Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Resin shopping experience:
1. Compare - without doubt the biggest advantage that the Resin offers shoppers today is the ability to compare thousands of Resin at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Resin? Wrong! If the Resin is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Resin then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Resin? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Resin and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Resin wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Resin then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Resin site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Resin, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Resin, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
Resin or
Rosin (Oxford dictionary) is a hydrocarbon secretion of many plants, particularly Pinophyta, valued for its chemical constituents and uses such as
varnishes,
adhesives, as an important source of raw materials for organic synthesis, or for
incense and
perfume. Fossilized resins are the source of
amber. The term is also used for synthetic substances of similar properties.
Chemistry
The resin produced by most plants is a
Viscosity liquid, typically composed mainly of volatile fluid terpenes, with lesser components of dissolved non-volatile solids which make resin thick and sticky. The most common terpenes in resin are the bicyclic terpenes
alpha-Pinene,
pinene,
carene and
sabinene, the monocyclic terpenes limonene and
terpinolene, and smaller amounts of the tricyclic sesquiterpenes longifolene, caryophyllene and cadinene. Some resins also contain a high proportion of
resin acids. The individual components of resin can be separated by fractional distillation
A few plants produce resins with different compositions, most notably
Jeffrey Pine and Gray Pine, the volatile components of which are largely pure heptane with little or no terpenes. The exceptional purity of the
n-heptane distilled from Jeffrey Pine resin, unmixed with other isomers of
heptane, led to its being used as the defining zero point on the octane rating scale of petrol quality. Because heptane is highly flammable, distillation of resins containing it is very dangerous. Some resin distilleries in
California exploded because they mistook Jeffrey Pine for the similar but terpene-producing
Ponderosa Pine. At the time the two pines were considered to be the same species of pine; they were only classified as separate species in
1853.
Some resins when soft are known as
oleo-resins, and when containing
benzoic acid or
cinnamic acid they are called
balsams. Other resinous products in their natural condition are a mix with natural gum or mucilaginous substances and known as
gum resins. Many compound resins have distinct and characteristic odors, from their admixture with
essential oils.
Certain resins are obtained in a fossilized condition,
amber being the most notable instance of this class;
African
copal and the kauri gum of
New Zealand are also procured in a semi-fossil condition.
Derivatives
Solidified resin from which the volatile terpene components have been removed by distillation is known as
rosin. Typical rosin is a transparent or translucent mass, with a vitreous fracture and a faintly yellow or brown colour, non-odorous or having only a slight turpentine odour and taste.
1)It is insoluble in water, mostly soluble in alcohol, essential oils, ether and hot fatty oils,2)softens and melts under the influence of heat, is not capable of sublimation, and burns with a bright but smoky flame.
This comprises a complex mixture of different substances including organic acids named the resin acids. These are closely related to the terpenes, and derive from them through partial oxidation. Resin acids can be dissolved in
alkalis to form
resin soaps, from which the purified resin acids are regenerated by treatment with acids. Examples of resin acids are abietic acid (sylvic acid), C20H30O2, plicatic acid contained in cedar, and
pimaric acid, C20H35O2, a constituent of
gallipot resin. Abietic acid can also be extracted from rosin by means of hot alcohol; it crystallizes in leaflets, and on oxidation yields trimellitic acid,
isophthalic acid and
terebic acid. Pimaric acid closely resembles abietic acid into which it passes when distilled in a vacuum; it has been supposed to consist of three isomers.
Synthetic resins
Synthetic resins are materials with similar properties to natural resins—viscosity liquids capable of hardening. They are typically manufactured by esterification or soaping of
organic compounds.The classic variety is
epoxy, manufactured through
polymerization-polyaddition or polycondensation reactions, used as a thermoset polymer for adhesives and
composite materials. One more category, which constitutes 75% of resins used, is unsaturated polyester resin. Ion exchange resin is another important class with application in
water purification and catalysis of organic reactions. See also AT-10 Resin, melamine resin.
Uses
resinThe hard transparent resins, such as the copals, dammars,
mastic and
sandarac, are principally used for
varnishes and cement, while the softer odoriferous oleo-resins (
frankincense, elemi,
turpentine, copaiba) and gum resins containing essential oils (ammoniacum,
asafoetida,
gamboge,
myrrh, and scammony) are more largely used for therapeutic purposes and
incense.
Resin in the form of
rosin is used for the upkeep of bows for stringed instruments (i.e. violin,
viola,
cello,
double bass), because of its quality for adding friction to the hair.
Resin has also been used as a medium for sculpture by artists such as
Eva Hesse, and in other types of artwork.
Also, resin is used in some
skateboard decks. It makes the skateboard more durable, making it less likely to get pressure cracks, chippings, or break in half.
Akira Ifukube, who wrote and composed the music to numerous
Godzilla (film series), also created Godzilla's roar by rubbing a resin-covered leather glove over the loosened strings of a
double bass.
