Precise Peelable Mask

TECHNOMELT AS 8998 is a new and efficient approach to conventional PCB masking techniques for conformal coating processes.

An alternative to manual taping methods, TECHNOMELT AS 8998 is a hot melt adhesive that can be precisely applied to keep-out areas via automated dispensing systems, reducing process time and labor costs.

The material is compatible with conformal coating chemistries, delivers better control during conformal coating, requires no curing and releases cleanly from various substrate surfaces.
