TECHNICAL DETAILS OF SHREECRAL PS-25

SHREECRAL PS-25 (ACRYLIC COPOLYMER FOR STICKERS /
BINDIS / LABELS / INSULATION TAPES

PHYSICAL APPEARANCE Bluish white copolymer free flowing emulsion
CHEMICAL NATURE
PS-25 is an Acrylic copolymer dispersing agents, tackfiers, buffers to retain long shelf life, permanent, non transferable take etc.
NON - VOLATILES 49.5 %
pH VALUE of Water 4 - 6
ACID VALUE 1 - 3 mgm of KOH/gram of substance
COLLOID / STABILISER
Cellulose derivative and special quality polyvinyl alcohol and various surfactants
PARTICLE SIZE 0.5 - 1 microns, very fine size
Viscosity by Brookfield viscometer RVT Model spindle 4/5 at 20 rpm and 30o C
60 - 80 Poises
DRYING RATE
Moderate to allow medium speed production of stickers by screen printing. PS-25 works for roller application on silicon paper and then film is released on to the paper roll.


COMPATIBILITY :
Shreecral PS-25 is compatible with palsticisers like DBP, DEP solution of Polyvinyl alcohol, surface active agents, fungicides etc. It is compatible with water

APPLICATION TECHNIQUES :
Shreecral PS-25 is applied by screen, usually 15-25 No. (150-250-mesh size) for making conventional stickers, bindis & labels. Now a days to increase production, roller application of glue on release paper and then transfer to paper in roll form is gaining importance for which glues generally available do not work well. Shreecral PS-25 has been developed to suit this application in particular

USES
1. It is a leading product for stickers of all types, paper/ PVC Cellophane.
2. It is economical and excellent for BINDI making, as PS-25 has no side effect on skin on prolonged exposure to gummed bindis. It is non-toxic to skin.
3. For making stock paper or stickers in roll form on continuous roller coating. The glue has excellent dispersing agents which enhance the coverage as well as uniform coating on the paper. 4. PS-25 gives a clear film on PVC (transparent film).

ADVANTAGES
1) More coverage, better tack, non transferability of glue once the sticker dries.
2) Developed by professional Technocrat whose AIM is to go on improving the quality to give satisfaction to the customers.
3) Unlike other grades which do not work well for roller application, PS-25 works extremely well.
4) Especially for sanitary napkins & high temperature resistant, permanent stickers, PS-25 is very safe as the monomer content left over after the polymerisation is well below 0.5% &there are no ingredients in the system which are detrimental to human body/skin.

DO'S & DO NOT'S
1) Do not mix with any other brand of PS/PSA/PSV.
2) Do not unnecessarily thin down with water.
3) Use clean screen and squezee. After work, clean the sieves thoroughly with kerosene/spirit to avoid choking of the screen.
4) Keep the Container containing PS-25 closed to avoid contamination and skinning.
5) Store the glue under normal temperatures.
6) Due to its unique / bluish tinge and butter like felling as well as the properties is easy for the user to identify Shreecral PS-25 from fake products. The carboys are printed and batch number marked on each .

PACKING SIZE 200 kgs, 50/30 kgs, 5kgs
