HumiSeal 1B73 LED PB 25 CPS is characterized by a higher degree of optical clarity and greater resistance to damage by sunlight than standard conformal coatings. HumiSeal 1B73 LED PB 25 CPS demonstrates excellent flexibility and electrical properties. HumiSeal 1B73 LED PB 25 CPS coating is RoHS Directive 2011/65/EU compliant.
Application of HumiSeal 1B73 LED PB 25 CPS
Conformal coatings can be successfully applied to substrates that have been cleaned prior to coating and also to substrates assembled with low residue “no clean” materials. Users should perform adequate testing to confirm compatibility between the conformal coating and their particular assembly materials, process conditions and cleanliness level. Please contact HumiSeal for additional information.
HumiSeal 1B73 LED PB 25 CPS is specifically diluted to a viscosity for immediate use. No additional dilution is required. HumiSeal Technical Support should be contacted if any further advice on Pre-blends and equipment is required.
A controlled rate of immersion and withdrawal (5-15 cm/min) will further ensure even deposition of the coating and ultimately a uniform film. During the application, evaporation of solvent causes an increase in viscosity that should be adjusted by adding small amounts of HumiSeal Thinner 73. Viscosity in the dip tank should be checked regularly, using a simple measuring device such as a Zahn or Ford viscosity cup.
HumiSeal 1B73 LED PB 25 CPS can be sprayed using conventional spraying equipment. Spraying should be done in an environment with adequate ventilation so that the vapour and mist are carried away from the operator. The specific Pre-Blend and spray pressure will depend on the specific type of spray equipment used and operator technique.
HumiSeal 1B73 LED PB 25 CPS may be brushed onto surfaces. Uniformity of the film depends on specific preblend chosen and operator’s technique.
