Humiseal 1B51 NSLU Synthetic Rubber Conformal Coating
Product Information
HumiSeal 1B51 NSLU conformal coating is:
- a fast drying
- single component
- synthetic rubber
- environmentally friendly solvent blend
HumiSeal 1B51 NSLU conformal coating has:
- excellent moisture and environmental protection for printed circuit assemblies
- extremely low moisture vapor permeability
- excellent flexibility, enabling low stress on components
- full compliance with the RoHS directive 2015/863/EU
- UV additive for fluorescence
Application of HumiSeal 1B51 NSLU
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.Dipping
Depending on the complexity, density and configuration of components on the assembly, it may be necessary to reduce the viscosity of HumiSeal® 1B51 NSLU with HumiSeal® Thinner 903, 905, 521EU in order to obtain a uniform film. Once optimum viscosity is determined, a controlled rate of immersion and withdrawal (5-15 cm/min) will further ensure even deposition of the coating and 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 903, 905, 521EU. Viscosity in the dip tank should be checked regularly, using a simple measuring device such as a Zahn or Ford viscosity cup.Spraying
HumiSeal 1B51 NSLU can be sprayed using conventional spraying equipment. Spraying should be done in an environment with adequate ventilation so that the vapor and mist are carried away from the operator. The addition of HumiSeal Thinner 521 or 521EU is necessary to ensure a uniform spray pattern resulting in a pinhole-free film. The amount of thinner and spray pressure will depend on the specific type of spray equipment used and operator technique. The recommended ratio of HumiSeal 1B51 NSLU to HumiSeal Thinner 903, 905, 521EU is 1:1 by volume; however, the quantities may need to be adjusted to obtain a uniform coating.Brushing
HumiSeal 1B51 NSLU may be brushed with a small addition of HumiSeal Thinner 903, 905, 521EU. Uniformity of the film depends on the component density and the operator’s technique.Delivery Information
