TECHNICAL DETA SHEET FOR SHREECRYL SS-565

Low tack, medium adhesion value solution polymer for coating
Films for surface protection - steel, acrylic sheets, glass etc.

PHYSICAL APPEARANCE	SS-565 is a very clear solvent based acrylic resin of medium viscosity, free flowing product without any type of visible particles.
CHEMICAL NATURE	It is a polymer of more than four very active acrylic monomers in solvent phase by strict control of the rate of reaction between the very active monomers by means of controls in the hands of highly experienced technologists.
NON - VOLATILES	47 - 48%
pH VALUE of Water (Method : Take 1:1 by weight, the product And distilled water in a conical flask, stir well & then in a hot water bath, heat the mixture to 80- 85º for 5 – 10 minutes & cool it down. At room temperature, decant the clear water into a beaker and check the pH value.)	3 - 5
Free monomer	Below 0.5% (After neutralising acidity of solvent & other constituents)
Film on glass	Very clear without any particles/coagulum
Tack on film (Rolling Ball Method at 45⁰angle)	Excellent
Drying Rate	Fast Drying
Surface Tack	NIL
Flow of product when freely poured	Very free flow (no gels or lumps) when poured.
Viscosity by Brookfield RVT Model Sp.No.4/5, at 20 rpm at 30^oC	15 – 40 poises.
Resistance to water : a. 30 gsm film on 30 micron polyster cured at 88^oC for 8 -9 minutes.Next day dip it in water for 48 hours. b. Film coated on glass, 30 gsm, cured at 88^oC for 8 -9 minutes. Next day poured water on part of the film for 48 hours.	a. No colour change / whitening b. No colour change / whitening & no loss of tack & strength.

COMPATIBILITY :
Shreecral SS-565 is compatible with solvents like ethyl acetate, isopropyl acetate, butyl acetate, toluene, Xylene.
SS-565 is compatible with Polyterpene or Hydrocarbon tackifiers (Softening point 110 - 115^oC) at 1 - 2% by weight dissolved in toluene (50:50 by weight)
The dried film is resistant to transformer oil, water.

USE OF SHREECRYL SS-565

SS-565 is a ter-copolymer with low tack & medium adhesion value. It is used to coat protective films for Steel, Acrylic sheets, glass. The films are PET, HDPE, LLDP, Paper etc. Roller coating.

APPLICATION TECHNIQUES:

1. Roller coating on substrate directly to be nipped with other substrate in wet condition & then to be nipped under pressure roller.

2. By Brush / Spray Dilute the product from 50% to 33% by adding solvent (Ethyl Acetate / Toluene) & mixing well to homogenize. Then either brush uniformly on required side of one or both substrates to be joined & bond as soon as possible (in wet condition) Keep the joint under pressure for 12 – 24 hours. The product is fast drying. To delay drying, Toluene can be used

DO'S & DO NOT'S

1. Check the supply for any micro-gels, which can cause non-uniform application tack.

2. Do not keep the product under abnormal conditions of storage, like temperatures above 30ºC to avoid solvent loss and viscosity pickup due to solvent loss or cross linking.

3. Do not keep the drum/carboys filled with SS-565 open near heat or flame. SS-565 is highly flammable due to Ethyl Acetate.

4. As it is a solvent based system, shelf life is not warranted above 6 months. Hence, no complaints what so ever will not be entertained after six months from the date of manufacture.

ADVANTAGES OF SHREECRYL SS-565

1. Being manufactured under the personal supervision of highly qualified & experienced persons, the product has excellent consistency regarding viscosity, strength, clarity, and molecular weight distribution and flow properties.

2. Due to uniform copolymerisation, the shelf life is longer compared to a product-polymerized haphazardly just to get viscosity.

3. The product has better shelf life.
4. The maximum shelf life is within 6 months from the date of manufacture (Month & Year of manufacture is included in the batch no. displayed on the barrels / containers).
