Covai Seenu & Company has established itself as a renowned supplier and distributor of pigments. The company is anauthorized distributor for
KEROXChemicals and
SUVARNA Chemicals who have expertise in manufacturing pigments.
We offer
KEROX pigments which are known for their excellent quality, good compatibility, and color uniformity. Our experts select these pigments because of their following properties:
- Light Fastness
- Outdoor Durability
- UV Resistance
- Heat Resistance
- Chemical Resistance
- Electrical Properties
- Toxicity
Usage Level:(Based On Weight)- 8- 12% for gelcoat
- 4-6% for laminates
- 8-10 % for sheet/dough moulding compounds
- 1-5 % for translucent sheets
- 4 -6 % for filled castings
- 8-10 % for pultrusions.
nder-pigmentation may lead to non-uniformity of colour and other surface defects. Higher pigmentation will provide better uniformity, colour depth, brightness, and longer durability.
Mixing Instructions:KEROX Pigments tend to readily mix along with polyester resins. In fact small quantities can even be mixed with hand stirring. The slow paddle type mixers available nowadays are the preferred choice since they minimize aeration which takes place during mixing. A weighed quantity of the pigment is first charged into a mixing vessel. A small quantity of resin is then added and mixed until uniform colour is obtained, and then when the remainder of the resin is added and mixed.
Note:- On no account should a small quantity of the pigment be added to a large bulk of the resin before first thinning.
The accelerator may be added to large pigmented master batches and stored for 24 hours or longer without loss of activity before use. Small lots of pigmented/pre accelerated resin may then be catalysed before use.
Storage Stability:KEROX Pigments have excellent stability in storage and minimum guaranteed shelf-life is 6 months. Storage below 25 degree C is recommended for longer shelf life.
Colour Matching:KEROX Pigments can be mixed with one another to obtain intermediate shades. Dark shades present no particular problem, but pastel shades may be difficult. Colours can be matched to customer’s requirements provided the minimum quantity is large.
EPOXY Pigments:Pigments dispersed in polymeric plasticisers are available for colouring epoxy laminates and castings. At 5-10% levels of usage, the plasticisers will have no adverse effect on the cured resin. Pigments dispersed in liquid epoxy resin can be supplied for special applications.
SUVARNA Pigments:These are made by dispersing dry pigments powders in non styrenated & polyester resin and used for coloring of fiberglass reinforced plastics (FRP).
The primary pigments are selected for their following properties
- Light Fastness
- Outdoor Durability
- UV Resistance
- Heat Resistance
- Chemical Resistance
- Electrical properties
- Toxicity
User Level:The following levels based on the weight of resin are recommended:
Mixing Instruction:SUVARANA Pigments readily mix with polyster resins. Though small quantities can be easily mixed by hand stirring for large quantities power mixing is necessary.
Storage Stability:SUVARANA Pigments have excellent stability of about 6month if stored at 25 degree C
Colour Matching: Special shades can be matched if the requirements are large.
