & moisture cure is a solvent-free, zero VOC, one-component
polyurethane based thick film coating, cured by UV irradiation and/or by moisture. It provides
an ideal VOC-free conformal coating with very short process time. For easy process control,
the colour 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 and can be
accelerated by heat and humidity.
The cured product shows very good temperature cycling behaviour from -40 °C to +120 °C
and good adhesion on most substrates. It is strong enough to form a support to secure large
components, acting as an adhesive.
The viscosity is low, suitable for rapid automated robotic coating with a choice of application
systems such as spraying, dispensing or jetting with reliable edge-covering of sensitive
components.
BECTRON® PT 48.. series one-component moisture-cured polyurethane based thick film
coatings are used for protecting and mechanically supporting connections and components
of PCBs and hybrids. The whole range has low VOC contribution. The cured product is elastic
over the range -50 °C to 120 °C with good adhesion to most substrates to resist vibration.
BECTRON® PT 48.. series is resistant to solvents and dilute acids and alkalis providing excellent
protection against moisture migration and corrosion after severe wet storage conditions.
PT 48.. series offers the reliable dielectric properties expected from all BECTRON® products.
3 different viscosity levels, from 1,400 mPas to a viscous thixotropic grade, permit a wide
range of applications and processes. BECTRON® PT 48.. cures at room temperature to a
dry surface condition in 1–2 hours and further processing is possible a few hours later.
BECTRON® SC 76V1-36 is a solvent free, one component silicone coating curing with moisture
at room temperature. The cured product shows very good temperature cycling behavior from
-55 °C to 200 °C.
