gum rosin การใช้

• Gum rosin has a milder odor and lower tendency to crystallize from solutions than wood rosin, and is therefore preferred for flux applications.
• There are three types of rosin : gum rosin ( from pine tree oleoresin ), wood rosin ( obtained by extraction of tree stumps ), and tall oil rosin ( obtained from tall oil, a byproduct of kraft paper process ).
• The name doesn't appear to be particularly localised to Australia, but it might be that more genuine turpentine is manufactured in Australia and New Zealand than elsewhere ( differential cost in the availability of crude oil vs Pine resin ? ) Some people are also using the name'Gum rosin'for rosin produced from pine trees.
