Fluxes

Soldering Chemistry

P. Kay offers a full line of soldering fluxes developed to ensure consistent, efficient and environmentally friendly soldering. Designed primarily for the electronic assembly market. P. Kay fluxes have found their way into many electrical and industrial applications. Our flux chemistry runs the gamut from Water Soluble to No-Clean and VOC-Free formulations.

Our rosin/resin-free No-Clean fluxes have set the standard for solderability and post soldering cleanliness. Water soluble fluxes are also available for customers utilizing aqueous cleaning systems and who demand aesthetic cleanliness with minimal ionic contamination.

P. Kay Metal manufactures a complete line of no-wash rosin based fluxes developed specifically for high volume consumer electronics. All fluxes are formulated to be used in foam, wave, spray, and dip applications. Custom formulations are available upon request.

No Clean & VOC Free Fluxes

To satisfy the need for a cosmetically appealing surface, and bright shiny solder connections without cleaning, P. Kay has developed a full line of No Clean Liquid Fluxes. These fluxes were developed to guarantee an easier journey down the "environmentally friendly" path. We're committed to improving the environment...one connection at a time.

Rosin Fluxes

The proven reliability of low solids rosin flux for consistent soldering with minimal residue makes it a natural choice for traditional soldering application.

Formula Type Solids % Specific Gravity Halide Content Thinner Application Removal
DW-400 Rosin < 4.00 0.804 < .10% SM-12RXA Foam, Spray, Wave Not Required
CS-12RX Rosin < 15.00 0.825 < .30% SM-12RXA Foam, Spray, Wave Not Required

Water Soluble Fluxes

Water soluble fluxes are highly activated and require the use of aqueous cleaning systems. These fluxes produce bright, reliable solder connections under challenging soldering conditions.
