Authorized Distributor
Chemical
Specialty colourants and intermediates supplied as an authorized distributor: Phthalogen ingrain blues, organic yellow pigments, and the phthalocyanine and sulphonamide intermediates behind them. Good quality, competitive prices and fast delivery, through a direct manufacturer channel.
Overview
Specialty chemistry, supplied to specification.
Authorized status means three things for the buyer. Manufacturer pricing without a broker margin. Documentation traceable to the producing batch rather than to a repacker. And allocation taken straight from the production schedule instead of whatever the open market happens to be holding that week.
The practical result is the combination that is usually hard to find in specialty chemistry: consistent quality, competitive pricing and fast supply, with typical despatch on listed grades within four to seven days. Every consignment is checked against specification before it leaves, and customised grades and packaging are available on request.
- Authorized distribution with manufacturer traceable documentation
- Competitive pricing and typical despatch in four to seven days
- Customised grades and packaging available on request
One intermediate. Three product families.
1,3 Diiminoisoindoline is the starting point for the Phthalogen ingrain blues and for the isoindoline yellows PY139 and PY185 in this range. Buying across that family from one authorized source keeps the chemistry, the documentation and the quality control on a single chain rather than spread across unrelated suppliers, which is where batch to batch variation usually creeps in.

Our range
What we supply.
Every product is supplied against the grade, the purity and the volume your process requires.
Phthalogen Ingrain Blues
Ingrain dyes are applied as a precursor and develop their final phthalocyanine colour on the substrate itself, which is what gives this class its brilliant blue shade and very high fastness.
Phthalogen Brilliant Blue IF3G
Ingrain blue dye
The IF3G grade of the Phthalogen ingrain range. It develops a brilliant turquoise blue on the substrate, with the wash and light fastness that phthalocyanine chemistry is known for, and is supplied in customised form on request.
