Compatible with cure chemistry
Pigment must not interfere with the reactive cure of silicone, polyurethane or epoxy systems, so confirm compatibility before it affects bond performance.

Pigments for Adhesives & Sealants
Organic pigments for adhesives & sealants sourced from India with grade selection, documents, and export support.
Adhesives and sealants are tinted mainly for identification, coverage or aesthetics, and the pigment must sit stably in reactive or solvent systems without disturbing cure, adhesion or shelf life. Organic pigments provide strong, clean colour at low loading, but must resist migration and bleeding, especially in flexible sealants where plasticiser mobility is high. Buyers sourcing from India should confirm chemical compatibility with the polymer chemistry, non-bleeding and non-migrating behaviour, stability without seeding or settling during storage, and, for exterior sealants, adequate light fastness on visible joints.
At a glance
What Pigments for Adhesives & Sealants covers
Non-bleeding in sealants
Flexible sealants carry mobile plasticisers, so migration-resistant pigments stop colour bleeding into substrates or adjacent light-coloured joints.
Storage stability
Pigment should stay evenly dispersed without seeding or hard settling over shelf life, so the product colours consistently from first use to last.
Exterior light fastness
Visible facade and construction joints need lightfast grades so exposed sealant beads keep their colour instead of fading against the substrate.

Answers
Pigments for Adhesives & Sealants — frequently asked questions
Will pigment affect adhesive cure or bond strength?
The right, inert, well-dispersed pigment at normal loading does not impair cure or adhesion, but some pigments carry moisture or surface treatments that can interfere with reactive systems. Always confirm compatibility with your specific silicone, PU or epoxy chemistry before scaling up.
How do you stop colour bleeding in flexible sealants?
Flexible sealants contain mobile plasticisers that can carry weak pigment into substrates or adjacent joints. Selecting high-performance, migration-resistant organic grades keeps colour locked in the bead, which matters most where sealant meets pale stone, render or trim.
Which pigment form suits adhesive manufacturing?
Options include pigment powder, dispersions or pigment concentrates matched to the resin base. Liquid concentrates ease clean dosing and dispersion in continuous production, while powder suits some reactive systems. The best form depends on your polymer chemistry and mixing process.
Do pigments reduce sealant shelf life?
Properly selected inert pigments should not shorten shelf life, but poorly stabilised ones can seed, settle or absorb into reactive components over time. Confirming storage stability and compatibility up front protects both colour and the sealant's working life.
