ADCRYL
P.S. ADHESIVE
Acrylic Solvent Based
Description :
Adcryl
P.S. Adhesives are self - crosslinking acrylic co polymers
prepared in a mixture of low boiling solvents. On drying, they
give clear transparent and permanently tacky film. These P.S.
Adhesives show optimum balance of adhesive and cohesive
properties.
Applications :
Adcryl
P.S. Adhesives can be used as such but can also be diluted to
adjust viscosity and solid content for a particular application.
Adcryl P.S. Adhesives can be applied by roller coating, direct and
reverse. Substrates coated with Adcryl are capable of giving
bonding with a wide variety under gentle pressure. Film of Adcryl
can be converted into a highly crosslinked thermosetting type by
curing at 150°C to 160°C for 10 to 20 minutes. This treatment also
improves the electrical properties of the film.
Advantages
:
1.
Thermoplastic and single component self crosslinking system.
2. Excellent ageing properties.
3. Non Toxic and odourless after the film is dry.
4. Unaffected by sunlight and has good electrical and thermal
properties.
Uses :
1.
Manufacturing self adhesive tapes with paper, PVC, polyester, BOPP,
etc as the substrates.
2. To make pressure sensitive paper, PVC sheets, aluminum foils.
Radio, T.V. cabinets,
decorative furniture’s, pressure tags, etc.
3. It can also be used for lamination with various substrates by
mixing with primary/ secondary/ cyclic amines.
4. As pressure sensitive adhesive for splicing in paper mills,
etc.
Diluents :
Adcryl
P.S. Adhesives can be diluted with ethyl acetate, toluene, hexane,
xylene, etc. By using proper combination of diluents, drying times
can be controlled or adjusted. However for most applications,
dilution is not necessary and the adhesive can be used directly.
Compatibility:
Adcryl
P.S. Adhesive are compatible with plasticizers such as DOP, DBP,
Paraplex G 54. This increases adhesive strength and ability of
quick bonding, but also reduces cohesive strength. Adcryl P.S.
Adhesives are also compatible with polyterpene and hydrocarbon
tackifiers. The other additives that can be added is tricreysl
phosphate which gives fire retardancy properties.
Coverage
:
Adcryl
P.S.Adhesives give coverage of 7.5 sq.mtrs/ kg as against 4
sq.mtrs/ kg by the conventional rubber based adhesive. Coating
weight required for the optimum performance depends upon the
nature of the substrates. Optimum coating weight required for a
few common substrates are given below:
------------------------------------------------------------------------------------------------------------
No.
Substrate
Coating weight required
------------------------------------------------------------------------------------------------------------
1. Paper- maplitho, chromo,
etc 20 to 25 gsm
2. Brown packing
paper
25 to 30 gsm
3. Polyester, metallised polyester,
cellophane 18 to 20 gsm
4. BOPP- carona
pretreated 15 to 20
gsm
5. Plasticized PVC film, PVC Sheet,
etc 15 to 20 gsm
6. Aluminium
foil
15 to 20 gsm
7. Polyethylene Corona treated
10 to 15 gsm
8. Fibre glass
film
25 to 30 gsm
-----------------------------------------------------------------------------------------------------------
Note :
Coating weight in far more excess or less than the prescribed
limit may affect the performance of the adhesive.
Precautions
and Storage :
Adcryl
P.S. Adhesives are inflammable and volatile. They should be stored
in a well ventilated cool dark place away from direct sunlight and
flames. The containers/ drums should be kept tightly closed after
each use. Depending on the conditions of storage, Adcryl P.S.
Adhesives have a storage life of 6 months from the date of
manufacture.
Health
and Safety Aspect:
Keep
away from heat , sparks and open flames. Adhesive contains highly
inflammable solvents. Use with adequate ventilation. Harmful or
fatal if swallowed. If swallowed, call physician immediately. For
more details, please refer to our Material Safety Data Sheet.
