UVIKOTE 7503LMAUTO-PMF

TECHNICAL DATA & INFORMATION –  Click to view complete technical

UV Curing, Low Modulus, Low Outgassing, Urethane Conformal Encapsulant/Coating


PRODUCT DESCRIPTION

UVIKOTE 7503LMAUTO-PMF is a low viscosity, ready to spray, one component, premixed frozen liquid, electrically insulating, transparent, urethane coating designed for the encapsulation and protection of electrical/electronic components mounted on printed circuit boards. This system provides an excellent combination of flexibility and low modulus for demanding applications where the management of thermomechanical stresses is required.

UVIKOTE 7503LMAUTO-PMF coating will become tack free when exposed to the proper UV light radiation. The coating will fully post cure in both the exposed and shaded areas in 14 days at 25°C and 50% relative humidity. As an alternative, the post cure for the coating in both exposed and shaded areas may be accelerated with low to moderate heat.


KEY FEATURES AND BENEFITS

• Qualified to Mil-I-46058C and IPC-C-830C
• Multicure mechanism for complete cure in shaded areas underneath components
• Excellent flexibility and low modulus, low Tg, for reduced stress in the encapsulation of sensitive components (e.g. glass-bodied diodes)
• Meets NASA condensable volatile requirements for high vacuum environments
• Highly reversion resistant for good physical stability under high heat and humidity environments
• Excellent adhesion to plastic/metal components and substrates. Adheres well to itself for multicoat and repair applications
• Ready-to-spray viscosity formulated to have specific viscosity range for automated equipment
• No TDI, toxic solvents, or free acrylic acid for safety
• Complete companion UV product line available:

• UVIKOTE 7504LM-PMF – 100% solids for thicker applications such as the back-side solder joint encapsulation
• UVISTAKE 7205LM-PMF – thixotropic, non-flow adhesive for wire tacking and component staking
• UVIKOTE 7503, 7504 Thinner – non-photosensitive, non-aromatic, thinner for lowering viscosity of UVIKOTE 7503LM-PMF, UVIKOTE 7503LMAUTO-PMF, and UVIKOTE 7504LM-PMF
• UVIKOTE S-100 Stripper – low viscosity stripper for the removal of cured coating/adhesive for repair operations
• UVIKOTE S-200 Stripper – thixotropic stripper for localized removal of cured coating/adhesive
