Application

HIMIDE 1002/H has excellent nitrocellulose compatibility and optimum performance of and ink is obtained with relatively high levels of nitrocellulose. The low odour of HIMIDE 1002/H makes it suitable for food packaging inks. HIMIDE 1002/H complements HIMIDE 9030 and between them they span the normally encountered levels of nitrocellulose with HIMIDE 9030 being suitable for lower levels. A solubility characteristic of HIMIDE 1002/H is excellent and is gelation resistance. HIMIDE 1002/H can be considered as a general purpose, alcohol soluble resin for flexographic inks.

Packaging

Available in 25 kg bags normally 500 kg per pallet.

Shelf Life

Store under cool, dry conditions, It is recommended that the material be used within 12 months of certification.

Handling

HIMIDE polyamide resins are not classified as dangerous and present little or no toxic hazard at normal ambient temperatures, providing good standards of industrial and personal hygiene are practiced.
However, dust may be produced during handling and the wearing of protective masks and precautions to avoid potential dust explosion etc. are required.

The properties measured for every development or production resin include those related to the chemistry of resin, and those specific to its performance as on ink.

Knowledge of resin chemistry is essential to obtain reproducibility of molecular weight and other physical parameters. Similarly, a knowledge of those properties related to solution and film behavior is required to ensure that satisfactory ink performance is obtained.

Study of all these properties allows the effect of compositional and process changes on ink performance to be assessed.

All comparisons are made using the resin in unmodified form. For continuity, the modifying resin used is a spirit soluble, 1/8 sec. nitrocellulose, which is compatible with all resins at the level used. It is appreciated that many other type of modifying resin are used depending upon the final properties required.

Softening Point

The softening (or melting) point is measured using the ring and ball method with a heating rate of 5 0C per minute. The result is expressed in °C

Acid Value

The acid value is determined by titration with 0.1N alcoholic potassium hydroxide solution using phenolphthalein indicator. The results expressed in mg KOH/g of resin.

Amine Value

The amine value is determined by titration with 0.1N hydrochloric acid using bromo cresol green indicator. The result is expressed in mg KOH/g of resin.

Colour

The colour is determined on a 35% nvc solution in n-propanol using a comparator. The results are expressed in terms of unit on the Gardner scale.

Varnish Properties

The varnish properties are determined on a 35% nvc solution of the test resin in n-propanol. The resin is tested unmodified and modified with 20% of an “alcohol soluble” nitrocellulose resin based on resin solids.

Gel Recovery

The gel recovery temperature is the temperature at which the test resin solution becomes liquid after storage at-12 °C for 16 hours.

Polar Solvent Tolerance

The solvents use for determining the polar tolerance is either industrials methylated spirit or ethyl acetate. The amount of polar solvent required to precipitate the test resin from solution is determined and the tolerance is expressed as a percentage over the original resin solution (i.e.1 part resin solution to 1 part polar solvent is 100% tolerance;1 part resin solution to 1.5 parts polar is 150% tolerance).

Solvent Release

Solvent Release is measured as the relative drying rate of the test solution against a fast drying, high molecular weight co-solvent solution (HIMIDE 831, at 35% nvc in n-propanol). A twin channel grind gauge is used. The result is expressed on an arbitrary scale of 0-10, with the standard expressed as 5.

Anti Blocking

Anti blocking is measured as the degree of adhesion between varnish film(varnish to varnish) stored for 16 hours at 40°C and 90% relative humidity under a 1 kg weight.

Ink Properties

The ink properties are determined on flexo graphic inks made from the resin alone and resin modified with nitrocellulose. The inks are pigmented with phthalocyanine blue at a pigment/binder ratio of 0.36:1

Wet Scratch Resistance

The wet scratch resistance is expressed as the resistance of the film to marring or removal by fingernail after being soaked in water at 25°C for 3 hours.

Wet Crinkle Resistance

The wet crinkle resistance is the number of crinkle to remove or damage the film after soaking in water at 25°C for 3 hours.

A. PRECAUTIONS

1. General

Solid polyamide resins not normally harmful, but can present a dust hazard.

2. Skin Protection

Not normally harmful.

3. Eye Protection

Avoid contact with eyes. Wear eye protection at all times when handling polyamide resins.

4. Respiratory Protection

Avoid breathing dust. Wear suitable dust make when handling polyamide resins.

5. Protection From Fire and Explosion Hazards

The main hazard is represented by dusting from solid polyamide resins. Avoid sources of ignition and take precautions to avoid build up of static.
Efficient ventilation to minimize dust concentrations is essential.
In the event of fire, suitable extinguishers are foam and dry powder carbon dioxide.
Combustion of the resins may yield toxic by-productions; therefore, fire fighters should wear suitable protective clothing including breathing apparatus.

6. Environmental Considerations

Not normally dangerous for the environment.

B. FIRST AID

C. STORAGE

Store away from sources of ignition.

D. SPILLADE

Powder spillages should be swept up; avoid causing excessive dust, and placed in closed containers for disposal.

E. DISPOSAL

All wastage must be disposed of in accordance with the requirements of the Pollution Control Act.
N.B. when the above resins are formulated into end productions, due account must be taken of other
constituents of the formulations on their handling hazards.
