摘要:
The present invention relates to water soluble fluxes which comprise at least one wax carrier, at least one surfactant and at least one activator. The present water soluble fluxes are easily applicable with a brush. They have excellent pull through of solder in the joint. The water soluble flux avoids tuning copper green and does not burst into flame on heating with a torch.
摘要:
A composition is described with comprises a mixture of
(A) from about 5% to about 60% by weight of at least one water-insoluble polymer; (B) from about 1% to about 30% by weight of inorganic or synthetic resinous hollow microspheres; and (C) from about 20% to about 70% of at least one volatile organic liquid which is a solvent for the polymer of (A). The compositions also may contain (D) at least one solid particulate inorganic filler. Adhesive compositions such as solvent cements prepared in accordance with the present invention are characterized as low VOC compositions wherein the VOC is, for example, less than 500 or even less than 400 grams per liter.
