Frequently Asked Questions

General

Q. What is an adhesive?

A. A substance that unites or bonds two surfaces together.

Q. What is adhesion?

A. Adhesion is the attraction that allows molecules of different kinds to stick together.

Q. How do I know which adhesive to use?

A. You need to take into account the following factors:

What is the application?

What is the material?

What is the environment?

Please contact us or your nearest stockist for assistance.

Q. How should I store my adhesives?

A. Adhesives with the exception of acrylic adhesives should be stored in a comfortable room temperature 18° and out of direct sunlight to maximise their shelf life.  Acrylic adhesives such as Superglue, Eezebond® and 1-2-3 Quickset®, should be stored in cooler temperatures generally between 4-7°.

Q. Do I need to clean my surfaces prior to applying an adhesive?

A. It is always recommended that your working surface is clean of any film or residue prior to applying an adhesive.

However some products such as Eezebond® and 1-2-3 Quickset® can be applied to oily surfaces without affecting their performance.

Pratley's non flammable safety cleaner is recommended for preparing your working surface.

Q. Where can I obtain a material safety data sheet?

A. Material Safety Data Sheets can be obtained on request through this website or on request through your stockist.

Q. What number do I contact for first aid measures?

A. The number for Australia is 131126

Q. I purchased a bottle of superglue and it is only half full.  Why?

A. Bottles are only half full to allow air to also be trapped inside to prevent the liquid from solidifying.

 

Epoxies

Q. How strong are epoxies?

A. Epoxies are generally two-part and are the highest strength group of adhesives.

Q. What two parts make up an epoxy?

A. An epoxy is made up of a resin and hardener.

Q. What temperature can an epoxy putty or glue withstand?

A. No epoxy can withstand temperatures greater than 180°.  A comfortable, working temperature is 80°.

Q. Do I need to apply heat for an epoxy to cure?

A. No.  The resin and hardener create a reactive cure at room temperature.

 

RABDA

Q. What does RABDA mean?

A. RABDA is the abbreviation for: Reactively Accelerated Blocked Diocyanate Alloy.

Q. What is an RABDA?

A. It is an adhesive which combines the strength of an epoxy and the reliability of a urethane in one.

 

Acrylics

Q. What are acrylic adhesives?

A. They are fast curing and strong adhesives.

Q. Do Pratley's acrylic adhesives have gap filling properties?

A. Acrylic adhesives generally don't have gap filling properties.  Eezebond® and SP020® do allow a degree of gap filling.

 

Anaerobics

Q. To what standard does Pratlok® conform to?

A. Pratlok® conforms to ASTM D 5363-03, ISO 10964 & ISO 10123.

Q. Are the liquids U.V. Fluorescent?

A. Yes

Q. I purchased a bottle and it is only half full. Why?

A. Bottles are only half full to allow air to also be trapped inside to prevent the liquid from solidifying.

Q. Do I need to clean my parts prior to applying an anaerobic?

A. It is always recommended that you clear the surface prior to application of an anaerobic so that the surface is clear of any film or residue.  Pratley's non flammable safety cleaner is recommended.

Q. The liquid material is coloured.  What is the significance?

A. The various colours generally signify the overall strength of the anaerobic.  Other colours are specific to strengths in relative areas.  Generally speaking, the following applies:

Purple - low strength

Blue - medium strength

Red - high strength

Q. Do I need to use an activator?

A. An activator is required to cure Pratlok® on inactive materials, to speed up the cure process in low temperatures or in difficult conditions.

Q. What materials are considered active and inactive?

A. Please consult the following list:

Active

Steel - raw
Copper
Nickel
Iron
Brass
Bronze
Kovar
Manganese
Commercial Aluminium
Monel
Cadmium
Galvanized Steel
Magnetite steel

Inactive

Surface coated parts
Stainless Steel
Zinc
Silver
Gold
Magnesium
Titanium
Anodised Aluminium
Pure Aluminium
Black Oxide

 

Q. What does viscosity refer to?

A. Viscosity refers to a fluids resistance to flow.  If a liquid is referred to be low in viscosity that indicates that it is thin.  Similarly if a liquid is referred to be high in viscosity that indicates that it is thick.

Q. Can heat be applied to accelerate the cure process?

A. Yes.

Q. Does Pratlok® provide corrosion resistance?

A. Yes.

Q. Is Pratlok® highly toxic?

A. Pratlok® yields low levels of toxicity.

 

Sealants

Q. How flexible is flexiseal?

A. Flexiseal yields 300% elongation in application.

Q. Does the silicone have any water in its composition?

A. Pratley silicone is 100% acetoxy.
