HumiSeal 1A34 conformal coating

HumiSeal 1A34 conformal coating is a single component, fast curing polyurethane conformal coating. 1A34 offers easy application and handling.  It fluoresces under UV light for ease of inspection. Qualified to MIL-I-46058C and compliant to IPC-CC-830 and RoHS Directive 2002/95/EC.

Apply HumiSeal 1A34 to clean substrates or assembled with low residue “no clean” materials.  Perform adequate testing to confirm compatibility between the conformal coating and materials, process conditions and cleanliness level.  Please see TDS for more information.

Depending on the assembly, it may be necessary to use HumiSeal® Thinner 521 or 521EU to obtain a uniform film. Refer the TDS for more information.
HumiSeal® 1A34 can be sprayed using conventional spraying equipment. HumiSeal® Thinner 521 or 521EU  may be necessary to ensure a uniform spray pattern resulting in a pinhole-free film. Refer the TDS for more information.
HumiSeal® 1A34 may be brushed with a small addition of HumiSeal® Thinner 521 or 521EU. Uniformity of the film depends on component density and the operator’s technique. Refer the TDS for more information.

Safety Precautions: Comply with all local safety, disposal and transportation regulations. Check the Safety Data Sheet (SDS) and label of the individual products carefully before using the products. SDS’s are available on request.
